Nice use of brackets. We know exactly what you mean.
(10 - 7 + 2) / (-2 + 1) Notice that with an even number of - signs, you get a plus and with and odd number you get a minus.
(5) / (-1) = - 5 answer
Edit
Numerator
10 does not change.
+ - 7 Here a plus and a minus are put together. There is 1 minus sign which is an odd number of minus signs so the 7 is minus
- - 2 Here there are 2 minus signs. They become plus because 2 is even, and an even number of minuses become a plus so you have +2
10 - 7 + 2 = 5
Denominator
-2 does not change. It remains minus 2.
- - 1 There are 2 minus signs so this becomes plus 1.
- 2 + 1 = - 1
Numerator over denominator = 5/-1 = - 5. I'll probably run out of editing time. If you still don't understand, try and pinpoint the problem and we'll keep trying until you do see it. This question is worth it.
Answer:
8
Step-by-step explanation:
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
Step-by-step explanation:
Given equation of line is:
We have to convert the given line in slope-intercept form to find the slope of the line
So,
Dividing both sides by 4
Let m1 be the slope of given line
Then
Let m2 be the slope of line perpendicular to given line
As we know that produt of slopes of two perpendicular lines is -1
The slope intercept form of line is given by:
Putting the value of slope
to find the value of b, putting (3,-3) in equation
Putting the value of b in the equation
Hence,
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

If you would like to know how many square feet of the wall will be blue, you can calculate this using the following steps:
8 2/5 feet high * 16 2/3 feet long = 8 2/5 * 16 2/3 = 42/5 * 50/3 = 140 square feet
1/2 * 140 = 140/2 = 70 square feet
<span>The correct result would be 70 square feet.</span>
