Answer:
(4, 1 )
Step-by-step explanation:
y = 2x - 7 → (1)
y = - x + 5 → (2)
substitute y = 2x - 7 into (2)
2x - 7 = - x + 5 ( add x to both sides )
3x - 7 = 5 ( add 7 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations
substituting into (2)
y = - 4 + 5 = 1
solution is (4, 1 )
Im looking for this answer to lol
(2A)/h -a =b
A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.
2A=h(a+b) Multiply both sides of equation by 2
(2A)/h= a+b Divide both side by h
(2A)/h -a= b Subtract a from both sides
the answer is B
