Part a.
w=3.5t+8
w=3.25t+24

how do i solve these step by step? ?

t = 64 and W = 232

Step-by-step explanation:

W = 3.5t + 8

W = 3.25t + 24

If W equals an expression, and W equals another expression, the two expressions must be equal.

Since W = 3.5t + 8 and W = 3.25t + 24, using the substitution property of equality, you get

3.5t + 8  = 3.25t + 24

Subtract 3.25t from both sides.

0.25t + 8 = 24

Subtract 8 from both sides.

0.25t = 16

Divide both sides by 0.25.

t = 64

Now substitute 64 for t in the first original equation to find W.

W = 3.5t + 8

W = 3.5(64) + 8

W = 232

t = 64 and W = 232

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.
