Answer:
(- 10, 8 )
Step-by-step explanation:
A translation of 4 left means subtract 4 from the x- coordinate
A translation of 1 down means subtract 1 from the y- coordinate
(- 6, 9 ) → (- 6 - 4, 9 - 1 ) → (- 10, 8 )
Use distributive property
3(x + 2) = 2(2x + 7)
(3)(x) + (3)(2) = (2)(2x) + (2)(7)
3x + 6 = 4x + 14 |subtract 6 from both sides
3x = 4x + 8 |subtract 4x from both sides
-x = 8 |change the signs
<h3>x = -8</h3>
(1) distributive is the answer. Distributive property just means 4(x-1)=4x-4
Answer:
The mean hourly snowfall is 2.5 centimeters
Step-by-step explanation:
The mean hourly snowfall is the number of centimeters that fell during the period divided by the number of hours.
From 5 P.M. to 9 P.M., there are 4 hours
At 5 P.M., the total snowfall is 2 centimeters.
At 9 P.M., the total snowfall is 12 centimeters.
So in those four hours, the depth of snow increases 12-2 = 10 centimeters
10/4 = 2.5
The mean hourly snowfall is 2.5 centimeters
