Answer:

(3x+2)< -7  or   (3x+2) > 7

Step-by-step explanation:

we have

\left|3x+2\right|>7  

Divide the absolute value inequality into two inequalities

<em>First inequality</em> (positive value)

(3x+2) > 7

<em>Second inequality</em> (negative value)

-(3x+2) > 7

Multiply by -1 both sides

Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so

(3x+2)< -7

therefore

The compound inequality that can be used is

(3x+2)< -7  or   (3x+2) > 7

The area of a traingle is \frac{1}{2}bh
So we need to know the base and the height
To work out the sides of a right angle triangle we can use a²+b²=c
c is the hypotenuse and a and b are the other sides
Because this triangle is isoceles we know that a and b are the same

a²+b²=c²
a²+a²=c²
2a²=c²
2a²=(x√6)²
2a²=(x√6)(x√6)
2a²=x²+x√6+x√6+6
2a²=x²+x√6+x√6+6
a²=\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{2}
a=\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}

A=\frac{1}{2}bh
A=\frac{1}{2}a*a
A=\frac{1}{2}×\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}×\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}
A=\frac{1}{2}×\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{2}
A=\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{4}

Choose the equations that are not linear equations. -x - y = 2 x 2 + y = 4 - y 3 = 1 x = 5
NeX [460]
X² + y = 4 and -y³ = 1x -5 are not linear equation because they contain a variable with a exponents. These types of equation are called quadratic equations.

Evaluate -x+4y when -x=-4/5 and y= 1/3 write your anwser as a fraction or mixed number
Bogdan [553]

Answer:

\frac{8}{15}

Step-by-step explanation:

The given expression is

-x+4y

We have to find the value of given expression when -x=-4/5 and y= 1/3.

Substitute -x=-4/5 and y= 1/3 in the above expression, to find the value of given expression when -x=-4/5 and y= 1/3.

-\frac{4}{5}+4(\frac{1}{3})

After multiplication we get

-\frac{4}{5}+\frac{4}{3}

Taking LCM, we get

\frac{3(-4)+5(4)}{15}

\frac{-12+20}{15}

\frac{8}{15}

Therefore, the value of given expression is \frac{8}{15}.
