Answer:
(5,6)
Step-by-step explanation:
I'm guessing you mean the coordinates for the point where the lines intersect

↝ x-intercept

↝ y-intercept
y = -5
↝
means that the shade/area is below the graph as shown in the first picture.

↝ x-intercept

↝ y-intercept
y = -3
↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.
First picture is first inequality
Second picture is second inequality.
Answer: The ration for 27:71, would be 3/8. Hope this helps!
(1,4) this is because the flip over y axis does not touch the y value but gives the opposite of the x value
3/4(x+21) = 10.5
0.75x+15.75 = 10.5
0.75x = -5.25
x = -7
Hope it helps : )
