5x+2y=7
7x-2y=5 its subtract not add
Answer:
see below
Step-by-step explanation:
I enter the equation into a graphing calculator and let it do the graphing.
___
If you're graphing this by hand, you start by looking for the parent function. Here, it is |x|. That has a vertex of (0, 0) and a slope of +1 to the right of the vertex and a slope of -1 to the left of the vertex.
Here, the function is multiplied by -3/2, so will open downward and have slopes of magnitude 3/2 (not 1). The graph has been translated 5 units upward, so the vertex is (0, 5).
I'd start by plotting the vertex point at (0, 5), then identifying points with slope ±3/2 either side of it. To the left, it is left 2 and down 3 to (-2, 2). The points on the right of the vertex are symmetrically located about the y-axis, so one of them will be (2, 2).
Of course, you don't plot any function values for x > 4.
Start by distributing the - 1/3 which is the same as dividing the entire parentheses by 3 which results in (3x+10)
Answer:
t = 5 years
Step-by-step explanation:
I = $ 2000
P = $ 5000
r = 8%

Point A' is at (-2,-2)
Point D' is at (-2,4)
Just multiply each coordinate by 2
