In order to find the area, you multiply the width (7), height (6) and length (12). But the problem states that the height has changed from 6 to 6 minus3, which would be 3. So you multiply 3, 7, and 12.
I am not sure but wouldn't it be y=3x-6 and y=4x-7
Slope is rise over run or
(y1-y2)/(x1-x2)
(x,y)
x1=17
x2=-11
y1=-6
y2=7
slope=(-6-7)/(17-(-11))=(-13)/(17+11)=(-13)/(28)=
the slope is -13/28
Answer:
x = 10
Step-by-step explanation:
3x + 55 = 9x - 5 (add 5 to both sides)
3x + 55 + 5 = 9x - 5 + 5
3x + 60 = 9x (subtract 3x from both sides)
60 = 9x - 3x
60 = 6x (rearrange)
6x = 60 (divide both sides by 6)
x = 60/6
x = 10
