Write the equation of the line parallel to y=4x+89 through the point (1,5)
Write the equation parallel to y=-7x+12 through the point (-2,0)
Write the equation of a line parallel to x=24
Write the equation of a line Perpendicular to y=12
The equation of the line parallel to y = 4x + 89 and passing through the point (1, 5) is y = 4x + 1.
The equation of the line parallel to y = -7x + 12 and passing through the point (-2, 0) is y = -7x + 14.
The given equation, x = 24, represents a vertical line passing through x = 24.
The equation would be y = (-1/12)x + b, where b is the y-intercept value.
How to explain the equationy - 5 = 4(x - 1)
Simplifying, we get:
y - 5 = 4x - 4
Now, rearrange the equation to the slope-intercept form:
y = 4x + 1
y - 0 = -7(x - (-2))Simplifying:
y = -7x + 14
Parallel to x = 24:The given equation, x = 24, represents a vertical line passing through x = 24. Parallel lines to vertical lines are also vertical lines with the same x-coordinate.
Therefore, any line parallel to x = 24 will have the equation x = k, where k is a constant. The value of k can be any real number, as long as it remains constant.
Perpendicular to y = 12:
The given line has a slope of 12, so the perpendicular line will have a slope of -1/12.
Therefore, the equation of the line perpendicular to y = 12 will be in the slope-intercept form y = mx + b, with m = -1/12

Find the length of each side of the triangle.
Answer:2x - 5cm + 3x +2cm + 2x - 1cm=59cm
2x + 3x + 2x + 2cm + 1cm - 5cm=59cm
7x - 2cm=59cm
7x - 2cm + 2cm=59cm + 2cm
7x=61cm
X=8 5/7cm
Step-by-step explanation:
The length of the sides of the triangle will be equal to 13 cm, 29 cm, and 17 cm.
What is the perimeter?A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any geometric two-dimensional shape. The circumference of several figures could be compared based on the measurements.
As per the given information in the question,
The perimeter of the triangle = 59 cm
Use the formula of the perimeter of a triangle,
P = a + b + c
59 = 2x - 5 + 3x + 2 + 2x - 1
59 = 7x - 4
7x = 59 + 4
7x = 63
x = 9
Then, the lengths of the side will be,
2x - 5 = 2(9) - 5 = 13 cm

When adding polynomials are the exponents always added together?
Answer:
No
Step-by-step explanation:
Exponents are only added when polynomials are multiplied and only applies to like terms. You add the coefficients of the like terms instead.
For example:
\((x^2+3x+6)+(2x^2-4x+1)=(1+2)x^2-(3-4)x+(6+1)=3x^2-x+7\)
Answer:
no
Step-by-step explanation:
The exponents are added when the the same coefficient is multiplied:
\(x^2(x^3) = x^5\)
If you think about it:
x^2 = x * x and x^3 = x * x * x
so you get:
(x^2)(x^3) = x * x * x * x * x = x^5
But, when adding x's of the same power, you add a coefficient:
\(x^2 + x^2 = 2x^2\), not \(x^2 + x^2 = x^4\)
Always remember to only add exponents when the coefficient/variable is multiplied, not added.
And, when an exponent is put to an exponent, multiply them:
\((x^3)^3 = x^3^(^3^) = x^9\)

The manager of a fast food restaurant is supposed to serve coffee that is 160 degrees Fahrenheit. A random sample of 20 cups of coffee reveal that the mean temperature is 151 degrees Fahrenheit with a standard deviation of 3 degrees. The manager would like to conduct a t-test for the population mean temperature of all cups of coffee served at this restaurant. Are the conditions for inference met?
No, the random condition is not met.
No, the 10% condition is not met.
No, the Normal/large sample condition is not met.
Yes, all conditions for inference are met.
Answer:
C. No, the Normal/large sample condition is not met.
Step-by-step explanation:
There is only 20 cup and for a sample to meet the Normal/large sample condition it must be greater than 30 samples or have a normal distribution or have no skewness or outliers
No, the Normal/large sample condition is not met.
Option C is the correct answer.
What is a t-test?A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups or samples.
It is used when the sample size is small or the population standard deviation is unknown.
We have,
The conditions for inference in a t-test are:
Random condition:
The sample should be selected randomly from the population to ensure that the sample is representative of the population.
Normal/large sample condition:
The population should be normally distributed, or the sample size should be large enough to assume normality. A commonly used rule of thumb is that the sample size should be at least 30.
Independence condition:
The observations in the sample should be independent of each other.
In this case,
The random condition is met as the sample was selected randomly. However, the normal/large sample condition is not met since the sample size is only 20, and it's not clear if the population of coffee temperatures is normally distributed.
Therefore, the conditions for inference are not met, and a t-test for the population mean temperature of all cups of coffee served at this restaurant cannot be conducted.
Thus,
No, the Normal/large sample condition is not met.

Suppose a consumer's utility function is given by U(X, Y) = X*Y. Also, the consumer has $360 to spend, and the price of X, Px=9��=9, and the price of Y, Py=1��=1.a) How much X and Y should the consumer purchase in order to maximize her utility?b) How much total utility does the consumer receive?c) Now suppose Px=9��=9 decreases to 4. What is the new bundle of X and Y that the consumer will demand?d) Of the total change in the quantity demanded of X, how much is due to the substitution effect and how much is due to the income effect?e) How much money would the consumer need in order to have the same utility level after the price changes as before the price change?
a) To maximize utility, the consumer should purchase X and Y such that the marginal utility per dollar spent on X and Y is equal. That is, MUx/Px = MUy/Py. Plugging in the utility function and prices, we get (Y/9) = (X/1). Solving for X and Y and using the budget constraint of $360, we get X = 40 and Y = 360. So the consumer should purchase 40 units of X and 360 units of Y to maximize utility.
b) The total utility the consumer receives is U(40, 360) = 40*360 = 14400.
c) With the decrease in the price of X to 4, the new budget constraint is 4X + Y = 360. Plugging in the utility function and solving for X and Y, we get X = 60 and Y = 240. So the new bundle of X and Y that the consumer will demand is 60 units of X and 240 units of Y.
d) The substitution effect is the change in quantity demanded due to the change in relative prices, holding utility constant. The income effect is the change in quantity demanded due to the change in income, holding prices constant. To find the substitution effect, we need to find the bundle of X and Y that gives the same utility as before the price change but with the new prices. Solving for X and Y, we get X = 45 and Y = 320. So the substitution effect is 45 - 40 = 5 units of X. The income effect is the difference between the new quantity demanded and the quantity demanded with the substitution effect, or 60 - 45 = 15 units of X.
e) To have the same utility level after the price changes as before the price change, the consumer would need enough money to purchase the original bundle of X and Y at the new prices. That is, 4(40) + 1(360) = $520. So the consumer would need $520 in order to have the same utility level after the price changes as before the price change.

Mike drank 60% of his glass of milk. Afterwards, 80ml of milk remained in the glass. What volume of milk was initially in the glass?
Answer:
Step-by-step explanation:
\(x\) is the total volume of milk.
100% - 60% = 40%
40% is left in the glass.
40% of \(x\) = 80 ml
\(\frac{40}{100}\) of \(x\) = 80
\(x = 80\) × \(\frac{100}{40}\)
\(x = 200\) ml
The volume of milk initially in the glass was 200 ml.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Let x be the total volume of milk.
100% - 60% = 40%
40% is left in the glass.
40% of x = 80 ml
40 / 100 × x = 80
0.4 × x = 80
x = 200
Thus, The volume of milk initially in the glass was 200 ml.

The y-intercept of the least squares regression line is 5.5.
Describe Linear Regression?Linear regression is a statistical method used to analyze the relationship between two variables by finding a linear equation that best fits the data. The goal of linear regression is to predict the value of one variable based on the value of another variable.
The equation for a simple linear regression model is:
y = mx + b
where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept (the value of y when x is zero).
The equation of the least squares regression line is given by:
y = a + bx
where "a" is the y-intercept and "b" is the slope. We are given the slope as 0.62 and also know the means of x and y. So, we can substitute these values into the equation to solve for the y-intercept:
21 = a + 0.62(25)
21 = a + 15.5
a = 21 - 15.5
a = 5.5
Therefore, the y-intercept of the least squares regression line is 5.5.

Statement D, "The values x = -6 and x = 6 are both zeros of f(x)," must be true based on the given information.
Since f(x) is evenly divisible by (x + 6), it means that (x + 6) is a factor of f(x). This indicates that when x = -6, f(x) will be equal to zero. Therefore, x = -6 is a zero of f(x). However, the given information does not provide any direct evidence to support the statements A, B, or C. It does not guarantee that (x - 6) is a factor of f(x) (statement A). Additionally, it does not provide information about the remainder when dividing f(x) by (x - 6) (statement B) or the remainder when dividing f(x) by (x + 6) (statement C). These statements cannot be determined solely based on the given information.
