The ordered pair is (-2, -3)
Step-by-step explanation:
- Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.
(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1
(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1
(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1
(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1
So the ordered pair is (-2, -3)
You dived 14.28/4.2 by taking the decimal out and when you get the answer put it back
Answer:
1.2°F
Step-by-step explanation:
Given that:
The drop in temperature in degree Fahrenheit over a period of 14 days = 16.8
The average daily rate of change in degwrr Fahrenheit ;
Total drop in temperature / number of days
= 16.8°F / 14
= 1.2°F
Hence, the average daily drop in temperature is 1.2°F
