A) y= (-1/2)x+50
(y=(-1/2)4 +50 = -2+50= 48)
Y=( -1/2 )8-50=-4+50 =46
B) -1/2X+50>=40
-1/2X>= -10
X<=20
To start the meeting with 40 students it should be 20 minutes or less before the meeting
Draw the line with the zero in the middle
Draw a closed circle at +20 and from that point draw a line to the left
Answer:
None of the above.
Step-by-step explanation:
Let us check each of the answer choices one bye one.
Choice A: 
solving for y we get:

which is not equal to our function h(x).
Choice B:
.
This gives 
which is not equal to our function h(x).
Choice C:
and
.
The first expression does not contain y, thus it is not equivalent to h(x). The second equation already gives the value of y , and we see that it is not equal to h(x).
Therefore we conclude that none of the choices given are correct.
No it's not because the length of a rectangle is not always but some times do and you can search on internet or ask your teacher too that might be helped I think may be.
5 × 3/4 = 3.75
4 1/4 × 3/4 convert it into an inproper fraction.
17/4 × 3/4 = 3.1875
1/2 × 3/4 = 0.375
3/3 × 3/4 = 0.75
So you're answer is: 1/2×3/4, 3/3×3/4, 17/4×3/4, 5×3/4
