(2) + 2(2) - (2) - 1

  • Multiply 2 * 2 first.

(2) + (4) - (2) - 1

  • Solve from left to right.
  • (2 + 4) - 2 - 1 = 6 - 2 - 1

6 - 2 - 1

  • Solve from left to right.
  • (6 - 2) - 1 = 4 - 1

Ronch [10]

Answer:

Difference between high and low temperatures: 12°F

Average change in temperature per hour: 2°F

Step-by-step explanation:

The difference between high and low temperatures was: 7 - (-5) = 12 (°F)

Midnight is 12am, so 6pm to midnight is 6 hours.

The average change in temperature per hour is: 12 / 6 = 2 (°F)

Y = 4x – 10
aev [14]

Answer:

(3,2)

Step-by-step explanation:

y = 4x – 10

y = 2

Substitute the second equation into the first

2 = 4x-10

Add 10 to each side

2+10 = 4x-10+10

12 = 4x

Divide each side by 4

12/4 =4x/4

3 = x

The solution is

(3,2)
