Trust me on this, The answer could only be 15 when solving for b. Hopefully that helps.
Answer:
38.4;
Step-by-step explanation:
32.5% × ? = 12.48
? =
12.48 ÷ 32.5% =
12.48 ÷ (32.5 ÷ 100) =
(100 × 12.48) ÷ 32.5 =
1,248 ÷ 32.5 =
38.4;
The path of the car and the limo are straight lines.
To determine the equation of the lines of the paths, the slopes must be determined.
Let m1 = slope of car
m2 = slope of limo
so,
m1 = (7 + 7)/(5 + 2) = 2
m2 = (-5 -9)/(3+4) = -2
therefore the equations are
car:
2x – y = 2(5) –(7)
2x – y = 3
Limo:
2x + y = 2(3) – 5
2x + y = 1
Solving the intersection of the equations (using a calculator)
x = 1
y = -1
