Answer:

7-(-12)= 19

Step-by-step explanation:

7-(-12)changes to 7+(12) with the rule of <em>Same Change Change </em>or <em>SCC.</em>

<em>And 7+12 is 19.</em>

Answer:

7 - (-12) = 7 + 12 = 19

Step-by-step explanation:

- (-12) is a double negative which means that the minus signs cancel out causing it to to be a positive 12

5 is not the answer because 7 + 12 is 19

Use the trend line to predict the wind chill at these wind speeds<br> (9 and 10)
vfiekz [6]
First, you need to find the trend line that you are going to use before you can answer question 9 and 10. 

To do that select 2 points from your list and find the y = mx + b equation. 

After you have your equation, all you need to do is plug in the values that you are given for x. Evaluate the expression and you will have your answer.

Which system of equations is graphed on this coordinate plane​
Allisa [31]

Answer:

y=(3x/2)+3 and y=(-1x/2)-1

Step-by-step explanation:

So what I did was use rise/run to find the slope of the equation. Let's focus on the line going from the bottom left to the top right corner. For this line, I would start on (-2,0) which is one of the points plotted on your number line and count how much it is away from (0,3). You should get 3 units. After this, count how much it is to the right which is 2 units. Now, use rise/run to find the slope. 3/2, therefore the slope of the line is 3x/2.  Now all we need is the y-int. For the Y int, all we have to do is see where the line touches the Y-axis which in this case is at (0,3). So your y-int would be 3. Now we can use this information to craft an equation in the form y=mx+b, m being the slope and b  being the y int. We should get y=(3x/2)+3. Now repeat this with the other line to find the equation, but be careful!!! It has a negative slope.
