Answer:
A) {(1, 2), (1, 3), (1, 1)}
Step-by-step explanation:
The x variable repeats in (1,2), (1,3), (1,1) not making it a function.
Answer:
yes

4.5
Step-by-step explanation:
Just distribute the numbers outside the parenthesis and then combine like terms. One thats done solve
Answer:
x = 13 1/2 or 27/2
Step-by-step explanation:
1st Add 2 to both sides: 2/3x-2+2=7+2
2nd Simplify: 2/3x = 9
3rd Multiply both sides by 3: 3*2/3x=9*3
4th Simplify: 2x=27
5th Divide both sides by 2: 2x÷2=27÷2
6th Simplify: x = 13 1/2 or 27/2
Answer:
-1
Step-by-step explanation:
Simplify the equation out.
y + 10 = -1x + 15
y = -1x + 5
We can use slope intercept form.
y = mx + b
We typically don't put a 1 in front of a variable, but for slope purposes, I put it.
So the slope (m value) would be -1.
