Answer:
120
Step-by-step explanation: because you add 20 twice and thts 40 and 40 times 3 is 120
Answer:
y = -1/4x+1
Step-by-step explanation:
First we need to find the slope of the line pictured
(1,4) and (0,0)
m = (y2-y1)/(x2-x1)
= (0-4)/(0-1)
= -4/-1
=4
The perpendicular line has a slope that is the negative reciprocal
-1 /(4)
-1/4
We have a point and a line
y = mx+b where m is the slope and b is the y intercept
y = -1/4x +b
-1 = -1/4(8) +b
-1 = -2+b
Add 2 to each side
b = 1
y = -1/4x+1
Answer:
8x+2
Step-by-step explanation:
Or -8x+2 but i think its 8x+2
