y = 4x – 10 y = 2 what is the solution to the system of equations? a.(3, 2) b.(2, 3) c.(–2, 2) d.(2, –2)
Anuta_ua [19.1K]
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:

  • 36
  • 64
  • 100
  • 10

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

Use the objective function P = 50x + 80y to calculate the profit at each point. (0, 5) P = (1, 12) P = (4, 10) P =
tatuchka [14]
(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
