Answer:
x = -11.9
Step-by-step explanation:
x + 5.1 = –6.8
Subtract 5.1 from each side
x + 5.1-5.1 = –6.8-5.1
x = -11.9
The answer should be (C):y=(-3/7)x+3 because:
if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:
(0-3)/(7-0) and the slope of the line would be -3/7
then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):
y=mx+b
0=(-3/7)(7)+b
b=3
SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3

40multiplie by w and 24(there is 24 h in a day so ya 24 we will multiply with
w)
