Hello!
We can find out our answer by plugging in the point (1,1) to see which equation works.
y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1
As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.
I hope this helps!
Answer:
n = 109/ 5 if the expression is 5n - 5.3 = 56
The ore the answer is B. Why?
Because (-4m+1) + (7m-9) = 3m - 8
You add -4m and 7m and get 3m and the only answer that has a POSITIVE 3m is B.
Anyways, you still have to check it. 1+(-9) is -8. So A+B = 3m - 8
Combine like terms:
-r-10r
We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.
We can't add 3r^2+10r. That's also impossible.
However, we have the same variable, r. So we can add -r-10r. And the answer is:
-11r
Hope this helps! :)
