Answer:
A
Step-by-step explanation:
A function is not allowed to have two Y values for the same X value. Any table with the same X value appearing more than once is <em>not a function</em>. Only table A qualifies as a function.
Answer:
the answer should be D
Step-by-step explanation:
Answer:
If the two numbers are x and y, then:
x + y = 8
18 - 2x = 4y - 2.
When we subtract y from both sides in our first equation we get:
x = 8 - y, so:
18 - 2(8 - y) = 4y - 2
18 - 16 + 2y = 4y - 2
2 + 2y = 4y - 2
2y = 4
y = 2
Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.
