Answer:

7/5

Step-by-step explanation:

To determine the proportionality you'll have to multiply the answers by x to get y. In this case 7/5 is the answer.

<u>Calculations</u>

0 x 7/5 = 0

20 x 7/5 = 28

40 x 7/5 = 56

The cost depends upon the number of long distance minutes, m, Amy uses. Write the rule that describes Amy's monthly cost.
Yuri [45]
Minutes(m)              Cost
0                                  20
10                                22
20                                24
50                                30

slope formula:
m = (y1 - y2) / (x1 - x2)
m = (20 - 22) / (0 - 10) = -2/-10 = 1/5 or 0.20

y = (1/5)(x) + 20

The rule that describes Amy's monthly cost is:
m = 1/5x + 20 or m = 0.20x + 20

Where x is the number of minutes spent on the call.

Hi can anyone pls help me in dis math problem!!!!! I will mark u as brainliest
FinnZ [79.3K]

Answer:

See explanation

Step-by-step explanation:

Statement 3 is a lie because the mascot for the Philadelphia Phillies is Phillie Phanatic, not Gritty. Statements 1 and 2 are true because the slope of a line expresses how quickly the y value changes over the course of x, and the y intercept of y=3x-5 is negative because -5 is negative. Hope this helps!

In a parallelogram, two sides are each length 12, and the perimeter is 36, what is the length of the remaining sides?
tankabanditka [31]
P=2a+2b
P=36
a=12
36=2*12+2b
36=24+2b
36-24=2b
12=2b
b=6
So, the length of the remaining sides is 6 each.
