Answer:
1. Not a Function
2. Function
3. Not a function
Step-by-step explanation:
If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.
It’s the first one because the parabola is open
x - first number
x + 18 - second number
x + (x + 18) = 36
x + x + 18 = 36
2x + 18 = 36 | - 18
2x = 18 | : 2
x = 9
First number: x = 9
Second number: x + 18 = 9 + 18 = 27
Those numbers are 9 and 27.
Answer:
n = m + 14
Step-by-step explanation:
To "solve for n," we take steps to isolate n on the left side of this equation and everything else on the right side.
Start by adding 14 to both sides. The result is n = m + 14.
This is the desired result: n = m + 14.
Answer:
6
Step-by-step explanation:
1/2 + 1/2 = 1
1/2 + 1/2 = 1
1/2 + 1/2 = 1
There are 6 halves that equal 3.
Another way to do this is:
1/2x = 3
3 / 1/2 = 6
x = 6
