Answer:

3x+3y−z−7

Step-by-step explanation:

"Let's simplify step-by-step.

4x+2y−z−(x−y+7)

Distribute the Negative Sign:

=4x+2y−z+−1(x−y+7)

=4x+2y+−z+−1x+−1(−y)+(−1)(7)

=4x+2y+−z+−x+y+−7

Combine Like Terms:

=4x+2y+−z+−x+y+−7

=(4x+−x)+(2y+y)+(−z)+(−7)"(Mathpapa)

HELP Luna observed that in the last 12 issues of Rise Over Run Weekly, 384 of the 960 pages contained an advertisement.
Veseljchak [2.6K]
Well, 12 issues end up as 960 pages total

so... if in 960 pages, 384 are ads, what about 80 pages?

well \bf \begin{array}{ccllll}
pages&ads\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
960&384\\
80&x
\end{array}\implies \cfrac{960}{80}=\cfrac{384}{x}

solve for "x"

A bag holds 1 blue block and 3 yellow blocks. How many green blocks should be added to the bag to make the probability of random
Drupady [299]
n - the number of green blocks which is equal to the number of favourable events
1+3+n=4n - the number of all blocks, which is equal to the number of all possible outcomes

P(A)=\dfrac{n}{4+n}=\dfrac{1}{2}\\
1\cdot( 4+n)=2\cdot n\\
4+n=2n\\
2n-n=4\\
n=4

1. for what constant k must f(k) always equal the constant term of f(x) for any polynomial f(x) 2. If we multiply a polynomial b
DIA [1.3K]

Answer:

1. k=0

2. yes, result is still a polynomial.

3. yes, f and g must have the same degree to have deg(f+g) < deg(f) or deg(g)

Step-by-step explanation:

1. for what constant k must f(k) always equal the constant term of f(x) for any polynomial f(x)

for k=0 any polynomial f(x) will reduce f(k) to the constant term.

2. If we multiply a polynomial by a constant, is the result a polynomial?

Yes, If we multiply a polynomial by a constant, the result is always a polynomial.

3. if deg(f+g) is less than both deg f and deg g, then must f and g have the same degree?

Yes.  

If

deg(f+g) < deg(f) and

deg(f+g) < deg(g)

then it means that the two leading terms cancel out, which can happen only if f and g have the same degree.

A University has 30,600 students think school counselor estimates that 2% of the students break three on my languages in a rando
xxTIMURxx [149]

Answer:

Counselor's estimate isn't correct.

Step-by-step explanation:

Total number of students in university = 30,600

2% break 3 of the languages

Therefore, 2/100 × 30600 = 612 students break 3 of the languages in the University according to the counselor.

In a random sample of 240 students, 20 break 3 of the languages.

% = 20/240 × 100 = 8.33%

SinceTotal number of students = 30,600

Therefore, 30,600/240 = 127.5

Which means 127.5 × 20 = 2550.

Which means 2550 students break 3 of the languages as against the 612 students stated by the counselor.
