3x + 12 = -3 What is the value of X

Answers

Answer 1

Answer:

x = -5

Step-by-step explanation:

i took algebra a couple years ago :)

Answer 2

Answer:

x=-5

Step-by-step explanation:

3x+12= -3

   -12    -12

(subtract 12 from both sides because you want the variable by itself)

3x= -15

(divide by 3 so you can get x completely by itself)

x= -5 (final answer)

HELP HELP HELP A triangle has two sides of length 14 and 18. What is the largest possible whole-number length for the third side?

Answers

The way you can do this is Pythagorean theorem. Since the hypotenuse has to be the highest part. So you would do 14^2 + 18^ = c^2 and then do that and you get 196 + 324 which is equal to 520 so then get the square root of that which is 22.8, but it says largest possible whole number length so you would put 22.

Answer:

x = [tex]\frac{6}{25}[/tex]

Step-by-step explanation:

Given

[tex]\frac{12}{x}[/tex] = 50 ( multiply both sides by x )

12 = 50x ( divide both sides by 50 )

[tex]\frac{12}{50}[/tex] = x , that is

x = [tex]\frac{6}{25}[/tex]

Rita is starting a running program. The table shows the total number of miles she runs in different weeks. What is the equation of the line of best fit for the data? State each number to the thousandths place.

Answers

Step-by-step explanation:

Y = 1.671 X + 4.699

The equation of best fit data is Y = 1.671 X + 4.699

What are fit equations?

Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.

The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.

We add the scale factor to each length of an image to get the scaled copy.
-True or False?

Answers

Answer:

false

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

original dimensions / scale of the drawing  = dimensions of the scale drawing

To scale an image, divide the original length by the scale

for example the length of the image is 100 and the scale factor is 4

the length of the scale copy = 100/4 = 25

Answer:

A. 38.5

Step-by-step explanation:

Since the angles <XWZ and <XYZ are congruent, <ZYW is just half of <XYZ, so you would just divide 77 in half to get your answer. It's a rhombus, so it works similarly to a square. If one side is congruent, the other is too.
