Answers

Answer 1

Answer:

x = 4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

-4(x + 2) = 4(2 - 2x)

Step 2: Solve for x

Divide -4 on both sides: -(x + 2) = 2 - 2xDistribute negative: -x - 2 = 2 - 2xAdd 2x on both sides: x - 2 = 2Add 2 on both sides: x = 4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -4(4 + 2) = 4(2 - 2(4))Multiply: -4(4 + 2) = 4(2 - 8)Add/Subtract: -4(6) = 4(-6)Multiply: -24 = -24

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.

What is the equation of the line that passes through the point (-6, -2) and has a
slope of 1/6

Answers

Answer:

y=1/6x-1

Step-by-step explanation:

Recall that the equation of a line is y = mx + b.

m is the slopeb is the y-intercept

We know the line passes through (-6, -2), so we substitute x and y in the equation of a line. We also know the variable m (the slope) is 1/6. It would look something like this: -2=(1/6)(-6) + b.

From here, we can solve for b:

b + (1/6)(-6) = -2

b - 1 = -2

b = -1

The equation of the line that passes through the point (-6,-2) with a slope of 1/6 is y=1/6x-1.

This is my first solution, let me know if I can improve on anything. Thanks, have a great day!

Step-by-step explanation:

Your problem is equivalent to

(x3 - 3x2 + x - 4)/(x-2)

The coefficients of the numerator are 1, -3, 1, -4.

The solution is as follows:

2 | 1 -3 1 -4 Set up the coefficients in decreasing power of x, and 2 is the divisor.

2 -2 -2

------------------

1 -1 -1 -6

Here are the steps:

(a) Bring down the leading coefficient of 1.

(b) 2*1=2. Add -3 and 2 to obtain -1.

(d) -1*2=-2. Add -2 and -4 to obtain -6

The quotient has the coefficients 1,-1,-1 so it is x2 - x - 1. The remainder is -6.

Answer :

The result is x2 - x - 1 - 6/(x-2).

You can verify that the answer is correct, because

(x-2)*(x2 - x - 1) - 6 = x3 - 3x2 + x - 4

Hope this helps you

What is the slope of a line parallel to the line whose equation is 6x + 3y = -54

Answers

The slope of the line parallel to the line is -2

What are linear equations?

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the slope of the line parallel to the line?

The line equation is given as

6x + 3y = -54

Subtract 6x from both sides

3y = -6x - 54

Divide through the equation by 3

So, we have

y = -2x - 17

A linear equation is represented as

y = mx + c

Where m represents the slope

This means that

m = -2

Parallel lines have the same slope

This means that the slope of the line parallel to the line is -2

Answers

Based on the fact that Mario increases by a scale factor of 2, the three points on the new Mario:

(7, 0)(0, 10.4)(4, 17.4)

What are the new points?

If Mario is increased by a scale factor of 2, then it means that all the points would be expanded by multiplying them by 2.

The first point would therefore be:

= 3.5 x 2 = 7

= 0 x 2 = 0

(7, 0)

The second point:
= 0 x 2 = 0

= 5.2 x 2 = 10.4

(0, 10.4)

The third point:
= 2 x 2 = 4

= 8.7 x 2 = 17.4

(4, 17.4)

The points on New Mario are:

(7, 0), (0, 10.4), and (4, 17.4)
