Answer:
9: D 10: A
Step-by-step explanation:
Answer:
SUPER SIMPLE =
if r//s then the two angles which in this case are 110 and 80 should be equal but clearly in this case are not so the the lines r and s arent parallel to each other .
Answer:
x=10
Step-by-step explanation:
I guess solve for x
5x=50
x=10
The first one can be written as a fraction because it is a repeating decimal.
The second one can be written as a fraction because it is a repeating decimal.
The third one can not be written as a fraction since it is nether terminating nor repeating.
The last one can be written as a fraction since it is a terminating decimal.
Answer:
y+21 = -4(x-7)
Step-by-step explanation:
well first you need to find slope what is y2-y1 over x2-x1
23-(-21) ----> 23+21 = 44
-4 - 7 ---> -4 + -7 = -11
so it 44/-11 = -4 is the slope
now choose one pair of points like 7 , -21 and plug them in
y-y1 = m(slope)(x-x1)
so it be y+21 = -4(x-7)
also remember two negatives = a postitive
