Answer: 2^3 * 5^2.
Exclamation: Since 2 is multiplied out three times, you have 2 to the third power. Same goes for the five- since it’s there twice, that’s 5 to the second power. That brings us to 2^3 * 5^2
Tires:
65(2) - 45(2) = 130 - 90 = $40 profit
Rims:
126(3) - 85(3) = 378 - 255 = $123 profit
Headlights:
15(5) - 5(5) = 75 - 25 = $50 profit
Total profit:
$40 + $123 + $50 = $213 profit
I hope this helps you
5×(3-2)=5×1=5
or
5×(3+(-2))
5×3+5×(-2)
15+(-10)=15-10=5
For a line to be perpendicular to a reference line, it must have a slope that is the negative reciprocal of the reference line's slope, mathematically:
m1*m2=-1, where m1 and m2 are the slopes of the perpendicular lines for them to be perpendicular. In this case, the slope of the reference line is 3/4 so:
3m/4=-1
3m=-4
m=-4/3
So the perpendicular line will have a slope of -4/3, then the line is currently:
y=-4x/3+b, we can solve for b using the point that we must pass through.
-2=-4(-6)/3+b
-2=8+b
-10=b, so our perpendicular line is:
y=-4x/3-10 or more neatly in my opinion:
y=(-4x-30)/3
