Solve the following systems of equations
Varvara68 [4.7K]

Answer:

(-1;1) and (0;4)

Step-by-step explanation:

First of all, even if the system is of 4th degree, by looking at the shape of the equations I am expecting up to 2 solutions.

The easiest way to solve it, since both equation are in the form y= something, is to equate both RHSs.

3x^2+6x+4=-3x^2+4\\6x^2+6x=0 \rightarrow 6x(x+1)=0

which tells us that either x=0 or x=-1

Now we can replace these value of x in one of the two to finish our work: x=0\rightarrow y= 4

x=-1 \rightarrow y= -3+4=1

Can you divide the number 8,101,265,822,784 by 8 without using either long or short division?
LuckyWell [14K]
Yes. If we wanted to divide  104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:

104=80+24

then \frac{104}{8}= \frac{80+24}{8}= \frac{80}{8}+ \frac{24}{8}=10+3=13

We use the same procedure to divide the given number by 8:



First  We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.

That is 

 <span>8,101,265,822,784 = 8,000,000,000,000+100,000,000,000+1,000,000,000
</span>
+265,822,784

now decompose 265,822,784:

265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784

now decompose 22,784

22,784=16,000+6,784

decompose 6,784

6,784=6,400+384= 6,400+320+64


Thus:

 8,101,265,822,784 : 8 =(8,000,000,000,000+100,000,000,000+1,000,000,000+240,000,000
+24,000,000+1,000,000+800,000+16,000+6,400+320+64):8

=1,000,000,000,000+12,500,000,000+125,000,000+30,000,000+
3,000,000+125,000+100,000+2,000+800+40+8

=(1,000,000,000,000+12,500,000,000)+(125,000,000+30,000,000)
   + 3,227,848

=1,012,500,000,000+155,000,000+3,227,848

=1,012,655,000,000+3,227,848

=1,012,658,227,848

On what interval(s) is the graph decreasing? - use interval notation
Anna [14]
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).  

The function is increasing on (-3,1).

No local or absolute minimum.

(1,4) is an absolute max.

The value of (a+b)² - (a-b)² is​
ANEK [815]

Answer:

4ab

Step-by-step explanation:

(a+b)^2-(a-b)^2

=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)

=a^2 + 2ab + b^2 - a^2 + 2ab - b^2

=2ab + 2ab

=4ab
