Answer:
None of the above.
Step-by-step explanation:
All of these are functions. For each input of x, there is only one output of y. Therefore, they are all functions.
Answer:
16 yards
Step-by-step explanation:
- Square: all sides are equal
- Square: 4 sides total
- Perimeter of square: 2 + 2 + 2 + 2
- 2 + 2 + 2 + 2 = 8 yards
- Perimeter of second box: 2 + 2 + 2 + 2 = 8 yards
- Perimeters in total: 8 + 8 = 16 yards
I hope this helps!
Answer:
d
Step-by-step explanation:
Radius = 4
area:
4x4x3.14x12=602.88
Step-by-step explanation:
x = number of true/false questions
y = number of multiple choice questions
x + y = 40
2x + 3y = 144
from the first equation we get
x = -y + 40
this identity we can then use in the second equation
2(-y + 40) + 3y = 144
-2y + 80 + 3y = 144
y + 80 = 144
y = 64
and
x + 64 = 40
x = -24
that does not make any sense.
something is wrong with the problem description.
just think about it :
40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.
but the description says 144 points.
for 144 points we need at least 48 (144/3) questions.
that does not fit.
the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.
I think the variation is x. because for have the y-intercept if yo move x
