Let n = number of nickels, and p = number of pennies.
The number of coins is 25, so we get this equation.
n + p = 25
The value of the coins is 0.05 per nickel, and 0.01 per penny.
0.05n + 0.01p = 0.73
Now you have a system of equations.
n + p = 25
0.05n + 0.01p = 0.73
Solve the first equation for n:
n = 25 - p
Now substitute into the second equation.
0.05(25 - p) + 0.01p = 0.73
1.25 - 0.05p + 0.01p = 0.73
-0.04p = -0.52
p = 13
There were 13 pennies.
Now we substitute 13 for p in n + p = 25 to find out the number of nickels.
n + 13 = 25
n = 12
There are 13 pennies and 12 nickels.
Check: 13 pennies and 12 nickels does total 25 coins.
13 * 0.01 + 12 * 0.05 = 0.13 + 0.60 = 0.73
The value is $0.73.
Our answer is correct.
I believe the answer to your question id they first one and its f(x)=3x-3
The domain is the values of x from the x-axis that 'cover' the given function.
Look at the end points of the graph and the corresponding values of x on the x-axis. These go from - 5 to 4
Thus the domain is x ∈ [- 5, 4 ] ← domain
The square bracket indicates that the values of - 5 and 4 are included in the domain
Whereas (- 5, 4 ) indicates that - 5 and 4 are not included but all values in between are
The range is the values of y from the y-axis that cover the given function
Look at the minimum value and maximum value of the function along the y-axis
The minimum is 0 and the maximum is 5
range is y ∈ [0, 5 ]
To determine the value of y when x = -3
Locate x = - 3 on the x-axis, move up vertically until the line representing the function is met, and read off the corresponding y value to the right on the y-axis
The value of f(x) when x = - 3 is 2
