Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Rotatation could be done to left or right.
110 + 60 = 170 degrees => Rotation to the right side.
110 - 60 = 50 degrees= > Rotation to the left side.
We can see in the choices that 170 degrees is the right choice.
The answer is D.
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.
f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
Answer:
u = 1.5
Step-by-step explanation:
5+4u=11
-5 -5
4u = 6
/4 /4
u=1.5
