The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
Answer:
for 10 people she makes 35$
for 20 people she makes 55$
for 30 people she makes 75$
and for 40 people she makes 95$
Step-by-step explanation:
just plug the number of people (10, 20, 30, 40) into the x in the equation.
Answer: -x^2 + 15x
Step-by-step explanation:
Isn’t it supposed to be a minus sign? For it can be like w-2, w-2 ?
Answer:
a.) May or may not a polynomial function ( depends on c)
b.) Not a polynomial function.
c.) Not a polynomial function.
d.) It is a polynomial function.
Step-by-step explanation:
A polynomial function is of the form - 
where n is positive integer and n
0
a.)
P(x) = 2x³ + 32 - 4x + 4c
It may or may not a polynomial function because we did not know about the constant c.
b.)
H(x) = 4
- 3x⁴
It is not a polynomial function because
is not integer.
c.)
G(x) = 2
+ 5
It is not a polynomial function because -5 is not a positive integer.
d.)
F(x) = 2x³ - 5x + 33x²
It is a polynomial function.
