Answer:
The initial value of the function is 5
Step-by-step explanation:
we know that
The initial value of the function, is the value of the function when the value of x is equal to zero (the y-intercept)
In this problem
Observing the graph
The y-intercept is the point (05)
therefore
The value of the function for x equal to zero is 5
You can write the proportion as 2 equal fractions or as two equal ratios.
or 12 pens:$10 = x pens:$15You can buy x pens for 15 dollars. One way to find x is by cross multiplying the fractions.
10x=12×15
10x=180
----- -----
10 10
x=18
You can buy 18 pens for $15.
