For me the easiest way would be to change to slope formula, y=Mx+b where m is the slope and b is the y-intercept. So first you want to get y by itself so I subtract 10 and subtract 2x to get 5y=-2x+10. Then divide by 5 to get y=-2/5x + 10. Start the graph by plotting the point (0,10) and then from there, use the slope of negative two fifths. Remember rise over run!

inn [45]

Answer:

The constant in the expression is 12

Step-by-step explanation:

The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can  be written as :

f(m)=0.05m +12

Example if m is 1 or 2

f(1) = 0.05(1) +12 = 12.05

f(2= = 0.05*2 +12 =0.1 +12 = 12.1

The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.

Ivan

Answer:

8\frac{3}{4} cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4}

= 8\frac{3}{4} cups.

A class of 32 students contains 15 boys.
LiRa [457]

Answer:

11 boys walk to school each day

Step-by-step explanation:

<em>*The following will be assumed: the only genders of students in the class are male or female; the only options for getting to school are walking or not walking</em>

If there are 32 students in the class total, and there are 15 boys,

32 - 15 = 17

there are 17 girls.

If 8 of these girls do not walk to school,

17 - 8 = 9

9 girls walk to school

So, if 20 total students walk to school, and 9 of those are girls

20 - 9 = 11

11 boys walk to school each day.
