Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)

Answer:
Step-by-step explanation:
The area of a square is the square of the side length. Then the side length is the square root of the area.
- 6² = 36 . . . area of the square of leg 6
- 8² = 64 . . . area of the square of leg 8
- 36+64 = 100 . . . sum of the two leg squares = area of hypotenuse square
- √100 = 10 . . . hypotenuse length
(x,y)
P = 50x + 80y
P=(0,5)
=50(0) + 80(5)
= 0 + 400
= 400
P=(1,12)
= 50(1) + 80(12)
= 50 + 960
= 1010
P=(4,10)
= 50(4) + 80(10)
= 2000 + 800
= 2800
7+7=14
8+9=17
The closest With a double is 8+8=16
