Answer:
[12, 15]
Step-by-step explanation:
{6x + 5y = 147
{8x + 4y = 156
-¾[8x + 4y = 156]
{6x + 5y = 147
{-6x - 3y = -117 ← New Equation
________________
2y = 30
___ ___
2 2
y = 15 [Plug this back into both equations to get the x-coordinate of 12]; 12 = x
So, using the Elimination Method, what I did here was took the bottom equation and multiplied it by -¾, turning 8x to -6x, canceling out all <em>x-terms</em><em>.</em><em> </em>It does not matter which variable you choose to eliminate, as long as you know what you are doing.

The answer is 5:9 or 5 to 9.
Please mark me as the brainiest answer if there's a chance :)

I would go with c. It looks like point b is where the right triangle is
-5(x+7)<-10
ok so we need to distribute the -5 into the x and 7.
-5x+-35<-10
then, we combine like terms.
-5x+-35<-10
+35 +35
-5x<25
Then, we get the variable to be by itself.
-5x<25
divide by -5
x<-5
Hope this helps! If you still don't get it, ask me.
Answer: False!
This equation is in slope - intercept form, where y = mx + b. B is the y - intercept and m is the slope. They got the location of the y - intercept right, but they forgot to add the negative. It's actually -8.
Hope this helps!
