What is the image point of (-6, 9) after a translation left 4 uints and down 1 unit?
1 answer:
Answer:
(-10,8)
Step-by-step explanation:
So our original point is (-6,9).
A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.
A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.
Therefore, the new point would be:

When the number of sessions is equal to 10, the total cost is the same in the two plans
Step-by-step explanation:
Let
y ---> the total cost
x ---> the number of sessions
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
Planet Fitness
we have
The slope is equal to
The y-intercept or initial value is equal to
substitute
----> equation A
Gold's Gym
we have
The slope is equal to
The y-intercept or initial value is equal to
substitute
----> equation B
Equate equation A and equation B
solve for x
therefore
