The set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
<h3>When does a relation represents a function?</h3>
A set, or a relation, represents a function when <u>each value of x is mapped to only one value of y</u>.
In this problem, we have that option A represents a function, as:
- In option B, x = 2 and x = -2 are mapped to two values.
- In option C, x = 4 is mapped to four values.
- In option D, both x = 1 and x = 2 are mapped to two values.
Hence the set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.

Answer:
y=-7
Step-by-step explanation:
first, you want variables on one side, numbers on the other side of the equation.
4y+4=2y-10
*plus ten on both side to get rid of -10*
4y+14=2y
*minus 4y on each side to get rid of 4y*
14=-2y
*divide by -2 on each side to get the value of just one y itself*
y=-7
Answer:
Consider this: factors that are the same that are in the numerator and denominator of a fraction cancel out.
e.g. 20/30 = [2(10)]/[3(10)] = 2/3 This is because the 10 present in the numerator exactly equals the 10 present in the denominator.
We can use the above principle for these types of problems!
If the projectile is fired at 422 mi/hr, and we want to convert this speed into m/s, we just need to go through the following process:
422 mi/hr * 1610m/1mi * 1hr/60min * 1min/60s = 189 m/s
