Answer:</h3>
(5/7, 12/7) <- I think you meant to type that. Its the first one

Step-by-step explanation:</h3>
Step 1: Substitute y=x+1 in for y in 5x + 2y = 7
5x + 2(x+1) = 7
Step 2: Solve it
5x + 2x + 2 = 7
7x + 2 = 7
- 2 - 2
7x = 5
--- ---
7 7
x = 5/7
Step 3; Plug x into y=x+1
y = 5/7 + 1
y = 12/7
Answer:
Step-by-step explanation:
A = base *h /2
A = (4*15/2 )/2 = 15 in²
A = (1 and 3/7 *14/5 )/2 = (10/7 * 14/5 )/2 = 2 in²
A= (5 and 2/7 * 7/2) /2 = (37/7 * 7/2)/2 = 9.25 in²
That wil'll be. x^2×13=46
