Answer:

» Answer: The third objective

${ \tt{h(x) = - 4x + 1}}$

• make x the subject:

${ \tt{h(x) - 1 = - 4x }} \\ \\ { \tt{x = \frac{h(x)}{ - 4} - \frac{1}{ - 4} }} \\ \\ { \tt{x = - \frac{h(x)}{4} + \frac{1}{4} }}$

• Therefore, f(x):

${ \boxed{ \boxed{ \tt{ \: \: f(x) = - \frac{1}{4}x + \frac{1}{4} \: \: }}}}$

-x^(2)-12=-87 Please explain your answer, and how I make the x positive

spayn [35]

Solve for x over the real numbers:
-x^2 - 12 = -87
Add 12 to both sides:
-x^2 = -75
Multiply both sides by -1:
x^2 = 75
Take the square root of both sides:
Answer: x = 5 sqrt(3) or x = -5 sqrt(3) both Answers are correct

Answer:

24x + 41

Step-by-step explanation:

Distribute the 6.

6(4x + 5) + 11 = 24x + 30 + 11
