Answer:
(1,-3) and (-2,0)
Step-by-step explanation:


Applying the second equation to the first

Solving the equation we get

When x = 1

When x = -2

So, the line and curve will intersect at points (1,-3) and (-2,0)
0.04761 would be the answer
Answer:
a = -8
Step-by-step explanation:
-5⁄2 a + 5 = 25
Subtract 5 from each side
-5⁄2 a + 5-5 = 25-5
-5/2 a = 20
Multiply each side by -2/5 to isolate a
-2/5 * -5/2 a = -2/5 *20
a = -8
Find the average :8.4+7.5+12.9+10.6 divided by four
