Answer:

x = -3

Step-by-step explanation:

Step 1: Write out equation

6 - 4x = 6x - 8x + 12

Step 2: Combine like terms (x)

6 - 4x = -2x + 12

Step 3: Add 4x on both sides

6 = 2x + 12

Step 4: Subtract 12 on both sides

-6 = 2x

Step 5: Divide both sides by 2

-3 = x

Step 6: Rewrite

x = -3

Answer:

The answer is x= -3

Step-by-step explanation:

6 - 4x = 6x - 8x + 12

First, add like terms. (6x-8x)

6-4x=-2x+12

Then "add" 4x to both sides.

6=2x+12

Then subtract 12 from both sides.

-6=2x

The final step is to divide. Divide 2 from both.

Your answer is x= -3

I hope this helps!!!

Determine the slope of the line that has the points (-5, 8) and (-5, 3).

Anuta_ua [19.1K]

Answer:

Option D : Undefined

Step-by-step explanation:

Given points (-5,8) and (-5,3) lies on a line.

Slope of a line is given by:

m = $\frac{y_2-y_1}{x_2-x_1}$

$m = \frac{3-8}{-5-(-5)}\\\\m=\frac{-5}{0}$

Anything divided by zero is undefined.

Therefore,

Option D is the correct answer.

The period is.......

Leni [432]

<h3>Answer: 2.244 seconds</h3>

Explanation:

The x coordinate of the left peak point is x = 1.870, and its neighboring peak point has an x coordinate of x = 4.114

The difference is 4.114 - 1.870 = 2.244

The period is 2.244 seconds, which is the time it takes to go from one peak to another adjacent. This is the same as going from one valley point to a neighboring valley point.

How do i solve this?

dangina [55]

$\text{Given that, f(x) = 2x+5}\\\\f(-1) = 2(-1)+5 = -2+5= 3\\\\f(2) = 2(2)+5 = 4+5 = 9\\\\f(0) =2(0)+5 = 0+5=5\\\\f(z) = 2z+5$

A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant prod

-Dominant- [34]

Answer:

Step-by-step explanation:

Given that a farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces

When we consider this graph as a straight line, the two points lying on the line would be

(30, 30) and (34, 28) taking n as horizontal and y vertical

Using two point equation we find that

the equation of the line is

$\frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1}$

Substitute the points as x =n

$\frac{y-30}{28-30} =\frac{x-30}{34-30}\\y-30 = -0.5(x-30)\\y = -0.5x+45$

is the linear relationship between n and y

Ann [662]

Answer:

4xy+24y^2−7x−38y−7

Step-by-step explanation:

(-7+4y) (6y+x+1)

-7*6y= -42y

-7*x= -7x

-7*1= -7

4y*6y= 24y²

4y*x= 4yx

4x*1= 4y
