Answer: y = x
<u>Step-by-step explanation:</u>
First, find the point where 5x - 2y + 3 and 4x - 3y + 1 intersect using the Elimination Method.
5x - 2y + 3 = 0 → 3(5x - 2y + 3 = 0) → 15x - 6y + 9 = 0
4x - 3y + 1 = 0 → -2(4x - 3y + 1 = 0) → <u> -8x + 6y - 2</u> =<u> 0 </u>
7x + 7 = 0
7x = -7
x = -1
5x - 2y + 3 = 0
5(-1) - 2y + 3 = 0
-5 - 2y + 3 = 0
-2y - 2 = 0
-2y = 2
y = -1
(-1, -1)
Next, find the point where x = y and x = 3y + 4 intersect using the Substitution Method.
x = y
x = 3y + 4 → y = 3y + 4
-2y = 4
y = -2
x = y
x = -2
(-2, -2)
Now, find the line that passes through (-1, -1) and (-2, -2) using the Point-Slope formula. (x₁, y₁) = (-1, -1) and m = 1
y - y₁ = m(x - x₁)
y + 1 = 1(x + 1)
y = x
If you add all of them up it would be 19, you can tell by looking at them and seeing it’s going to be over 9 so it would have to be 19
No, the answer is 2(10c + 4d)
I’m kind of in a rush so I’m not sure about these answers to be honest . But I THINK 7 is c?? And 8 might be 30? You might want to wait for someone else to answer just in case
