Help! I have solving systems of equations using substitution, and sometimes I have equations like this:

timurjin [86]

For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.

What is the result when 3x^4+2x^3-5x^2-6x-2 is divided by x+1

SCORPION-xisa [38]

Answer:

The answer to your question is: 3x³ - x² - 4x - 2

Step-by-step explanation:

Data

3x⁴ + 2x³ - 5x² - 6x - 2

x + 1

Process

Synthetic division

3 2 -5 - 6 -2 -1

-3 1 4 2

3 -1 -4 -2 0

Result 3x³ - x² - 4x - 2

Please answer this simple question !!!

Vlada [557]

A rational number is a number that can be written in form a/b where a and b are integers and b is not eual to 0

simplify eacy
$\sqrt{8}=2\sqrt{2}$
$\sqrt{16}=4$
we get

$\frac{2\sqrt{2}}{3}+4$
$\sqrt{2}$ is irrational
since we can't write $\sqrt{2}$ as a rational number, the entire phrase is irrational

anwer is irrational

Figure not drawn to scale.

DerKrebs [107]

Though you do not provide a diagram, I am going to give this a try by assuming that O is the center of the circle, OA is a radius, and angle AOB is a central angle that measures 88 degrees.

We want to find out the area of sector AOB. First, we need to find the area of the entire circle. The area of a circle is given by $A= \pi r^{2}$ and since the radius of this circle is equal to 1, the area is $\pi ( 1^{2} )= \pi$

Next we need to know what fraction of the circle sector AOB represents. The distance around the circle is 360 degrees but the central angle that intercepts arc AB is 88 degrees. That meas that the fraction of the circle the sector represents is given by $\frac{88}{360}= \frac{11}{45}$

We multiply this by the area to obtain $\frac{11}{45} \pi$ which is the area of the sector.
