If I spent 2/5 of my monthly salary on my mortgage and had $1200 left over for all my other expenses. How much did I spend on my mortgage?

I spent $800 on my mortgage

Step-by-step explanation:

Proportions

Let's call x=montly salary.

I spent on my mortgage. This leaves

left over for other expenses. That amount of money is given:

Multiplying by 5/3:

x = $2000

My monthly salary is $2000. I spent 2/5 *$2000 = $800 on my mortgage

I spent $800 on my mortgage

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
