y=2X-5 and 4X-Y=7
Putting the value of Y in 2nd equation:
4x-2x+5=7
2x=7-5
2x=2
OR,x=2/2=1
putting the value of x in equation 1:
y=2x-5
y=2*1-5
y=2-5
y=-3
The answer is G
Hope this helps
To find the volume of something, you do the area times the height. In this case you already know the volume so you solve it like this:
(x represents the height since you don't know the value)
1440= 144 * x
1440 = 144x
1440/144= 144x/144
10 = x
Your height is 10:)
The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.
