The answer is 19. I hope this helped! If you're taking a test, good luck!
Answer:
y = -2
Step-by-step explanation:
Put x as -19 and solve for y.
2(-19) - 5y = -28
Multiply.
-38 - 5y = -28
Add 38 on both sides of the equation.
-5y = -28 + 38
-5y = 10
Divide both sides by -5.
y = 10/-5
y = -2
Answer:
12.5 hours.
Step-by-step explanation:
First man walks in one hour = 6 miles
Second man walks in one hour = 10 miles
Since they are walking in opposite direction so distance between them after 1 hour = 6 + 10 = 16 miles
Since after one hour they are 16 miles apart from each other
Therefore, they will be 200 miles apart from their starting point
= 200 ÷ 16 = 12.5 hours.
After 12.5 hours they would be 200 miles apart.
Answer:
No
Step-by-step explanation:
You can tell if something is a function by checking to see if a vertical line will intersect at one spot more than once. If it does, it is not a function.
The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x
<h3>How to determine the equation?</h3>
The attached table of values represents the missing piece in the question.
Start by calculating the rate of change using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (14.77 - 10.55)/(7- 5)
Evaluate
m = 2.11
The equation is then calculated using:
y = m(x - x1) + y1
This gives
y = 2.11(x - 5) + 10.55
Evaluate
y = 2.11x - 10.55 + 10.55
y = 2.11x
Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x
