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
Answer: y = —
x + 3
Step-by-step explanation:
The line crosses the y-axis at the point (0,3), making its y-intercept be +3.
The line is going downwards left to right, giving it a negative slope.
The line's slope is — because it is negative and it goes down 1, over 2.
Therefore, the line's equation is y = — x + 3
Answer:
79200 feet is the volume of great wall.
Step-by-step explanation:
1 mile = 5280 feet
5280 feet × 15 feet = 79200
The height is the thing that we don't need to use, because you need volume, volume is the place where the wall at, the place is 79200 feet.
And I have question for you, have you ever go to China, did you go to the great wall, where did you come from.
