Another way to express it would be -12x+28
Answer:
There is a correlation between test score and amount of TV watched. There is probably also causation. This is because there is an increase in a
student's test score with a decrease in the amount of TV watched.
Step-by-step explanation:
I’m guessing you mean like this.
2x+4y+5x+8y.
2x and 5x are like terms because the x’s are alike. If you add 2+5, the answer is 7. So therefore 2x+5x=7x.
4y and 8y are like terms because the y’s are alike. So the answer to 4y+8y would be 12y.
If you need extra help, give me a problem and I will help you solve it.
Answer:
slope of AB = Y2 -Y1/X2 -X1
=7 - 3/-5-(-5)
=4/-5 +5 = 4/0
= undefined ( a number divided by 0 is undefined)
slope of CD =9 -9/-10-1
= 0/-11
= 0
since AB is not equal to CD
THE LINES ARE PERPENDICULAR
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?
