Answer:
Step-by-step explanation:
(2•7)-5
14-5= 9
So the answer is 9
X=58 the exterior angle is “D” 60degrees
Answer:
y=-2
Step-by-step explanation:
The formula for inverse variation is
xy =k
if y=7 when x=-2, we can substitute these numbers in to find k
(-2)(7) =k
-14 =k
The equation becomes
xy = -14
Let x =7
7y = -14
Divide each side by 7
7y/7 = -14/7
y = -2
