Answer:
m = -35/49
c = -48
y = -35/49 x - 48
Step-by-step explanation:
Given the coordinate point
(-98, 22), (0, -48)
Slope m = y2-y1/x2-x1
m = -48 - 22/0 -(-98)
m = -70/98
m = -35/49
Substitute m = -35/49 and (0, -48) into the equation y = mx+c
-48 = 0(-35/49) + c
-48 = c
c = -48
Hence the y-intercept is -48
Get the equation
Recall that y = mx+c
y = -35/49 x - 48
Answer:
a = 3, b = -1
Step-by-step explanation:
a = 5b + 8
a = -10b - 7
5b + 8 = -10b - 7
Add 10b from both sides;
15b + 8 = -7
Subtract 8 from both sides;
15b = -15
Divide both sides by 15;
b = -1
Lets substitute b;
a = 5b + 8
a = 5(-1) + 8
a = -5 + 8
a = 3
Answer: E. 2
Step-by-step explanation:
x²=9
x=±3 ⇔ since it is square (any value after square will always be positive), the value can be negative or positive.
There are 2 solutions: 3 and -3
Hope this helps!! :)
Answer:
The original side length of the square was 9 ft
Step-by-step explanation:
Consider that the square was initially of side length "x" (our unknown). Then the sides were all increased by 5 ft, and now the perimeter (addition of all four sides) of the square render 56 ft.
Let's write an equation that represents the addition of the four sides of this new rectangle, and set it equal to 56 ft. Then solve for the unknown "x":

Therefore, the original side of the square was 9 ft.
