Answer:
y = ½x - 11
Step-by-step explanation:
The equation of the line that goes through (8, -7) and is parallel to -2x + 4y = 100, will have the same slope as the line, but different y-intercept (b).
Let's find the slope of -2x + 4y = 100 by rewriting in the slope-intercept form.
-2x + 4y = 100
Add 2x to both sides
4y = 2x + 100
Divide both sides by 4
y = 2x/4 + 100/4
y = ½x + 25
The slope of the given line is ½. Since the line that goes through (8, -7) is parallel to -2x + 4y = 100, therefore the slope (m) is also ½.
To find the y-intercept (b), substitute m = ½, x = 8, and y = -7 into y = mx + b.
-7 = ½(8) + b
-7 = 4 + b
-7 - 4 = b
-11 = b
b = -11
Substitute m = ½ and b = -11 into y = mx + b to get the equation of the line that is parallel to -2x + 4y = 100.
y = ½x + (-11)
y = ½x - 11
Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486
Answer:
sq root of 58
Step-by-step explanation:
-19.35 + 15x
In order to get this answer distribute the 3 to the -6.45 and the 5x.
8m+3
Because sum means adding so you add 8m and 3
