Answer:
60
Step-by-step explanation:
Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.
A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.
16a + 20
= 4*(4a+5)
The final answer is 4*(4a+5).

Answer:
Slope = 40
Step-by-step explanation:
Time spent = 70 hours(given)
Fixed charge = $75 (given)
x = Total number of hours (given)
Variable charge = $40 * Total number of hours.
Variable charge = $40x
Fee charged, y = Variable charge + Fixed charge
y = 40x + 75 ($)
The equation of a straight line is given as: y = mx + c
where m = slope
Comparing it with the equation above, m = 40
The answer is b, if you add 6 to both sides you are left with x is greater than or equal to 16, which is not graphed above.
Answer:
1 unit to the right
Step-by-step explanation:
The y-axis is the vertical line and the point (1,-3) is one unit to the right of the vertical line
