Answer: someone plz help
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
-3 = -2x +1
+3 +2x = +2x +3
2x=4
divide them both by 2
x=2
the slope would be -0.4 sorry I couldn't get the faction
Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?
If so, then the solutions are x = -5 and x = 13 .
If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.
Answer: 2 Fahrenheit per hour
Step-by-step explanation:
From the question, we are given the information that the outside temperature decreases by 7 fahrenheit in 3 1/2 hours.
The temperature change as a unit rate will then be calculated as:
= 7 ÷ 3 1/2
= 7 ÷ 7/2
= 7 × 2/7
= 2 Fahrenheit per hour
It Decrease at 2 Fahrenheit per hour
