Answer:
100.00?
Step-by-step explanation:
if all of them were correct then it should be a 100
Y=5x-1
-15x-3y=3
-15x-15x+3=3
-30x=0
x=0
therefore y=5x0 -1= -1
so one solution(0,-1)
Answer:
15 sides
Step-by-step explanation:
with regular polygons it is best to work with the exterior angles since the sum of exterior angles is 360 degrees
one exterior angle = 180 − one interior angle
∴ one ext. < = 180 − 156
= 24 degrees
no of sides = 360
/24

Answer:
A. √32y²/72x²= 32y/72x
Step-by-step explanation:
√32y²/72x²= 32²/72²
= 32/72.
B. √125m³/36m²
=4192.6/108
=38.8203.
C. √x²/y²-y²/x²
therefore, x²=1, y²=-1
that is, √1/-1 - -1/1= -1(-)-1=0.
Answer:
(4,1)
Step-by-step explanation:
Using substitution you can determine that 2*4-7 is in fact equal to 1
