4(x-3)-5(x+1)=3 which statement show a correct next step in solving the equation

2 answers:

5 0

The first thing you should do to solve this equation would be to distribute.
After distributing it would look like this
4x-12-5x-5=3
Just gonna finish this for no reason
-x-17=3
+17 +17
-x = 20
x = -20

4(x - 3) - 5(x + 1) = 3

4x - 12 - 5x - 5 = 3

-12 - 5 - 3 = 5x - 4x

x = -20

Knight and Haslam (2010) found that office workers who had some input into the design of their office space were more productive

sleet_krkn [62]

Answer:

1. Option A

2. Option A

Step-by-step explanation:

The independent variable is the one which affects the other variable. Here two variables "design of office space" and "control by managers" control the Productivity and well-being of the workers.

Hence, the independent variable is Control of the office manager

Option A

2. The dependent variable is the one which gets affected by the independent variable and in this case it is the Productivity and well-being of the workers.

Option A

Write the slope-intercept form of the equation of the line described.

Ad libitum [116K]

Given the line

$y=-x+2$

We know that the slope-intercept form of the line equation is

$y=mx+b$

here

m is the slope and b is the intercept

Thus, the slope = -1

We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1

Using point-slope of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -1 and the point (4, 0)

$y-0 = -1 (x-4)$

Writing in the slope-intercept form

$y = -x+4$

Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:

$y = -x+4$

Note: Your line is a little bit unclear. But, I am assuming the

ine is: y = -x-1

Given the assumed line

y = -x-1

We know that the slope-intercept form of the line equation is

$y=mx+b$

here

m is the slope and b is the intercept

Thus, the slope = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Using point-slope of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 1 and the point (4, 3)

$y - 3 = 1 (x-4)$

Writing in the slope-intercept form

y-3 = x-4

y = x-4+3

y = x - 1

Thus, the slope-intercept form of the equation of the line equation perpendicular to y = -x-1 will be:

y = x - 1
