Answer:
.348
Step-by-step explanation:
Let's assume
number of nickels =n
number of dimes =d
we are given
total number of coins =9
so, we get

we know that
1 nickel =$ 0.05
and
1 dimes =$0.10
so, total amount is

we are given
total amount =$2.15
so, we get

so, we get system of equations as

................Answer
An=a1+(n-1)d
A15=6+(15-1)2
A15=6+(14)2
A15=6+28
A15=34
Answer=34
So, hmmm keeping in mind that, an absolute value expression is in effect a piece-wise function, let's find its "slopes", the negarive slope on the left-side and the positive slope on the right side, and let's use the vertex point as our first point
what is the slope of a line that passes through (2, -1) and (0,7)

now, what is the slope of a line that passes through (2, -1) and (4,7)

since an absolute value expression is just a piece-wise with a +/- versions, then we can just combine those two.
Answer:The function is a direct variation function with a constant
of variation of 1.5.
