-5 + -40 + -50 = -5 + 8 + 10
-95 = -13
135

are the answers i just did this test
I think what you are looking for is to indicate an ecuation for this. So lets do the procedure:
First you need to find the slope of this line.
<span>(5 - 6)/(5 + 1) = -1/6 </span>
<span>So, The slope of the perpendicular line is the opposite reciprocal, which is </span>
<span>+6/1.</span><span>Now we know the slope of the line but still have to find the mid point of the line. </span>
That is why we are going to <span>use the mid point equation </span>
<span>x = (-1 + 5)/2 = 2 </span>
<span>y = (6 + 5)/2 = 11/2 </span><span> </span>
<span>(y - 11/2) = 6(x - 2) </span>
<span>The last thing you do is rearrange the equation to get y = 6x - 6.5
Hope this is what you were looking for </span>
Move the figure 10 units to the right and then rotate it 90º
Hey there!
If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.
20% is the same as 1/5 of the total amount, since there are 5 20s in 100.
So, we can simply multiply 4 by 5 to get the total amount of problems.
4 x 5 = 20
This means there were 20 problems on the test.
Hope this helps!
