Mathematics
1 answer:
andriy [413]3 years ago
4 0

Answer:

(- 1, - 5 )

Step-by-step explanation:

Given the 2 equations

y = 3x - 2 → (1)

6 + y = - x → (2)

Substitute y = 3x - 2 into (2)

6 + 3x - 2 = - x

4 + 3x = - x ( add x to both sides )

4 + 4x = 0 ( subtract 4 from both sides )

4x = - 4 ( divide both sides by 4 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = 3(- 1) - 2 = - 3 - 2 = - 5

solution is (- 1, - 5 )

Choose the ratio that you would use to convert 1.5 feet to miles. Remember
AleksandrR [38]

Answer: B, 1 mile / 5280 ft.

Step-by-step explanation: If you need to convert feet to miles the unit multiplier (ratio) that you use should have miles on top and feet on the bottom so that the feet cancel when you multiply, leaving miles as the unit. B is the only answer that has miles on top and feet on the bottom as well as the correct amounts (1 mile and 5280 ft).

1.1x + 1.2x - 5.4x = -10
IrinaK [193]
1,1x + 1,2x - 5,4x = - 10
- 3,1x = - 10
x = - 10 : (- 3,1)
x = - 10 : (- 3 1/10)
x = 10 : 31/10
x = 10 * 10/31
x = 100/31
x = 3 7/31
