Consider this graph of a line that passes through the points (0,0) and (5,30)
Which equation represents the cost of a phone call, c, in cents, after m minutes, according to the payment plan?
A. c=1/6m
B. c=6m
C. c=1/30m
D. c=30m
Answers
Answer:
B
Step-by-step explanation:
Slope equals rise over run so the slope of this line is 30/5 or 6. That means for every minute calling you would have to pay 6 cents which is shown in the equation c=6m.
the slope of the line represents the rate of the plan and can be calculated by using the change in y values divided by the change in x values of two points on the line. In this case, it would be easiest to pick 0 and 6 as y values, and 0 and 1 as x values. then,
slope = (6-0) / (1-0)
slope = 6/1
slope = 6
therefore the slope is 6 and the correct equation is B: c=6m

Answer: 63 m
explanation: finding the area of the entire rectangle (so if the triangle wasn’t there) would be 13 x 6 which equals 78. Now we find the area of the triangle, so 6 x 5 = 30/2=15. Then you do 78-15, which equals 63. Hope this helped!

Which of the following examples would show a negative trend?
A. height and weight of students
B. test scores and height of students
C. outside temperature and heating bill
D. none of these
Answers
Explanation:
A negative trend is when one variable goes up and the other variable goes down (or vice versa).
As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.
As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.
As the name implies, negative trend graphs have negative slopes for the regression lines.

Step-by-step explanation:
As per provided information .
XQR is a straight line So, sum of all angles formed on straight line is 180° .
This Means
∠XOM + ∠MOR = ∠XQR
On putting the given value we obtain
(136 - 2a) + (3a + 39) = 180
So, the required option is (D) (136 - 2a) + (3a + 39) = 180

Geet sells television He earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Geet sells 11 televisions with extended warranties, he earns $990. How much is the fixed amount Geet earns for each television?
Answers
$30×11=$330.
Next, subtract $330 from $990.
$990–$330=$660
The fixed price for 11 televisions is $660. So, divide $660 by 11.
$660÷11=$60.
So the fixed amount that Gerry earns for each television is $60.
