Answer:
<em>B) -7x + 7y = -49</em>
Step-by-step explanation:
This is a y=x plot/line shifted by 7 units.
This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.
Answer: x= 2.5, y = 10
Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:

And cross-multiply:

Then solved for x and y:

Answer:
11.75
Step-by-step explanation:
From the question above 8 is the difference of d and 3.75
We are required to find the value of d
d-3.75= 8
d= 8 + 3.75
d= 11.75
Hence the value of d is 11.75
