Answer:
The number of adults, a, is 300, and the number of kids, k, is 200.
Step-by-step explanation:
k + a = 500 (1)
3k + 10a = 3,600 (2)
Multiply both sides of equation (1) by -3.
(k + a) • -3 = 500 • -3
-3k − 3a = -1,500
Now, add this equation to equation (2).
3k + 10a = 3,600
+ -3k − 3a = -1,500
7a = 2,100
a = 300
Substitute the value of a into equation (1).
k + a = 500
k + 300 = 500
k = 500 – 300
k = 200
In the system of equations, a represents the number of adults and k represents the number of kids who visited the carnival. The number of adults, a, is 300, and the number of kids, k, is 200.
Answer:
y = mx+b
Step-by-step explanation:
The slope intercept formula for a line is
y = mx+b where m is the slope and b is the y intercept
The give problem is NOT a function.
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same input and different outputs. Thus, a function can only take on one output for each input.
In the given problem, q has two output values: y and z. Therefore, the given relation is not a function.
