Answer:
a = 3
Step-by-step explanation:
The point (- 5, 7a ) satisfies the equation
Substitute the coordinate points into the equation and solve for a
7a = 7(- 5) + 56 = - 35 + 56 = 21 ( divide both sides by 7 )
a = 3
Answer:
5P= 2P+21+45 ( sum of two sides is is equal to
the opposite exterior angle)
5P=2P +61
5P-2P=61
3P=61
p= 61÷3
p=2.33333
The ordered pair is (2,1)
