So for this question (for finding x and y) you will want to use elimination. To do this you will need to bring the x and y to the same side (I put them on the left):
-3/2x+y=6
x+y=0
Now subtract the y on the bottom from the top to isolate x:
3/2x=6
Now the easiest way to bring over the 3/2 to isolate the x fully is to convert it to decimal (1.5) and divide it by 6 (because when multiplication on one side of problem the only way to bring it over is to divide):
x=6/1.5
which simplifies to:
x=4
Hope this helps!
Answer:
f(10x-8)=-20x+22
f(g(x))
possibly
g(-2x+6)=-20x+52
g(f(x))
If needing a different answer math-way can possibly help you as it helped me.
Answer:
$ 903.84
Step-by-step explanation: First find the perimeter, width + length + width + length. Then multiply it by 3 as the border is 3 bricks tall, divide it by 1.5 then multiply by 2.88 to get the price of the border. Add $420 to get the final price.
Answer:
I believe the answer would be 8 because if you divide 32 by 4 you get eight and that would be 1/4 of 32
