1) h(x)=3x3 g(x)= - 4x+1 Find (h+g)(10)

Aleksandr-060686 [28]

Answer:

$(h+g)(10) = 2691$

Step-by-step explanation:

$h(x) = 3x^3\\g(x) = -4x+1$

Adding both equations will make it:

$(h+g)(x) = 3x^3-4x+1$

Putting x = 10 will make it:

$(h+g)(10) = 3(10)^3-4(10)+1$

= 3(1000)-40+1

= 3000-39

= 2961

7 - 8x + 22 What does X equal! x =?

VashaNatasha [74]

Answer: x = -3.625 or -29/8

Step-by-step explanation:

7-8x+22

1. -Set it equal to 0.

7-8x+22=0

2. Subtract 7 and 22 from both the left and right sides.

7-8x+22=0

-7 -22 -7 -22

8x = -29

4. Divide both sides by 8.

8x=-29

8 8

x= -3.625

Leave it in fraction form if decimal is unacceptable.

hope this helps.
