Answer:
-23x = 7
Step-by-step explanation:
-3x - y =0
×5. ×5 ×5
-15x -5y = 0
-8x +5y = 7
-15x -5y -0
-23x = 7
Given:
Circular racetrack with a diameter of 1/2 mile
Find: how far does a car travel in one lap around the track?
We need to find the circumference of the racetrack.
Circumference is multiplying pi to the diameter of the racetrack.
Circumference = 3.14 * 1/2 mile
Circumference = 3.14/2 mile
Circumference = 1.57 miles rounded to the nearest tenth is 1.60 miles.

Answer:
Second table.
Step-by-step explanation:
A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.
The additive rate of change is determined using the slope formula,

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.
The additive rate of change of this table is

Therefore the second table has an additive rate of change of 3.
