Find the inverse.

Answers

Answer:

The inverse of this equation would be f(x) = x/-4

Step-by-step explanation:

In order to find any inverse, start by switching the x and f(x) values. After doing this, you can solve for the new f(x) value and that will be your inverse.

f(x) = -4x

x = -4f(x)

x/-4 = f(x)

f(x) = x/-4

the area of a rectangle is given by 6x²+19x+15. if x represents 4m, what are the dimensions of the length and width of the rectangle?

Answers

Answer:

Length = 17m

Width = 11m

Step-by-step explanation:

Expression for the area of the rectangle = 6x² + 19x + 15

Factorising the quadratic expression

6x² + 19x + 15 = (6x² + 9x) + (10x + 15) = 3x(2x + 3) +5(2x + 3) = (3x + 5)(2x + 3)

x = 4m

Length = 3x + 5 = 3(4) + 5 = 12 + 5 = 17m

Width = 2x + 3 = 2(4) + 3 = 8 + 3 = 11m

Gary earned a gross pay of $1,047.30 last week. Using the fact that Social Security tax is 6.2% of gross pay, determine the amount of Social Security tax deducted from Gary’s gross pay.

Answers

SS tax is 6.2% of 1,047.30

In math "of" means times, so

.062 x 1047.30 = 64.9326

put this function into standard form

Answers

Answer:

It is already in standard form. $2x^2-7x-15$ is correct.

Step-by-step explanation:

The standard form of a quadratic equation (which this equation is since there is an $x^2$ term) is described as $ax^2+bx+c=0$ , where a≠0.
