Hello,
Shall we begin?
<span>F(x)=9x-6
</span>
F(1) = 9 * 1 - 6
F(1) = 9 - 6
F(1) = 3
Answers: 3
Answer:
No, he is incorrect because he forgot to multiple the negative by the x, and only multiplied 3 by x instead of -3 by x.
Step-by-step explanation:
The correct re-write of this expression is:
-3x - 30
10
sum is add
cube is to the 3rd powr
19+x³
11.
product means multiply
3 times y is no more than (equal to or less than ) 21
3y≤21
no need to solve
12. 2 times difference is 10
difference is subtract
2(z-12)=10
<span>8(-9-5x)
</span>=8(-9) - 8(5x)
= -72 - 40x
= - 40x - 72
expand by using distributive property
hope it helps
