Answer:
0.2 hours
Step-by-step explanation:
The depth, d of snow (in cm) that accumulates in Harper's yard during the first h hours of a snowstorm can be calculated using the equation:
d=5h
When d=1cm, we want to determine the value of h.
1=5h
h=1/5=0.2
Therefore, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
The last line of a proof represents: The conclusion!
Answer:
(- 4, - 10 )
Step-by-step explanation:
y = 5x + 10 → (1)
y = 4x + 6 → (2)
Substitute y = 5x + 10 into (2)
5x + 10 = 4x + 6 ( subtract 4x from both sides )
x + 10 = 6 ( subtract 10 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 5(- 5) + 10 = - 20 + 10 = - 10
solution is (- 4, - 10 )
