Solve for y.
1. y= -1/4
2. 1/4.
3. y=41/4.
4.41/25
what is the correct answer?

1. y= -1/4

Step-by-step explanation:

y/5 + 3/10 = (y+2)/7

Get a common denominator for the left hand side

2y/10 + 3/10 = (y+2)/7

(2y+3)/10 = (y+2)/7

Using cross products

(2y+3) *7 = 10*(y+2)

Distribute

14y+21 = 10y+20

Subtract 10y from each side

14y-10y +21 = 10y-10y+20

4y+21 =20

Subtract 21 from each side

4y+21-21 = 20-21

4y = -1

Divide by 4

4y/4 = -1/4

y = -1/4

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! : )
