Answer:
x=33
Measure of angle 5=81
Measure of angle 6=99
Measure of angle 7=81
Measure of angle 8=99
Step-by-step explanation:
Angles 7 and 8 are supplementary because they share a common vertex while laying on a line.
That is the measurement of angles 7 and 8 add up to be 180.
mAngle7+mAngle8=180
(2x+15) + (3x ) =180
2x+15 + 3x =180
Combine like terms:
5x+15 =180
Subtract 15 on both sides:
5x =180-15
Simplify right hand side:
5x = 165
Divide both sides by 5:
x =165/5
Simplify right hand side:
x =33
The measure of angle 7 is 2x+15=2(33)+15=66+15=81.
The measure of angle 8 is 3x=3(33)=99.
Recall vertical angles are congruent.
5 and 7 are vertical so the measure of angle 5 is 81.
6 and 8 are vertical so the measure of angle 6 is 99.
Measure of angle 5=81
Measure of angle 6=99
Measure of angle 7=81
Measure of angle 8=99

Rounding to the nearest cent is about 46 cents per donut.
Answer:
y = 10x-37
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 10x+b
Substitute the point into the equation
3 = 10*4+b
3 = 40+b
Subtract 40
3-40 = 40+b-40
-37 = b
y = 10x-37
Answer:
you would save 11.51 dollars
Step-by-step explanation:
12 cans times the vending machine price of 1.25$= $15
15-3.49=11.51
Answer:
(B). F(X)=2x^2+2x-4
Step-by-step explanation:
-4 means it passes through -4 at the y axis
B and D have -4
graph passes thru x axis at -2 and 1
if you enter x = -2 or 1 in the formula
(B). F(X)=2x^2+2x-4
you get 0
it's not D because when you enter -2 or 1 for x
you don't get 0
you get 8 and -4
