Answer:
Yes
Step-by-step explanation:
It's just like adding fractions where you have to find the common denominator so the fractions can be subtracted.
<u>Example</u>
<u />
Formula for slope: y2-y1/x2-x1
Plug in values.
3-8/-4-(-7)= -5/3 = slope
42-1/36-12=41/24=slope

Answer:
1/12
Step-by-step explanation:
you need to make sure that they have a common denominator before doing anything.
Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)
So then, put 12 as both denominators, and subtract.
7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.
Sorry if this is confusing, i tried explaining as best i could! Hope this helped!
So we have the equation:

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

Then we subtract 9 on both sides to solve for z:

Therefore the answer is z = -0.6.
