What is the result of adding these two equations? 5x−9y=1−7x+2y=−5\begin{aligned} 5x-9y &= 1 -7x+2y &= -5 \end{aligned}

5x−9y

−7x+2y



=1

=−5

-2x-7y=-4

Step-by-step explanation:

We want to add the two expressions

First we add the Left Hand Sides and do the same to the Right Hand Sides. This gives us:

(5x-9y)+(-7x+2y)= 1 +( -5)

Open the brackets

5x-9y-7x+2y=1-5

Regroup like terms

5x-7x-9y+2y=-4

-2x-7y=-4

The result of adding the two given expressions is -2x-7y=-4.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

step-by-step explanation:

where is the question is there is a formula or is there not one
