Answer: f(4) = 21
Step-by-step explanation:
2(4)^2-11
4^2 = 16
2(16)-11
Multiply 2 and 16
32 - 11
Subtract

Answer:
- 10 - (-20 + 5)
Step-by-step explanation:

have a nice day and mark me brainliest! :)
Answer:
3x-10+70°=180°(Supplementary angles)
3x+60°=180°
3x=180°-60°
3x=120°
3x/3 =120°/3
x=40°
Step-by-step explanation:
Hope that this is helpful.
Have a wonderful day.
Answer:
y=15
Step-by-step explanation:
The formula for direct variation is
y = kx
5 =k*2
Solve for k
Divide by 2
5/2 = k
y = 5/2 x
Now we substitute x=6
y = 5/2(6)
y = 15
