Answer:
x-intercept = -6
<h2>y-intercept = -21</h2>
Step-by-step explanation:
x - intercept is for y = 0
y - intercept is for x = 0.
We have y = -2x - 21.
Substitute:
x = 0 → y = -2(0) - 12 = 0 - 12 = -12
y = 0 → 0 = -2x - 12 <em>add 2x to both sides</em>
2x = -12 <em>divide both sides by 2</em>
x = -6
x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5. 5x + 12y = 80 5(4) + 12(5)=80 20+60=80. That is all. I hope that doesn't sound confusing
What seems like like the best real life assumption? I think that's what it's after. 5ft the height of a person, 9ft way taller than a human... etc.
