Answer:
All you need to do is substitute.

-3 + 36/9
-3 + 4
= 1
There are 0 solutions because the lines are parallel and will never intersect.
Answer:
Hiya there!
Step-by-step explanation:
I'm pretty sure that its 80.
Answer:
3/4 shall be our slope.
Step-by-step explanation:
You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.
Your coordinates:
(-4,0) and (0,3)
You have to set up your formula:
3 is the y2 and 0 is the y1
3-0 for y so far.
Now, set up the x's
0 is our x2 more known as our second x
Then our x1 is -4
0 - (-4).
Our Formula:
3-0 / 0+4
**Notice the negatives canceled to a positive due to the rule.**
3/4 shall be our slope.
You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
Step 2: She did not simplify under the square root correctly
under the square root:
(-6)^2 =36
and -4(5)(-8) =160
therefore under the square root it needs to be square root of 36+160 which is square root of 196.
That answer is 14 when square rooted
