B it is not because it fails the vertical line test
<h3>f(x) is equal to 4.5 when x = 1/2</h3>
<em><u>Solution:</u></em>
Given that,
We have to find f(x) when x = 1/2
We can solve by substituting x = 1/2 in given function
Thus f(x) is equal to 4.5 when x = 1/2
I will only be writing the reasons for each and you can respond if you need clarification for anything:
1. given
2. opposite sides of a parallelogram are congruent (and a rectangle is a parallelogram so the properties apply)
3. def rectangle
4. SAS (side angle side congruence theorem)
5. CPCTC (congruent parts of congruent triangles are congruent)
Answer:
12+x=12+4=16
3x+y=3*4+7=12+7=19
4y-10=4*7-10=28-10=18
1/2xy=1/2*4*7=28/2=14
