99 9/10
3 47/50
6 1/4
12 27/50
10 1/10
Step-by-step explanation:
Answer:
55 gallons, the initial quantity of water in the tank
Step-by-step explanation:
Y is defined as the amount of water in the tank. When X (the number of minutes spent draining) is zero, no water has left the tank. So, the Y-intercept is the initial amount of water in the tank, 55 gallons.
Is d pint because the tip of a needle is just a point
11.3x + 7.2 = 86.3
11.3x + 7.2 (-7.2) = 86.3 (-7.2)
11.3x = 79.1
11.3x/11.3 = 79.1/11.3
x = 7
7 is your answer
hope this helps
y = mx + b, where m = slope, and b = y-intercept.
y = 3x + 3
y = 1/2x - 3
y = 1/2x + 3
y = 3x + 1/2
we can eliminate 2 and 4 since the y-intercept in the graph is shown as (0, 3)
This leaves us with
y = 3x + 3 and y = 1/2x+3
m = change in y / change in x
We take any two points on the line to find the slope.
I chose (2, 4), (0, 3)
change in x: 2 - 0 = 2
change in y: 4 - 3 = 1
m = 1/2
This leaves us with the only answer that has the slope of 1/2 and the y-intercept of 3.
option: 3
y = 1/2x + 3
