Answer: y=-3x+29
Step-by-step explanation:
First put in y-intercept form to find the slope
Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3
Use the point and the new slope to write the new equation in point slope format
Answer:
She made an error when using the zero pair.
Step-by-step explanation:
In step 2, Carianne added 4 to the right side and subtracted 4 on the left side, which is completely changing the equation. By definition, your zero pair must have a difference of zero. She need to add 4 to both sides to continue; when manipulating algebra you need to do the same thing to both sides of an equation, otherwise you're just changing the equation.
Answer: I believe your answer is 17.
Step-by-step explanation: 3a+5+8
Since there is only one a you can turn the a into a 1. So it’s now 3+1+5+8=17 it’s either that or it’s 3x1+5+8= 16
So your answer is either 16 or 17 I believe. Hope I helped!
I think for the first one you do 8 times 9 and then 5 times 5 and add them together, I’m not sure though because I learned that a few years ago
