Find the inverse function y=-5x+20

Mathematics
1 answer:
BabaBlast [244]3 years ago
5 0

Answer:

x = -\frac{1}{5} y + 4

Step-by-step explanation:

The inverse function is a function that reverse a given function.

You can follow this procedure:

The given equation is y = -5x +20

First change the position of the x, because is the variable you need.

-5x+20= y

Now substract 20 in both sides of the equation:

-5x+20-20= y-20

Do the necesary calculations

-5x= y-20

Now divide by -5 both sides of the equation to clear X

\frac{-5x}{-5}  = \frac{(y-20)}{-5}

simplify:

x = \frac{(y-20)}{-5}

x = \frac{(y)}{-5}-\frac{20}{-5}

Finally you will get:

x = -\frac{1}{5}y+4

Given the parent function
lozanna [386]

Answer:

Option c is right.

Step-by-step explanation:

Given is a parabola y =x^2

From that transformation is done to get parabola as

y =(0.2x)^2

We find that instead of x here we use 0.2x

i.e. New x = 5 times old x

Hence there is a horizontal expansion of scale factor 5.

We can check with any point also

When y =4, x=2 in the parent graph

But when y =4 , we have x = 10 in the new graph

i.e. there is a horizontal expansion of scale factor 5.

Paladinen [302]

Answer:

$3.70

Step-by-step explanation:

$25.30 = 2P + 4D. p for popcorn and d for drinks

P= $5.25

$25.30 = 2($5.25) + 4D

$25.30 = $10.50 + 4D

-10.50. -10.50

inverse operations

$14.80 = 4D

÷4. ÷4

Inverse operations

$3.70 = D
