2 answers:
Each load will take 3 gallons. Therefore, we can express the amount of water that will be used for x loads using the equation w=3x, where w is how much water you use and x is equal to how many loads there are. We can set up the equation:
w=(3*4)+(3*
)
From there, we can solve
w=12+(3*)
simplifies to
w=12+
w= 12

w=(3*4)+(3*
From there, we can solve
w=12+(3*
simplifies to
w=12+
w= 12

Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
c is 5
the equation for UV is
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D
