Find the discount price and subtract from the total to find the sale price.

To find the discount price, multiply 90 b 40% (convert 40% into decimal)

90 x 0.4 = 36

Next, subtract the discount from the total to find the sale price.

90 - 36 = 54

So, the sale price is <u>$54</u>.

Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8

Klio2033 [76]

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

$f(x)=-x^2+1$ $for$ $x =3-9$ $4-4-8$

Simplify 4−4−8 to substitute in f(x)=−x^2+1

Subtract 4 from 4

$0-8$

Subtract 8 from 0

$-8$

Replace the variable x with −

8 in the expression

$f(-8)=-(-8)^2+1$

Simplify

$f(-8)=-64+1$

$f(-8)=-63$

Answer = -63

How do you write the equation 4x + 2y = 16 in function form? Please answer with an explanation!

kramer

F(x)=-2x+8 This is because f(x) is the same as writing y so therefore you have to change the equation to 4x+2y=16 so you have Y=-2x+8
