To stay healthy, Emily decided to walk for 4/5 miles everyday. She walked 2/5 mile to work and walked 1/4 mile at lunchtime. How much more does she need to walk after dinner is she wants to meet her target distance?

distance need to walk is 3/20

Step-by-step explanation:

To stay healthy, Emily decided to walk for 4/5 miles everyday. She walked 2/5 mile to work and walked 1/4 mile at lunchtime.

Target distance is 4/5 miles

walked 2/5 miles  and walked 1/4 miles

Total mile walked is

LCD is 20

make the denominators same and add the fractions

Target distance is 4/5 miles

Now subtract the miles walked from targeted distance

so distance need to walk is 3/20

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! : )
