148/7 or

Step-by-step explanation:

29/4 + 29/7 + 39/4 = 29×7/4×7 + 29×4/7×4 + 39×7/4×7 = 203/28 + 126/28 + 273/28 = 329/28 + 273/28 =

592/28

÷4 ÷4

= 148/7 (GCF)

________________________________

First cross multiply to the LCD(least common denominator or the multiple that the numbers have in common so they have the same denominator, and can be added).

Then add the numerators together and divide by the common denominator.

To simplify the fractions, find the greatest common factor.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
