Ok so we have the parabola at origin of y=-12 and crosses x-axis at points x=1,8 so, we could just look at where it crosses the x-axis and find it directly from there. it crosses x-axis at 1 and 8 so the answer can only be A to fit this criteria
36 x 25%
36 x .25
36 x .25 = 9.00
36 - 9.00
36 - 9.00 = $27
C. $27.00
Answer:2X35=70 2X65=130 130-70=60 So 60 dollars profit for the two tires.
3X75=225 3X136=408 408-225=183 So 183 dollars profit for the three rims
5X4=20 5X15=75 75-20=55 So 55 dollars profit for the headlights.
Total profit 60+183+55=298

Answer:
Jo's age = x = 8 years
Step-by-step explanation:
Let
Jo's age = x
Jo's mother, Anne's age = 4x
In four years time, Anne will be three times as old as Jo.
Jo's age =3( x + 4)
Jo's mother, Anne's age = 4x + 4
How old is Jo?
Equate Jo's age and his mother's age
3(x + 4) = 4x + 4
3x + 12 = 4x + 4
3x - 4x = 4 - 12
-x = - 8
Divide both sides by -1
x = 8
Therefore,
Jo's age = x = 8 years
Answer:
A
Step-by-step explanation:
There are 1000 mm in one meter
and there are 10 mm in one cm
so
1000 + 20(10) = 1200mm
Therefore the answer is 1200mm
