Mary jogged from Point P to Point Q while Wyatt jogged from Point Q to Point P.
Point P and point Q are 7.5 kilometers apart.
Mary’s motion is represented by d = 8t and Wyatt’s motion is represented by 2d + 14t = 15, where t hours is the time and d kilometers is the distance from point P. Solve for linear equations. When did Mary and Wyatt meet? minutes later
How far from point Q did they meet? km

When did Mary and Wyatt meet? 0.5 minutes later

How far from point Q did they meet? 3.5 km

Step-by-step explanation:

Mary’s motion is represented by d = 8t----(1)

Wyatt’s motion is represented by 2d + 14t = 15----(2)

We solve for d in equation (2) to get:d=7.5-7t----(3)

We equate equation (1) and (3) to get:

We now solve for t to get:

Now put t=0.5 into equation (1) to get d=0.5*8=4

This means they met 4 km from point P.

Therefore they meet 7.5-4=3.5km from point Q

you should at least use a calculater

step-by-step explanation:

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! : )
