Janet has $120.if she saves $20 per week, in how many days will she have $500

It will take 133 days for Janet to save the money.

In order to find this, start by finding out how much more she needs to save. To find this, subtract the amount she has from the total goal amount.

500-120 = 380

So we know that she needs $380. To find how many weeks that it, divide the total amount needed to save by the amount she can save a week.

380/20 = 19 weeks.

Now to find the number of days, multiply the weeks by the number of days in a week.

19 x 7 = 133 days

The equation is 120 + 20x=500

19 weeks

positive

step-by-step explanation:

the quadrant is facing upwards

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! : )
