It makes it so that you can solve for the sides and such of a triangle using theorems specific to right triangles.
Answer:
x=-1, y=-5. (-1, -5).
Step-by-step explanation:
y=-x-6
y=x-4
----------
-x-6=x-4
-x-x-6=-4
-2x-6=-4
-2x=-4+6
-2x=2
x=2/-2
x=-1
y=-1-4
y=-5
<span>use the simple interest formula</span>
5 - 8x < 2x + 3
5 - 8x < 2x + 3
<u>-3 - 3 </u> Step 1.
2 - 8x < 2x
<u> +8x +8x </u> Step 2. Missing step
2 < 10x
<u>÷10 ÷10</u> Step 3.
<u>2/10 < x</u>
<u>1/5 < x
The missing step is add 8x to both sides of the inequality.</u>
