Answer:
Distance = -7.6
Step-by-step explanation:
Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)
√((-7 - 0))^2 + (-3 - 0)^2) = 7.6
I think it’s 6. I feel like 6 would be the the correct 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
