At one store,5 pairs of jeans and 2 sweatshirts cost $208,while 3 pairs of jeans and 4 sweatshirts cost $178.Find the cost of one sweatshirt.

$19

Step-by-step explanation:

the following equations can be determined from the question

5j + 2s = 208 equation 1

3j + 4s = 178  equation 2

where j = jeans

s = sweatshirts

simultaneous equation would be used to determine the values

Multiply equation 1 by 2

10j + 4s = 416 equation 3

subtract equation 2 from 3

7j = 238

j= $34

substitute for j in equation 1

5(34) + 2s = 208

2s = 38

s = $19

f is the midpoint of

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! : )
