Answer:
B. y = |2x| - 2.
Step-by-step explanation:
If we start with y = 2x:
this passes through the origin and has a slope of 2.
y = |2x| means the absolute ( positive) values only, so the part of the line below the x axis is reflected in the axis to form a V shaped graph.
So we have a V shaped graph with the vertex at (0, 0).
Then -2 brings the vertex from (0, 0) to (0 -2) so we get:
y = |2x| - 2.

What is the measure of X , in degrees?
Answer:
71°
Step-by-step explanation:
The angle of x and angle of 109, are supplementary, which means when added they are equal to 180 degrees.
109 + x = 180
x = 180 - 109
x = 71
Answer:
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Step-by-step explanation:

yng true answer po
thank you:)
Answer: p = 24 − 5 q /2
Step-by-step explanation:
Answer:
[tex]p = \frac{ - 5}{2} q + 24[/tex]
Step-by-step explanation:
Let's solve for p:
[tex]2p+5q=48[/tex]
Step 1: Add -5q to both sides.
[tex]2p+5q+−5q=48+−5q[/tex]
[tex]2p=−5q+48[/tex]
Step 2: Divide both sides by 2.
[tex] \frac{2p}{2} = \frac{ - 5q + 48}{2} [/tex]
[tex]p= \frac{ - 5}{2} q+24[/tex]

OC.
y = 40 + 12
OD.
y = -43 + 20
PLEASE SOMEONE ANSWER ASAP
Answer:
y = - 4x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (4, - 4) into the partial equation
- 4 = - 16 + c ⇒ c = - 4 + 16 = 12
y = - 4x + 12 ← equation of line

What is the surface area of the prism?
Answer:
Step-by-step explanation:
122
Answer:
125.254..
Step-by-step explanation:
The triangles are 8 inches squared each, since it gives the length and width.
Since there are two triangles, it is 16.
The bottom is 4 by 8, which is 32, the back rectangle is 4 x 8 also, which is 32.
So we now have 32 + 32 + 16.
= 64 + 16
= 80
There is that last slant rectangle, which is harder.
We need to use pythagorean theorum to find that slant length first.\
4 ^ 2 + 4 ^2 = x ^2.
16 + 16 = 32.
32's squared root is something like 5.65685424949, but we will use 5.66.
Multiply that by 8 to get 45.254........
Add 80 + 45.254 = 125.254...

The Smith's 5 children need to be lined up for a family photo. In how many ways could this be done? 5 5 5! 5! 5C5 5 cap c sub 5 55
Answer:
120 ways
Step-by-step explanation:
To line 5 children up in a family photo, the number of possible arrangements is obtained by taking the factorial of the number of people on the line.
In this scenario, we have 5 ;
Recall;
n! = n(n-1)(n-2)(n - n-1)
5! = 5(5-1)(5-2)(5-3)(5-4)
5! = 5 * 4 * 3 * 2 * 1
5! = 120 ways

Find the values of x and y that make these triangles congruent by the HL Theorem.
Answer:
x = 3 ; y=2
Step-by-step explanation:
to simplify the work we can build a system of two equations
2x+3 = 3y+3
x = y+1
we can now substitute the value of x in the first equation
2(y+1)+3 = 3y+3
2y + 2 + 3 = 3y+3
2y + 5 = 3y+3
y = 2
now we can subisitute the value of y in the first equation
x = 2 + 1 = 3
Verify
2(3)+3 = 6+3 = 9
3(2) + 3 = 6 + 3 = 9

2+1 = 3

Find y to the nearest degree. *
Step-by-step explanation:
.....................
What are the solutions of the equation?
y=-7(x-3)(x+4)
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4
State the x- and y-intercepts of each equation
15x + 20y = 1,800
