Answer:

Option b. degrees Fahrenheit/(mililiters)

Step-by-step explanation:

we know that

The formula to calculate the average rate of change between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have  that

the units of the y-axis are {\°F}

the units of the x-axis are {ml}

therefore

the units of the the average rate of change are

m=\frac{\°F}{ml}

Select the graph that shows the solution set for the following system.<br> x + y &lt; 2<br> x&gt;2
kompoz [17]

Answer:

Answer is in the attachment.

Step-by-step explanation:

To graph x>2 consider first x=2. x=2 is a vertical line and if you want to graph x>2 you need to shade to the right of the vertical line.

To graph x+y<2, I will solve for y first.

x+y<2

Subtract x on both sides:

  y<-x+2

Consider the equation y=-x+2.  This is an equation with y-intercept 2 and slope -1 or -1/1.  So the line you have in that picture looks good for y=-x+2. Now going back to consider y<-x+2 means we want to shade below the line because we had y<.

Now where you see both shadings will be intersection of the shadings and will actually by your answer to system of inequalities you have.  In my picture it is where you have both blue and pink.

I have a graph in the picture that shows the solution.

Also both of your lines will be solid because your question in the picture shows they both have equal signs along with those inequality signs.

Just in case my one graph was confusing, I put a second attachment with just the solution to the system.

Please Help!!<br> Write an equation of the line that passes through each pair of points.
Alex

Answer: y=-2x + 3

Step-by-step explanation:

(0,3)   and (2,-1)

3-(-1)= 4

0-2= -2  

4/-2= -2  so the slope is -2  and we already know the y intercept is 3 because that is when x is 0.

so the equation will    y= -2x + 3
