Answer:
EASY PEASY
Step-by-step explanation:
(5x-5)=(4x+10){being corresponding angles}
solve it now by arranging like
5x-4x=10+5
done
and the second is co-interior
Combine like terms:
-12 + 5a - a - 6a + 8a + 8 + 3a

5a - a = 4a
4a - 6a = -2a
-2a + 8a = 6a
6a + 3a = 9a
-12 + 8 = -4
Answer

Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
I think the answer is 1 but I can’t see the picture
