What is the inverse of the function f(x) = 2x - 10?

1 answer:

6 0

F(x)=2x-10

y=2x-10

x=2y-10

x+10=2y-10+10 (add both sides by 10)

2y=x+10

2y/2=x+10/2 (divide both sides by 2)

y=1/2x+5

Final Answer: f^-1(x)=1/2x+5

Answer:

335.5 in^2

Step-by-step explanation:

The area is a rectangle and a triangle

The area of the rectangle is

A = a*b where a is 11 and b is 25

A = 11*25 =275

The area of the triangle is

A = 1/2 b*h where b is 11 and h is 11

A = 1/2 (11) * 11

A = 60.5

The total area is 275+60.5=335.5

What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) 7x2 + 5x 7x2 + 11x 11x2 + 5x 11x2 + 11x

Anuta_ua [19.1K]

we have

$(9x^{2}+8x)-(2x^{2}+3x)$

Step 1

Eliminate the parenthesis

$(9x^{2}+8x)-(2x^{2}+3x)=9x^{2}+8x-2x^{2}-3x$

Step 2

Group terms that contain the same variable

$9x^{2}-2x^{2}+8x-3x$

Step 3

Combine like terms

$7x^{2}+5x$

therefore

the answer is

$7x^{2}+5x$
