Mike is 29.
5+2x+x=41
5+3x=41
3x=36
x=12
5+2x=Mike’s Age
5+2(12)= Mike’s Age
29= Mike’s Age
Answer:
It is a function
Step-by-step explanation:
A function is of the form:
![\left[\begin{array}{c}x_1&x_2&x_3\\-&-&-\\x_n\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx_1%26x_2%26x_3%5C%5C-%26-%26-%5C%5Cx_n%5Cend%7Barray%7D%5Cright%5D)
![\left[\begin{array}{c}y_1&y_2&y_3\\-&-&-\\y_n\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dy_1%26y_2%26y_3%5C%5C-%26-%26-%5C%5Cy_n%5Cend%7Barray%7D%5Cright%5D)
Where each of the x values must be distinct.
The x values are referred to as domain while the y values are called range.
Having said that, the given data can be represented as follows:
![\left[\begin{array}{c}-3&1&6\\7&12\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D-3%261%266%5C%5C7%2612%5Cend%7Barray%7D%5Cright%5D)
----------- ![\left[\begin{array}{c}7&-8&-6\\-8&2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%26-8%26-6%5C%5C-8%262%5Cend%7Barray%7D%5Cright%5D)
<em>From the representation above, none of the x values are repeated.</em>
<em>Hence, it is a function</em>
<span>N + D = 55 coins (1) (N stands for nickels,
5N + 10D = 390 cents (2) D stands for dimes)
Simplify (2) by canceling the factor 5 in both sides:
N + 2D = 78 (3)
Subtract eq(1) from eq(3). You will get
D = 78 - 55 = 23.
Answer. 23 dimes and 55-23 = 32 nickels.
Check. 23*10 + 32*5 = 390 cents</span>
Answer:
Negative slope
Step-by-step explanation:
This is a negative slope because when you plot the numbers on the graph it makes a negative slope.
