<h3>
Answer: Choice B</h3>
Reason:
Choices A, C and D have repeated x values. It allows us to rule them out.
Table A has x = 6 repeating. Table C has x = 3 and x = -3 repeated. Table D has x = 4 and x = 5 show up twice each.
Whenever we have repeated x values, it indicates we do <u>not</u> have a function. A function is only possible when each x value goes to exactly one y value only.
Table A has the input x = 6 lead to y = 2 and y = -2 at the same time. Table C and table D are a similar story. So this is another way to rule out choices A, C and D.
Luckily table B has no repeated x values. Each x input leads to exactly one and only one y output. Therefore, <u>table B</u> is a function.
Side Note: the y values can repeat, but the function won't be one-to-one.
X>1 is the answer
10x + 16 > 6x +20
4x +16 > 20
4x > 4
x > 1
Answer:
3 follows 4 from 5 backwards
Answer:
The value of x is 12.
Step-by-step explanation:
To make the denominators the same we can: Multiply the top and bottom of each fraction by the denominator of the other.
Cross multiply with each other.
