Answer: C (0,0), (-4,0) and (0, -5)
Step-by-step explanation:
Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.
- 7x1 = 7
- 7x2 = 14
- 7x3 = 21
- 7x4 = 28
- 7x5 = 35
In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
<em>The answer is 21.</em>
Well, the average of a sum of number is found by adding each given number and dividing that number by the amount of given numbers.
Example: 5+4+3+8=20
and 20/4 = 5, the average of the numbers
Multiply 1.8 by 8.0 using this format:
1.8
x8.0

1. You could write it as a rate.
5 movies = 75 movies
25 TV sitcoms = x sitcoms
2. Cross multiply:
5x = 1875
3. Divide
x = 375 TV sitcoms
you could do the same thing for the second question
5 movies = x
25 sitcoms = 50 sitcoms
cross multiply:
25x = 250
divide:
x = 10
Answer:
A) Amanda will pay $47.5
B) 0.5
C) $120
Step-by-step explanation:
A) From the graph given, at 45 miles, the total cost of rentage = $142.50
She now splits this cost with 2 of her friends. Thus each of them will pay;
Amount = 142.5/3 = $47.5
So,Amanda will pay $47.5
B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.
Coordinates we pick are;
(0, 120) and (50, 145)
Thus, slope; m = (y2 - y1)/(x2 - x1)
m = (145 - 120)/(50 - 0)
m = 25/50
m = 0.5
C) The equation for the graph will now be; y = mx + c
Where m is slope and c is y - intercept.
Thus;
y = 0.5x + 120
Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.
Thus renting for a day is simply the fixed cost of $120
