Answer:
I can't tell u the answer but brackets always comes first.
-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56
so x is 16.3 thats how you get this expession
-24x +56
It should be true
I'm doing mines right now so
Answer:
The north campus had 
while the south campus had 
.
Step-by-step explanation:
The question stated that there are 
students in the merged campus. That's the sum of the number of students in the north and the south campus before the merger.
Let 
denote the number of students in the north campus before the merger. The other 
students would all belong to the south campus before the merger.
Before the merger, 
of the students of the north campus are of music majors. In terms of , that's 
students.
On the other hand, 
of the students of the south campus are of music majors. That corresponds to 
students.
With a similar logic, the number of music students in the merged east campus will be 
.
The question implies that the sum of students in the two campuses should be equal to the number of music students in the east campus. That is:
.
Solve for :
.
In other words, there are students in the north campus and 
students in the south campus before the merger.
Answer:
y = -4(x+2)^2 +2
Step-by-step explanation:
y = -4x^2 -16x-14
Factor out a negative -4 out of the first two terms
y = -4(x^2 +4x) -14
We will complete the square
(b/2)^2 is what we need to add
(4/2)^2 =2^2 =4
Remember the -4 on the outside so when we add 4 on the inside we are really adding -4*4 = -16 so we need to do the opposite on the outside -(-16) and add 16
y = -4(x^2 +4x+4) -14 +16
Simplify inside the parenthesis
y = -4(x+2)^2 +2
