Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
Answer:
25 questions
Step-by-step explanation:
At a math competition 2 students can answer 40 questions in 1 hour.
Therefore, 1 student can answer in 1 hour = 
= 20 questions
5 students can answer in 1 hour = 20 × 5 = 100 questions
60 minutes = 1 hour
15 minutes = 
= 0.25 hours
5 students can answer in 0.25 hours = 100 × 0.25
= 25 questions
5 students could answer 25 questions in 15 minutes.
Answer:
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
Step-by-step explanation:
Let the width be x.
width = x
length = x + 8
The area is 20 ft²
x(x + 8) = 20
x² + 8x = 20
x² + 8x - 20 = 0
(x + 10) (x - 2) = 0
x = -10 (rejected) or x = 2
Width = x = 2 ft
Length = x + 8 = 2 + 8 = 10 ft
Answer: The width is 2 ft and the length is 10ft.
