Answer:
y = 2x
Step-by-step explanation:
(Slope is 2)
Point Slope form:
y - y1 = m(x - x1)
Put in the points and solve:
y - 2 = 2(x - 1)
y -2 = 2x - 2
+2 +2
y = 2x

Step-by-step explanation:
Answer:
12s +3j= 85.95
15s +2j= 93.55
Step-by-step explanation:
First, define the variables:
Let the cost of a shirt be $s and the cost of a pair of jeans be $j.
From the first sentence:
12s +3j= 85.95 -----(1)
From the second sentence:
15s +2j= 93.55 -----(2)
Well, luckily it is apparent that (x-1) is a root because when x=1 the equation is equal to zero. So we can divide the equation by that factor to find the other roots.
(2x^3+9x^2+4x-15)/(x-1)
2x^2 r 11x^2+4x-15
11x r 15x-15
15 r 0
(x-1)(2x^2+11x+15)=0
(x-1)(2x^2+6x+5x+15)=0
(x-1)(2x(x+3)+5(x+3))=0
(x-1)(2x+5)(x+3)=0
So the roots are x= -3, -2.5, 1
