Answer 1

Answer:

Number 7-    +3

Number 8: slope: -4

                   y- intercept: +140

Step-by-step explanation:

for the first question, i picked the points (0, 2) and (-1, -1). i used the slope form y2-y1/x2-x1 or in this case -1-2/-1-0 which equals to -3/-1=3. for the second question you subtract 120-140/5-0 which equals -20/5 simplified to -4 and the y intercept is 140 because x=0

Hope this helped! :))

Find the missing number so that the equation has infinitely many solutions. – 5x–19= (Blank)x–19

Answers

Answer:(number)=-5

Step-by-step explanation:

You can use simple logic in order to solve this equation.

An equation that has infinitely many solutions will have the same exact numbers on both sides

Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true

The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Jerome is cooking dinner. He needs 8 ounces of broccoli for each person.

Part A: Jerome is not sure how many people will come to dinner. Write an expression with a variable that represents the amount of broccoli Jerome needs for dinner. Identify what the variable represents.

Part B: If Jerome has 32 ounces of broccoli, how many people can he feed? Create an equation and show all work to solve it.

Answers

Answer:

Part A: 8Bp (8 b(broccoli) times p(people)

If Jerome has 32 ounces of broccoli then he can feed 4 people

32 pieces of broccoli divided by the 8 piece of brocoli per person will tell you that he will have 4 pieces of broccoli

Answer:

Part A

lets just say 5 people come for dinner so 5x8 = 40 so he will need 40 ounces of broccoli

Part B    so  8 ounces per person and he has 32 ounces so he will have feed 4 people

Tyrell is traveling to Chicago, Illinois. He takes a cab service from the airport to his hotel. The table shows the linear relationship between the number of miles the cab travels, x, and the total fee, y.


Cab Fare
Number of Miles Total Fee
2 $13.00
5 $17.50
7 $21.50
10 $25.00
15 $32.50


What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.

Answers

The meaning of the y-intercept in this situation is that: D. when the cab travels 0 miles, the total fee will be $10.00.

How to calculate the slope of a line?

Mathematically, the slope of a straight line can be calculated by using this formula;

From the table, we have the following parameters:

Points (x, y) = (2, 5) and (13.00, 17.50)

Next, we would calculate the slope as follows:

Slope = (17.50 - 5)/(13.00 - 2)

Slope = 12.50/11.

Slope = 1.14.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

Where:

x and y represents the points.

m represents the slope.

b represents the y-intercept.

Substituting the given parameters into the standard equation, we have;

y - 13.00 = 1.14(x - 2)

y - 13.00 = 1.14x - 2.28

y = 1.14x - 2.28 + 13.00

y = 1.14x + 10.72

Answer: D When the cab travels 0 miles, the total fee will be $10.00.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

1. 30 inches to 24 inches

2. $126 to $150

Answers

1. 20% decrease

2. 16% increase

Explaination:

Question 1.

30 inches to 24 inches is a decrease, because 24 is smaller than 30.

(30-24)/30 * 100%

= 6/30 * 100%

= 20%

Ans: 20% decrease


Question 2.

$126 to $150 is an increase, because 150 is larger than 126.

(150-126)/150 * 100%

= 24/150 * 100%

= 4/25 * 100%

= 16%

Ans: 16% increase

Answer:

16%⬆

Answer:

C = 2π(3/8) = 3π/4 units

Step-by-step explanation: The area of the circle is given by the formula A = πr^2, where A is the area and r is the radius.Therefore, 9/64π = πr^2Simplifying, we get:r^2 = 9/64Taking the square root of both sides, we get:r = 3/8The circumference of a circle is given by the formula C = 2πr, where C is the circumference and r is the radius.Therefore, the circumference of the circle is:C = 2π(3/8) = 3π/4 units

Rewrite 17.9 ÷2.38 so that the divisor is a whole number.

Answers

Answer:

7.52

Step-by-step explanation:

First convert the decimal 2.38 into a whole number by multiplying both the numerator and denominator by 100, since 2.38 can be expressed as 238/100:

17.9 ÷ 2.38 = (17.9 × 100) ÷ (2.38 × 100)

Simplifying the expression gives:

1790 ÷ 238 = 7.52

Therefore, 17.9 ÷ 2.38 can be rewritten as 7.52, where the divisor is a whole number.
