Answer:
(1,7)
Step-by-step explanation:
SImply replace x by (1) in the expression to find the value of h:
h(1) = 4 (1) + 3 = 4 + 3 = 7
so for x = 1, h is 7 , which is written as: (1, 7)
297 ft squared
find the area of the triangle, which is (bh)/2
(22*7)/2=77
find the area of the rectangle (bh)
22*10=220
add
77+220=297
y = mx + b
m = Slope
b = y-intercept
y = 8x - 2
m = 8
b = -2
y = 1/4x + 6
m = 1/4
b = 6
