Answer:
1/5
Step-by-step explanation:
Reciprocal just means flipped you can put any whole number over 1 if it helps to see that
5/1 = 5
Since reciprocal is asking you to flip 5/1 meaning numerator becomes denominator and vice versa you end up with 1/5 being the reciprocal of 5

Answer:
The coordinates of the point b are:
b(x₂, y₂) = (-5, -1)
Step-by-step explanation:
Given
As m is the midpoint, so
m(x, y) = m (-7, -2.5)
The other point a is given by
a(x₁, y₁) = a(-9, -4)
To determine
We need to determine the coordinates of the point b
= ?
Using the midpoint formula

substituting (x, y) = (-7, -2.5), (x₁, y₁) = (-9, -4)

Thus equvating,
Determining the x-coordinate of b
[x₂ + (-9)] / 2 = -7
x₂ + (-9) = -14
x₂ - 9 = -14
adding 9 to both sides
x₂ - 9 + 9 = -14 + 9
x₂ = -5
Determining the y-coordinate of b
[y₂ + (-4)] / 2 = -2.5
y₂ + (-4) = -2.5(2)
y₂ - 4 = -5
adding 4 to both sides
y₂ - 4 + 4 = -5 + 4
y₂ = -1
Therefore, the coordinates of the point b are:
b(x₂, y₂) = (-5, -1)
Answer:
Are 480/40 and 300/25 proportional? Cross products 48025 = 1200 and 300400 = 1200, so their salaries are proportional.
So in conclusion the answer is true.

Answer:
The average rate of change of the cost of a pack is 22 cents per year.
Another name for the average <em>rate of change</em> is <em>slope</em>.
Step-by-step explanation:
The average rate of change of the cost of a pack (
), in monetary units per year, is equal to the change in the average cost of a pack (
), in monetary units, divided by the change in time (
), in years. Then, the average rate of change is:


The average rate of change of the cost of a pack is 22 cents per year.
Another name for the average <em>rate of change</em> is <em>slope</em>.
