Remember, you can do anything to an equation as long as you do it to both sides


and when multiply or divide by a negative in inequalities, flip the direction of the sign

12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4



-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4

What is the answers to the question: Which rational expression is undefined when x = 0?
Rom4ik [11]

Answer:

option D

\frac{4x-8}{-2x^2}

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

<h3>1)</h3><h3>\frac{5x^2-4}{3x-3}</h3>

\frac{5(0)-4)}{3(0)-3}

-4/-3 = 4/3

<h3>2)</h3><h3>\frac{6x^2}{9x-3}</h3>

\frac{6(0)}{9(0)-3}

0/-3 = 0

<h3>3)</h3>

\frac{8x+6}{-x^2+1}

\frac{8(0)+6}{-0+1}

6/1

6

<h3>4)</h3>

\frac{4x-8}{-2x^2}

\frac{4(0)-8}{-2(0)}

<h3>-8/0</h3><h3>undefined</h3>

Simplify <br> -4x+2x2-x2+5-3x
Serga [27]

Answer:

9 - 7x - x²

Step-by-step explanation:

-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²

I arranged the like terms together so it is easier to do the calculations.

-4x-3x+2x2+5-x² = -7x+4+5-x²

Simplify.

-7x+4+5-x² = 9-7x-x²

Y=2x-1<br> y=1/2x+4<br> find the solution to the system equations
Evgesh-ka [11]

Answer:

x=10/3 y=17/3

Step-by-step explanation:

Use substitution to solve your equation. Plug in y=2x-1 into y=1/2x+4. This makes (2x-1)=1/2x+4. Simplify this to get 3/2x-1=4. Simplify it again to get 3/2x=5. No one likes fractions so multiply both sides by 2 to get 3x=10. Simplify this and get x=10/3. Plus 10/3 into one of the equations. You can pick anyone but I picked y=2x-1. Because you know x=10/3, you put y=2(10/3)-1. Simplify this and get y=20/3-1. Convert 1 into a fraction and get y=20/3-3/3. Simplify this and get y=17/3.

Therefore,

x=10/3 y=17/3

Hoped this helps you

Rewrite in rectangular form: r=5
SVETLANKA909090 [29]

Answer:

x  ^2+ y^ 2 = 25

Step-by-step explanation:

Square both sides:

r ^2 = 5^ 2

Substitute  x ^2 + y^ 2  for  r ^2 :

x ^2+ y ^2 = 5 ^2

Insert the center -0 into the x and y terms:

( x − 0 )^ 2 + ( y − 0 ) ^2 = 5 ^2

This is the standard form for a circle whose center is  ( 0, 0 )  and the radius is 5.
