Answer:
Step-by-step explanation:
Let x represent the number of video games that Kevin rents.
Let y represent the total amount that he paid for x video games rental.
The slope intercept form of an equation is expressed as
y = mx + c
Where
m = slope
c = intercept
When Kevin rented 2 games, he had spent a total of $25 of his money. When Kevin rented 2 more video games (4 total), he then had spent $30 total of his money at this store all together. Therefore,
Slope, m = (30 - 25)/(4 - 2) = 5/2 = 2.5
To determine the intercept, c, we will substitute m = 2.5, x = 4 and y = 30 into y = mx + c. It becomes
30 = 2.5 × 4 + c
30 = 10 + c
c = 30 - 10 = 20
The Slope-Intercept Form to model how much Kevin pays per x video game rentals with his store membership becomes
y = 2.5x + 20
The cost per video game rental is $2.5
The membership fee is $20
Answer:
well they are each a part of each other on numerator is 10 because 10 across
the other is 3 because its 3 down. right?
Step-by-step explanation:
Answer:
y=2.5x
Step-by-step explanation:
To get the equation in y = mx + b format, we need to find m and b, the slope and y-intercept.
To find the slope, we need two points on a graph, which we have.
First, the slope
The formula for slope is
Our points, (6, 15) and (2, 5)
Plugging into our equation:
, which is 10 divided by 4, which is 2.5
Our equation now:
To find our b, we need to plug in one x value.
(6, 15) are our pair of points.
6 = x
15 = y
=>
=>
If b is 0, then we don't need to include b.
Our equation is 
the outlier is 37 it affects the mean because
1)37+4+ 7+ 3 +11 +9+13+ 5=89
2)89 divide by 8 number= 11.1 , it give you a decimal number
The measure of AEC is 115°.
AED and AEC are supplementary, meaning AED + AEC = 180°
AED + 65° = 180
AED = 115°
