To find the inverse of a function, you swap the x and y values. So instead of y=4x+8, it becomes x=4y+8. Now you re-solve for y, and that’s your answer:

x=4y+8
x-8=4y
1/4x-2=y
So h(x)=1/4x-2, or the first option

-2(4-x)=12x-3 need help please
olga nikolaevna [1]
-8+2x=12x-3
Subtract 2x from both sides

-8=10x-3
Add 3 to both sides
-5=10x
Divide both sides by 10
-5/10 = x

-1/2= x

Use the cubic model y=3x^3 to find the value of y when x=8
GalinKa [24]

Answer:

Value of y is 1536.

Step-by-step explanation:

We have given an expression y=3x^3

We need to find the value of y when x=8

We will substitute the value of x as 8 in the given expression we get

y=3(8)^3

On simplification we get

y=3(512)

On further simplification we get:

y=1536

Hence, the required value that is the value of y is 1536

Form a sequence that has two arithmetic means between -1 and 59.
9966 [12]

Answer:

Correct choice is B

Step-by-step explanation:

For the numbers -1 and 59, find the difference 59-(-1):

since 59-(-1)=60 and \dfrac{60}{3}=20 (two arithmetic means tells you there will be three intervals), two arithmetic means will be

  • -1+20=19;
  • 19+20=39.

The only correct sequence is -1, 19, 39, 59.

Given (-2, 4) (1, -2). Find the slope of the line
gavmur [86]

Answer:

-2

Step-by-step explanation:

We can find the slope of a line given two points from

m = (y2-y1)/(x2-x1)

    = (-2-4)/(1--2)

    = (-6)/(1+2)

    =-6/3

    =-2
