Answer:
see the explanation
Step-by-step explanation:
step 1
Find the scale factor of the dilation
Divide the x-coordinate or the y-coordinate of the image by the the x-coordinate or the y-coordinate of the pre-image
so
![\frac{-6}{-4}=1.5](https://tex.z-dn.net/?f=%5Cfrac%7B-6%7D%7B-4%7D%3D1.5)
or
![\frac{9}{6}=1.5](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B6%7D%3D1.5)
step 2
Multiply the coordinates of point B by the scale factor to obtain the image B'
B'(1.5*1,1.5*4)
B'(1.5,6)
Answer:
18
Step-by-step explanation:
Since he does 90 cars-----5 days
x cars--------1 day
we multiply 90 by 1 then over 5
Answer:
see below
Step-by-step explanation:
Since this is written in vertex notation the vertex is (4, 60). The axis of symmetry is equal to the x - coordinate of the vertex which is the vertical line x = 4.
Hello!
your three answers are:
the maximum height of the rock occurs at x=0 because the y intercept always is at x=0, and the starting point is the y intercept
the rock is in the air for 3 seconds because x goes to a max of 3
the maximum height of the rock is 45 feet because y, or height, starts at 45, and ends at 0
I hope this helps, and have a nice day!
The least amount Brenda can pay each month is $73.
Step-by-step explanation:
Given,
Amount owed by Brenda to school = $438
Time to pay off = 6 months
Let,
x be the amount Brenda can repay in 1 month.
Time period*Amount each month ≥ Total amount
![6x\geq 438](https://tex.z-dn.net/?f=6x%5Cgeq%20438)
Dividing both sides by 6
![\frac{6x}{6}\geq \frac{438}{6}\\x\geq 73](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%5Cgeq%20%5Cfrac%7B438%7D%7B6%7D%5C%5Cx%5Cgeq%2073)
The least amount Brenda can pay each month is $73.
