Let's plug in the variables one by one.
6g - 2h
plug in 5 for g and 4 for h
6(5) - 2(4)
multiply
30 - 8
subtract
→ 22
20g
plug in 2 for g
20(2)
multiply
40
2(g + 1)
plug in 10 for g
2(10 + 1)
add
2(11)
multiply
→ 22
4g + 5h
plug in 1 for g and 4 for h
4(1) + 5(4)
multiply
4 + 20
add
24
Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)
Answer:
Its -12 if a is meant to be multiplied
Answer:
70 is answer
Step-by-step explanation:
Given that a function in x is
we have to find f'(7)
we know by derivative rule derivative of a function is
For finding out at 7 we replace x by 7
=
So f'(7) = 70
answer is 70
