Answer:
A
Step-by-step explanation:
The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
<u>Answer:</u>
No, the given set of pairs does not represent a function
<u>Step-by-step explanation:</u>
For a set of values to be a function, each input must have one and only one output value

Answer:
(1 , 2)
Put the equation in the form "y=ax2+bx+c
Calculate the -b term, which is also the x coordinate of the vertex.
Plug in -b/2 into the equation for x and then solve for y.
I think the answer is a just from looking.
could you put a picture with the ruler next to all three sides please
