The answer is B. I have this question before when i was in 3rd grade once. u must be in k12
Answer:
y = 8
Step-by-step explanation:
Line1 with points (4, 1) and (0, 0):
slope = (y₂ - y₁) / (x₂ - x₁)
= (0 - 1) / (0 - 4)
= 1/4
Perpendicular line is opposite inverse so original slope 1/4 becomes -4/1 or simply -4.
Line2 with points (1, 0) and (-1, y):
slope = (y₂ - y₁) / (x₂ - x₁)
= (y - 0) / (-1 - 1)
= y / -2
y must equal to 8 for the slope to be -4 as stated above.
(C)
Step-by-step explanation:
Q.E.D means "quod erat demonstrandum" indicating that the proof is completed.
Answer:
The number of hours did Sarah practice more than Leilani is 
hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano = 
hours
The time for which Sarah practiced piano = 
hours
Let the number of hours did Sarah practice more than Leilani = T hours
<u>Now, According to question</u>
The number of hours did Sarah practice more than Leilani = hours - hours
Or, T = 
hours
Or, T = hours
So,The number of hours did Sarah practice more than Leilani = T = hours
Hence, The number of hours did Sarah practice more than Leilani is hours . Answer
Answer:
