Step 1) Combine like terms/variables.
7y and -2y are similar, combine them.
7+(-2y)=5y
3x has no similar variables, so it stays the same
3 and 6 are similar, without variables, combine them.
3+6=9
The final answer is 5y+3x+9
Your numbers are all over the place, I will assume that you are saying that the slope is 13.
Looking at the formula for calculating slope/gradient, it is Rise/Run.
Rise/Run = y2 - y1 divided by x2 - x1. The reason for this is because if you minus one y value from the other y value you get the difference in values which is the rise, and if you minus one x value from the other x value you get the difference in value which is the run.
So by using this formula, you get:
(7 - 6) / (v - 9) = 13
Therefore 1/(v - 9) = 13
If you multiply both sides by (v-9), you get 1= 13v - 117
you rearrange it to 13v = 118
If you divide by 13, you get your answer = 9.0769
You can check your answer by putting this value back into the gradient formula.
(7-6)/(9.0769-9)
=13.004
Answer:
27
Explanation:
(a+b)^3
= (2+1)^3
= 3^3
= 27
I hope this helped! Please comment if you have any questions :)
The answer would be D I and II only
My work:
The only answer that has both statement I and statement II as true is D<span>, but if you have time and want to be absolutely thorough, you can also check to see if statement III is true </span>
