3x -(-2-4x)=
What does this equals??

Answers

Answer:

7x + 2

Step-by-step explanation:

Original Equation: 3x − ( −2 − 4x)

First, we distribute the negative sign:

= 3x + (−1) (−2−4x)

=3x + (−1)(−2) + (−1)(−4x)

= 3x + 2 + 4x

Using the communitive property of addition, we can write:

= 3x + 4x + 2  (Instead of 3x + 2 + 4x)

Combining like terms, we get:

= (3x + 4x) + 2

= 7x + 2

What are the solution(s) of x squared minus 4 = 0

Answers

Answer:

x=2 or x= -2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

=  ±  2  =  { x 1 = − 2

              x 2 = 2

Answer:

X=2 or X=-2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

How many presents would shelia wrap in 6 hours if she wrapped 4 presents every 4 minutes?

Answers

Answer:96

Step-by-step explanation:

Well 4 presents every 4 minutes is the same thing as 1 present every 1 minute.
So now, we know that every 1 minute, she wraps 1 present.
Now, in 6 hours, there are 360 minutes so, we would simply multiply 1 present by 360 minutes which gives us the answer of 360 presents wrapped in 6 hours.

Identify the x- and y-intercepts of the equation
4x - y = 8

Answers

Answer:

[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]

Step-by-step explanation:

A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,

[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]

Hence on comparing to standard form we get

x intercept as (2 , 0 )y intercept as (0,-8)

Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .

Answer:

x = (2,0)

y = (0,-8)

Step-by-step explanation:

Remember than an intercept always has the other number as 0.

Let's put this in standard form of a linear equation, or y = mx + b

4x - y = 8

-y = -4x + 8

y = 4x - 8

"b" is the y intercept. The y intercept is -8, or (0,-8)

Now, to find the x intercept, all we have to do is substitute 0 for y.

0 = 4x -8

8 = 4x

2 = x

The x intercept is 2, or (2,0)
