Given f(x)=7(9−x), what is the value of f(−3) ?

f(− 3) = 84

Step-by-step explanation:

Given the function,  f(x) = 7(9 − x), to find the value of f(-3) substitute x = -3 into the function:

f(− 3) = 7(9 − (− 3))

f(− 3) = 7(9 + 3)

f(− 3) = 7(12)

f(− 3) = 84

Therefore, f(− 3) = 84.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
