Answer:
the solution is (-4, -3)
Step-by-step explanation:
Multiply the first equation by 2. This produces 4x + 2y = -14.
Now combine this result with the second equation:
4x + 2y = -14
-3x - 2y = 10
------------------
x = -4
Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.
Then x = -3/2, and the solution is (-4, -3)
ANSWER:
STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:
The slope can be calculated as follows:
We use the points (4,7) and (1,1) to calculate the slope:
Now, we calculate the value of b, using the point (1,1) and the slope, like this:
Therefore, the equation would be:
Last month, she had 100.....this month, 30 new members joined and 10 cancelled....thats basically the same as saying 20 new members joined...so there are now 120 members...at 10 per subscription = 120(10) = $ 1200 <=
I think that the correct answer is D. SAS
But I’m no sure tho
Hope you get it right
