Answer:
$1.70
Step-by-step explanation:
Let the number of nickels be .
Thus, by the problem statement, the number of dimes is [/tex] 8 \cdot x = 8x. [/tex]
Therefore, there are coins in total. To find what
is, we need to solve the equation
This can be done by dividing both sides by
which gives
. Plugging these values in tells us that there are
nickels and
dimes. (Test it out!) Thus, the nickels are worth
cents and the dimes are worth
cents, so in all, you have
cents which is $1.70.
Hope this helps :)
Answer:
The graphs of the two function will not intersect.
Step-by-step explanation:
We are given a quadratic function f(x).
Also g(x) is given by a set of values as:
x g(x)
1 -1
2 0
3 1
As g(x) is a linear function hence we find out the equation of g(x) by the slope intercept form of a line: y=mx+c
let g(x)=y
when x=1 , g(x)=-1
-1=m+c----(1)
when x=2 , g(x)=0
0=2m+c------(2)
Hence, on solving (1) and (2) by method of elimination we get:
m=1 and c=-2
Hence, the equation of g(x) is:
g(x)=x-2
So clearly from the graph we could see that the graph of the two functions will never intersect.
