Answer:
17
Step-by-step explanation:
QS and RS equal the same
5x - 8 = 3x + 2
-3x +8 -3x +8
2x = 10
x = 5 you would then plug x into QS
5(5) - 8
25 - 8

Answer:
x = -4, v = 2.5
x = -14, v = -2.5
Step-by-step explanation:
I am a bit confused with the beginning part of the question. From what I understand, you are trying to solve for x and then plug x into the top equation to find the value for V. I am sorry if that is not what you are looking for. If it is, look below!
x + 9 = 5
x = 5 -9
x = -4
v(x + 9)2 = 25
v(-4 + 9)2 = 25
v(5)2 = 25
v(10) = 25
v = 25/10
v = 2.5
x + 9 = -5
x = -5 -9
x = -14
v(x + 9)2 = 25
v(-14 + 9)2 = 25
v(-5)2 = 25
v(-10) = 25
v = 25/(-10)
v = -2.5
I hope this helped! If not, I am sorry. :(
Answer:
Step-by-step explanation:
A function is odd if f(-x) = -f(x)
A function is even if f(-x) = f(x)
And neither if neither are true.
In this case if we plugged in a negative x here
f(-x) = (-x)^3 - 11(-x)
f(-x) = -x^3 + 11
Therefore, this function is odd because if we pulled out a negative one again we would get back the original function. Or in other words f(-x) = -f(x) for f(x) = x^3 - 11x

Answer:
140
Step-by-step explanation:
Angle 4 is congruent to angle 2 by corresponding angles postulate. Therefore, angle 2 is also 40. Angle 2 and angle 3 are supplementary, or add up to 180 because they are on a straight line. 140 and 40 add up to 180 so angle 3=140 degrees
