Which ordered pair is the solution to the system of equations?

Mathematics
1 answer:
r-ruslan [8.4K]2 years ago
8 0

Step-by-step explanation:

y = 2x - 15

4x + 3y = -5

4x + 3(2x - 15) = -5

4x + 6x - 45 = -5

10x = 40

x = 40/10

x = 4

y = 2x - 15

y = 2(4) - 15

y = 8 - 15

y = -7

Solution = (4,-7)

Option → C

What is the solution to the system of equations below?
Pachacha [2.7K]

Answer:

(-8, 2)

Step-by-step explanation:

set these equations equal to each other

1/2x + 6 = -3/4x -4

5/4 x = -10

x = -10x4/5 = -40/5 = -8

plug this x into one of the equations

y = 1/2 (-8) + 6

y = -4 + 6

y = 2

Answer:

1. 18.84 in

2. 56.52 cm

Step-by-step explanation:

The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.

1. C = πd = π(6) = 3.14(6) = 18.84 in

2. C = 2πr = 2(3.14)(9) = 56.52 cm
