I WILL GIVE BRAINLIEST Solve the equation: x/−4 + 6 = −6.5

konstantin123 [22]

Answer:

x = 50

Step-by-step explanation:

The first step is to subtract 6 from both sides:

$\frac{x}{-4} +6 = -6.5$

- 6 - 6

___________

$\frac{x}{-4}$ = -12.5

The fraction $\frac{x}{-4}$ , is really just $\frac{1}{-4} x$ :

$\frac{1}{-4} x$ = -12.5

Multiply both sides by -4:

x = 50

A line has a slope of -2 and a Y intercept of -3. Graph the line using the slope and y-intercept. Which of the following points

nikdorinn [45]

<h2>Greetings!</h2>

Answer:

(1.5 , 0) , (-6 , 9) , (3 , -9)

Step-by-step explanation:

First, you need to find the equation of the line, which is:

y = mx + c

Where m is the gradient (or slope) and c is the y-intercept. Simply replace these values with the one given to you:

y = -2x -3

Now, simply draw this line by finding two points,

x = 0

y = -2(0) - 3

y = -3 when x = 0

When x = 3

y = -2(3) - 3

y = -9 when x = 3

Now you can use these points to plot the graph. (attacthed a screenshot of it)

Now simply find which given co-ordinates fit on the line. The points on the line are:

(1.5 , 0) , (-6 , 9) , (3 , -9)

<h2>Hope this helps!</h2>

Which system of equations is graphed on this coordinate plane

Allisa [31]

Answer:

y=(3x/2)+3 and y=(-1x/2)-1

Step-by-step explanation:

So what I did was use rise/run to find the slope of the equation. Let's focus on the line going from the bottom left to the top right corner. For this line, I would start on (-2,0) which is one of the points plotted on your number line and count how much it is away from (0,3). You should get 3 units. After this, count how much it is to the right which is 2 units. Now, use rise/run to find the slope. 3/2, therefore the slope of the line is 3x/2. Now all we need is the y-int. For the Y int, all we have to do is see where the line touches the Y-axis which in this case is at (0,3). So your y-int would be 3. Now we can use this information to craft an equation in the form y=mx+b, m being the slope and b being the y int. We should get y=(3x/2)+3. Now repeat this with the other line to find the equation, but be careful!!! It has a negative slope.

Which of the following are variables are categorical, if any? (check all that apply)

alukav5142 [94]

Answer:

A) The brand of cars driven by Harvard instructors

C) The types of plants growing in yellowstone

Step-by-step explanation:

Categorical and numerical variables:

Numerical data can be expressed with the help of numerical.
Categorical data cannot be expressed by numerical.
They do no have any particular value.
They are the non-parametric data.
Categorical data are also known as qualitative data.

A) The brand of cars driven by Harvard instructors

Since the brands cannot be expressed in numerical, it is a categorical variable.

B) The age of randomly selected biology students.

The age of student are expressed in whole numbers or decimals. Thus, it is a numerical data.

C) The types of plants growing in yellowstone

Again, the type of plants cannot be expressed with the help of numerical. Thus, it is a categorical variable.
