The answer Its 4.5281 ....etc
Y = mx + b. This linear graph passes through A(0,50) and B(10,51)
m = (y₂-y₁)/(x₂-x₁)
m= (51-50)/10-0)
m=(1)(10)
y = (1/x) + b. To find b, you plugin the coordinates of either A or B,
say A(0,50):
50 = (1/10).(0) + b
50 = 0+b and b= 51
Hence the equation is y =0.1x + 50
<u>Answer:</u>
$109.38
<u>Step-by-step explanation:</u>
$12.50 x 4 hours = $50
$12.50 x 4 hours and 45 minutes = $59.38
$50 + $59.38 =
$109.38
A = (B + b)xH : 2
A = (4.5+7.5) x 5 : 2
A = 12 x 5 : 2
A = 60 : 2
A = 30 in²
