Answer:
368<939`01^9292^91 ibtimes
Answer:
Yes
Step-by-step explanation:
Example: Let class one have 5 male students and 4 female students and let class two have 10 male students and 8 female students, then the single class will have 15 male student and 12 female students which are in a ratio of 5:4
A function is a process or a relation that associates each element x of a set X to a single element y of another set Y.
A. The equation 
represents vertical line. This is not a function, because one element x=5 is associated to all (not one) elements of 
B. The equation 
represents parabola that goes in positive x-direction. This is not a function, because each 
is associated to two different y. For examlpe, when x=10, then 
C. The equation 
represents parabola that goes in positive y-direction. This is the function, because for each x is associated only one y.
D. The equation 
represents hyperbola. This is not a function, because for one x there are two different possible y.
Answer: correct choice is C
The rate of
Glenn in finishing a job would be equivalent to:
Rate (G) = 1
job / 20 minutes
While the
rate of Veronika is:
<span>Rate (V) = 1
job / x ---> x is the
unknown</span>
Where 1 job
for Glenn means completely cleaning his room while 1 job for Veronika means
pulling out everything. Therefore the equation to use would be:
1 / 20 – 1 /
x = 1 / 60
The rate of
Veronika is subtracted from the rate of Glenn since Veronika is slowing Glenn
down. Solving for x:
Multiply both
sides by 60 x
(1 / 20 – 1 /
x = 1 / 60) * 60 x
3 x – 60 = x
2 x = 60
x = 30
<span>Therefore it
takes 30 minutes for Veronika to pull everything out.</span>
4x+4y=-9
first change into yintercept form
y=-x-9/4
to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively
