Y = 40x + 55
not sure bout the last one tho.. sorry :(
QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12
Answer:
1. The equation would be y = -2x + 9
Step-by-step explanation:
To find the line parallel going through the given point, first note that parallel lines have the same slope. This means that in #1, we have a slope of -2 in the original line, therefore the parallel line will also have a slope of -2. Now we can use this and the given point to find the line using point-slope form.
y - y1 = m(x - x1)
y - 1 = -2(x - 4)
y - 1 = -2x + 8
y = -2x + 9
Answer:
x = 9
Step-by-step explanation:
1/4(8x+12) =21
1/4 * 8x = 2x
1/4 * 12 = 3
2x + 3 = 21
21 - 3 = 18
2x = 18
18/2 = 9
x = 9
