Answer:
y-intercept = 3
The y-intercept represents the initial fee before any miles are traveled.
Step-by-step explanation:
By definition, the <u>y-intercept</u> is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The coordinates of the y-intercept is (0, <em>b </em>).
Looking at your graph, it shows that the line crosses the y-axis at (0, 3). Therefore, the y-intercept = 3.
The y-intercept represents the initial fee before any miles are traveled. This means that the taxi ride already has a set amount of $3, regardless of the number of miles traveled. This is added to the total cost of the taxi fare, which is represented by y.
Assume we need to add x litters.
So we are going to mix x liters (25% saline) and and 3 liters (10% saline).
In total we are going to have a x+3 litters (of 15% saline).
a. of the x liters, 25/100x=0.25x is saline. so we have 0.25x liters saline.
b. of the 3 liters, (10/100)*3=0.1*3=0.3 liters is saline.
c. of the x+3 liters, (15/100)(x+3)=0.15(x+3)=0.15x + 0.45 liters is saline
equalize:
0.25x + 0.3 = 0.15x + 0.45
0.25x - 0.15x = 0.45 - 0.3
0.1 x =0.15
x=0.15/0.1= 1.5 (liters)
Answer: 1.5 liters
