Question
What is the sum of the interior angles of a regular shape witj 6 sides
Solution 1
Regular shape with six sides:  That is a Hexagon

Sum of angles in a regular Polygon is:  (n - 2)*180

Where n = Number of sides

For Hexagon, n = 6.

Sum =  (n - 2)*180

=   (6 - 2)*180 =  4 * 180 =  720°

Question
If SAT scores are normally distributed with a mean of 1518 and a standard deviation of 325, find the probability that a randomly selected SAT score is between 1550 and 1575. A. 0.5714 B. 0.9684 C. 0.0316 D. 0.5398
Solution 1
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575

Z = (X - x_bar)/sigma

Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18

From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714

P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316

Question
What is the equation of the line that passes through the points (0, -4) and (2, 8)? A. y = 6x - 4 B. y = 6x + 4 C. y = 4x + 6 D. y = -4x + 6
Solution 1

m = Y₂ - Y₁ / X₂ - X₁

m = 8 -  (- 4) / 2 - 0
m = 12 / 2
m = 6

So now your equation is y = 6x + b. This eliminates options C and D. Plug in any of your ordered pairs to find b. I picked the first one.

- 4 = 6(0) + b
- 4 = 0 + b
- 4 = b

Your equation is y = 6x - 4.
Question
Write an equation for the line that passes through (0, -9) and (3, 0). A. y = 3x + 9 B. y = -9x + 3 C. y = 3x + 3 D. y = 3x - 9
Solution 1
First find the slope of the line:-

= (0- - 9) / (3 - 0)  =  9/3 = 3

Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)

y = 3x - 9  is the answer   Its D.
Question
A circle with the equation (x + 4)2 + (y - 3)2 = 9 is reflected over the line y = -1. What is the equation of the image? (x - 2)2 + (y - 3)2 = 9 (x + 4)2 + (y - 5)2 = 9 (x + 4)2 + (y + 5)2 = 9 (x - 2)2 + (y + 5)2 = 9
Solution 1
The center of the given circle  = (-4, 3)
So the center of the image  = (-4, 3 -2(4)  =  (-4, -5)

So the equation of the image  is
(x + 4)^2 + (y + 5)^2 = 9

Its  choice 3.
Question
Which of the following equations is non-linear? A. 5x + 1 = -4x + y B. y - 2 = 3x + |-2| C. x + 4y = 2y + 15 - x D. y + 10y - 3 = 2|x| - 4y
Solution 1
Hello!

A line that has the absolute value of a variable is not linear

The answer is D) y + 10y - 3 = 2/x/ - 4y

Question
-2x+4y=-8 which graph models the equation
Solution 1
Hello!

First you have to get the equation into slope-intercept form

Slope-intercept form is y = mx + b

-2x + 4y = -8

4y = 2x - 8

Divide both sides by 4

y = 1/2 x - 2

The graph is a line that goes through the points (0, -2), (-2, -3), (2, -1) and
(4, 0)
