The answer to the problem is 119.9
Move the decimal 2 places to the right
8.4 becomes 840
Y-intercept (7,0) x-intercept (0,14) = f(x)= -2x+14
He has a total of 40
$40-$5-$15=$20
he has a total of $20 left

4a + 2b = 10
you are solving for b
isolate the b
subtract 4a from both sides
4a (-4a) + 2b = 10 (-4a)
2b = 10 - 4a
divide 2 from both sides to isolate the b
2b(/2) = (10 - 4a)/2
b = (10 - 4a)/2
b = 5 - 2a
C) b = -2a + 5 is your answer
hope this helps
