Answer:
A) y= 40x+100
B) 
Step-by-step explanation:
To solve this, we can set up an equation using y=mx+b.
'b' is the initial cost, whereas 'm' is the monthly cost. This gives us the equation:
A): y=40x+100.
For part B, we can solve for the inverse by switching the x and y. This gives us:
x= 40y+100
Now, continue simplifying to isolate the 'y' on a side:
x-100=40y

Answer:
18/23
Step-by-step explanation:
36/46
then simplified to 18/23
If you divide how many total seconds she got off in each game by its penalty, you will see this:
-35 - (-7) = 5
-25 - (-5) = 5
35 divided by 7 is 5, and 25 divided by 5 is 5.
The amount of penalties Yolanda received is equal.
Answer:
A
Step-by-step explanation:
Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate
The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
