A(x) = (11+x)(7+3x)
A(x) = 77 + 33x + 7x + 3x^2
A(x) = x^2 + 40x + 77

Find the slope of the line.<br> 9x+y=9
Serggg [28]

Answer: -9/1

Step-by-step explanation: you want to get x and y on opposite sides so you subtract 9x and that gives you y=-9x+9 because the nine on the right side doesn’t have a negative in front of it so you know it’s positive. Your slope is whatever comes before the x so since it’s -9 that means it’s -9/1

What is the quotient?
AlexFokin [52]

Answer:

3/2

Step-by-step explanation:

● (-3/8) ÷(-1/4)

Flip the second fraction by putting 1 instead 4 and vice versa.

● (-3/8)* (-4/1)

-4 over 1 is -4 since dividing by 1 gives the same number.

● (-3/8)*(-4)

Eliminate the - signs in both fractions since multiplying two negative numbers by each other gives a positive number.

●( 3/8)*4

● (3*4/8)

8 is 2 times 4

● (3*4)/(4*2)

Simplify by eliminating 4 in the fraction.

● 3/2

The result is 3/2
