Use subsiution]
y=-3x+5
subsitute -3x+5 for y in second equation
5x-4(-3x+5)=-3
distribute
5x+12x-20=-3
add like terms
17x-20=-3
add 20 to both sides
17x=17
divide both sides by 17
x=1
now subsitute 1 for x
y=-3x+5
y=-3(1)+5
y=-3+5
y=2
x=1
y=2
Answer:
6
Step-by-step explanation:
The answer is C. 10 units. This is because they have the same y value so they are the same height, and you need to find the distance between -7 and 3. To get from -7 to 0, you add 7, and to get from 0 to 3 you add 3, so 7 + 3 = 10. I hope this helps!
