The slope-intercept form of the line passing through points
1) (4,0) and (4,5) is: 0=x-4.
2) (0,-5) and (1,-2) is: y=3x-5
3) (0,1) and (2,-2) is: y=-3/2x+1
4) (-1,0) and (0,-5) is y=-5x-5
Step-by-step explanation:
The standard equation for a slope-intercept form is y=mx+c where m is the slope of the line and c is the y-intercept.
1) The given points are (4,0) and (4,5). The slope is not defined. the y-intercept is 4. The equation of the line is x=4
2) The given points are (0,-5) and (1,-2). The slope is \(\frac{-2+5}{1-0}=3\). the y-intercept is -5. The equation of the line is y=3x-5
3) The given points are (0,1) and (2,-2). The slope is \(\frac{-2-1}{2-0}=-\frac{3}{2}\). y-intercept is 1. The equation of the line is y=-3/2x+1
4) The given points are (-1,0) and (0,-5). The slope is \(\frac{-5-0}{0+1}=-5\). y-intercept is -5. The equation of the line is y=-5x-5

We can match each of the following events with the best description of their probability as follows:
Landing on a number greater than 6 = as likely as not
Landing on the number 0 = unlikely
Landing on an odd number = likely
Landing on a number greater than 2 = Certain
How to determine the probabilitiesTo determine the probabilities, we could first assign the entire numbers to be obtained as 8. Next, we use the statements given to determine the likely probabilities. For instance, the likelihood of getting a number greater than 6 gives us the numbers, 7 and 8.
Now, we sum these up and obtain the probability. This gives us 2/8 which is equal to 0.25. So, it is possible to get a number greater than 6 when the spinner is spun.

through: (-5,3), parallel to x=0
Answers
Answer:
The problem is asking for a line that is parallel to x = 0, and pass though the point (-2;-1). If the line is parallel to x = 0, that means that is a vertical line, because that reference is the y-axis. So, all vertical lines just have one variable, because the only variate in one variable. For a general vertical line, the equation is \(x = k\) , where k is a real number through which the line pass through. If the problem says that the line pass through (-2;-1), then ,k= -2 and the linear equation is x = -2 , that is, a vertical line, parallel to x = 0 and pass through (-2;-1).

x = -5

Y is between X and Z. XZ=3 and XY=1 1/3. find YZ
Answers
Answer:
YZ is 1 2/3
Step-by-step explanation:
The whole thing is 3 units. One part is 1 1/3. Subtract to find the other part. We can change both numbers to improper fractions. Subtract by subtracting the top number (numerator) and just keep the bottom the same.
3 - 1 1/3 =
9/3 - 4/3=
5/3=
1 2/3
Or if you are practicing mental math (no pencil and paper) you can take away the 1 from the 3. Now you have 2 and you still need to subtract 1/3. If you take away 1/3 from 2, there will be 2/3 leftover and another 1 whole untouched. So you get 1 2/3 again!

The proof for the congruence of angles 3 and 4 is given by the image presented at the end of the answer.
What are vertical angles?Vertical angles are angles that are opposite by the same vertex on crossing segments, hence they share a common vertex, thus being congruent, that is, having the same angle measure.
The vertical angles in this problem are listed as follows:
1 and 3.2 and 4.What is the transitive property of congruence?The transitive property of congruence defines that:
If two angles are congruent to a third angle, then the two angles are also congruent between themselves.
Hence the angles that are congruent based on the transitive property of congruence are given as follows:

Step-by-step explanation:
f(x) = -x^2 + 10x - 17
Convert to vertex form by:
f(x) = -(x^2 - 10x) - 17
= - [(x - 5)^2 - 25] - 17
= -(x - 5)^2 + 25 - 17

Find the amount of periodic payment necessary for the deposit to a sinking fund. (Round your answer to the nearest cent.)

A n r t
————————————————————————
$85,000 quaterly 1,4 % 5 yr
Answers
The amount of the periodic payment necessary for the deposit to a sinking fund is approximately $18,065.19.
To find the amount of the periodic payment necessary for the deposit to a sinking fund, we can use the formula for the future value of an ordinary annuity. The formula is:
X = A * (1 + r)^nt / [(1 + r)^nt - 1]
Where:
X is the amount needed
A is the periodic payment
r is the interest rate per period
n is the number of compounding periods per year
t is the total number of years
Given the information:
Amount Needed (X) = $85,000
Frequency: Quarterly
Rate (r) = 1.4% (or 0.014 as a decimal)
Time (t) = 5 years
Since the frequency is quarterly, the number of compounding periods per year (n) is 4.
Substituting the values into the formula:
$85,000 = A * (1 + 0.014)^(4*5) / [(1 + 0.014)^(4*5) - 1]
Simplifying the equation:
$85,000 = A * (1.014)^20 / [(1.014)^20 - 1]
To find the value of A, we can rearrange the equation:
A = $85,000 * [(1.014)^20 - 1] / (1.014)^20
Using a calculator or spreadsheet, we can calculate the value of A.
A ≈ $85,000 * 0.298 / 1.350
A ≈ $18,065.19

The equation of the parabola with vertex at the origin and focus at (-6,0) is given as follows:
y = -1/24x².
How to obtain the equation of the parabola?The y-coordinate of the focus is the coordinate that varies relative to the vertex, hence we have a vertical parabola, with the definition given as follows:
y = a(x - h)² + k.
In which the parameters are given as follows:
a is the leading coefficient.(h,k) are the coordinates of the vertex.The vertex is at the origin, hence h = k = 0, than:
y = ax².
The focus is at (-6,0), hence the leading coefficient a is given as follows:
a = 1/(4 x -6)
a = -1/24.
Then the equation of the parabola is given as follows:
y = -x²/24.

Shannon earned some money doing odd jobs last summer and put it in a savings account that earns 13%interest compounded quarterly. after 6 years there is $700.00 in the account how much did Shannon earn doing odd jobs
Answers
Since the interest rate is 13% compounded quarterly, then an increase of 13÷4 percent is applied each 3 months. In 6 years, there are 24 of such periods.
Let I be the initial amount of money.
Each three monts, the balance gets multiplied by a factor of:
\(1+\frac{13\div4}{100}=1.0325\)Therefore, after 6 years, the balance will be:
\(I\cdot(1.0325)^{24}\)Since after that time, the balance is $700.00, then:
\(\begin{gathered} I\cdot(1.0325)^{24}=700 \\ \Rightarrow I=\frac{700}{1.0325^{24}} \\ =\frac{700}{2.154574\ldots} \\ =324.89 \end{gathered}\)Therefore, Shannon earned $324.89 doing odd jobs.

Why is the straightedge of a ruler not the same as a line?
Answers
Since a straightedge lacks measurement gradients, it can only be used to create or draw straight lines—not to measure length.
An instrument for drawing straight lines or ensuring their straightness is a straightedge or straight edge. It is typically referred to as a ruler if its length is marked with uniformly spaced markings. If no markings are present, it is just a straight edge.
Straight lines can be measured and marked with a ruler. A straight edge won't help you measure, but since they are typically more robustly constructed than rulers, they are a better tool for drawing straight lines. Most of the time, rulers can be used as a straight edge.
