Answer:
Students on Honor Roll had no advantage to get the Science class requested. It was a fair class assignment. In fact No Honor Roll students had advantage over honor Roll Students in obtaining Science Class as requested.
Step-by-step explanation:
Here let us streamline the information we are given one by one
1.) Honor Roll
Get Requested Science Class : 64
Did Not get Requested Science Class : 80
Total : 144
Percentage of Honor Roll Students getting Science class as requested =

= 44.44%
2.) No Honor Roll
Get Requested Science Class : 315
Did Not get Requested Science Class : 41
Total : 356
Percentage of Non Honor Roll Students getting Science class as requested 
= 88.8%
By observing the above result , we can assume that Honor Roll students did not have any advantage over non Honor Roll students in getting Science Class as they requested.
For this case what you can do is factorize the <span>polynomial equation</span>, which would be left like follows
x ^ 3 + x ^ 2 + 9x + 9 = 0
(x + 1) (x ^ 2 + 9) = 0
Resolving, we have that the missing root is
x = -1
Answer
x=-1
Answer:

Step-by-step explanation:
Suppose h is the inverse of f then
f(x) = y ⇔ h(y) = x
f(x) = y ⇔ 4x = y ⇔ x = y/4
and since x = h(y) then h(y) = y/4
then we can write :

Step-by-step explanation:
<u>ANSWER:
</u>
(-5, 0.5) is the solution of given equation x – 4y = –7, 0.2x + 2y = 0.
<u>SOLUTION:
</u>
Given, two equations are x – 4y = -7 → (1)
And 0.2x + 2y = 0 → (2)
We have to find whether (-5, 0.5) is a solution of given system or not.
For that, we have to solve the given two equations.
Before solving let us multiply equation (2) with 2 in order to get y terms cancelled. Such that, our process becomes easy.
Now equation (2) becomes
0.4x + 4y = 0 → ( 3 )
Now, add equation (1) and equation (3), we get
1.4x + 0 = -7

Now, substitute x value in (2)
0.2(-5) + 2y = 0
-1 + 2y = 0
2y = 1
y = 0.5
So, the solution for given equations is (-5, 0.5).
Hence (-5, 0.5) is the solution of given equations.
