Answer:
a = 8; b = -9
Step-by-step explanation:
Filling in the given values gives you two equations.
7 = a(2) +b
-1 = a(1) +b
Subtracting the second equation from the first gives ...
(7) -(-1) = (2a +b) -(a +b)
8 = a . . . . . simplify
Using this value in the first equation gives ...
7 = (8)(2) +b
b = 7 -16 = -9
The constants are a = 8, b = -9.

Answer:
Height is 7m
Step-by-step explanation:
B = 10 feet area = 35 feet 2 Find the height of the triangle.
Area of triangle = 1/2 b×h
35 = 1/2(10×h)
35 × 2 = 10h
70 = 10h
h = 70/10
h = 7m
