Answer:
(x, y) = (80, -68)
Step-by-step explanation:
Subtract the second equation from the first.
(3x +y) -(x +y) = (172) -(12)
2x = 160 . . . . . . . . . simplify
x = 80 . . . . . . . . . divide by 2
y = 12 -x = 12 -80 = -68 . . . . . find y from the second equation
The solution is (x, y) = (80, -68).
Given:
The price of a share of stock in JZMobile was $74 two weeks ago.
Seven weeks ago, the price was $59 a share.
To find:
The linear equation to find the price p of a share of JZMobile w weeks from now.
Solution:
Let, p be the price of a share of JZMobile w weeks from now.
The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).
Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).
The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is
Adding 74 on both sides, we get
Therefore, the correct option is C.
