Question seems to be incomplete. Here, Question could be -

"Twice the sum of a number and 3 is equal to three times the difference of the number and 9 find the number."

Algebraic expression consists of constant and variable. eg x, y, z etc.

Let the number be 'x'.
Now, applying condition
2(x+3) = 3(x-9)

2x+6 = 3x - 27
x = 21

Thus the required number is 21.

Answer:

you would simply calculate the slope for each, a graph it is easy because you simply get two points on the graph and solve for it (y2-y1/x2-x1), an equation if it is in slope intercept form, the coefficient of x is the slope, from a table you use a similar method to a graph except you grab two values/instances, let's say in a table the numbers are presented like this:

3   4

2   6

You would then simply do the same thing for solving for the slope (y2-y1/x2-x1). In this instance it would be 6-2/4-3=4/1

All of these would give you the rate of change as the slope is the rate of change.

Answer:

20,000

Step-by-step explanation:

Let's take it step-by-step

10 times greater than 2,000

10 x 2 = 20, 10 x 20 = 200, 10 x 200 = 2,000, 10 x 2,000 = 20,000

just remember to add a zero after each number so, if you have 10 x 20, just take the 2 and but a zero, 20, 10 x 20 = 200, Etc.

If you need more help let me know :)

Ten times greater than 2000 is 2000.

To find how much greater one quantity is to other just divide other quantity by one quantity.If how many times is given and have to find greater just multiply the given quantity by the given times.

In the given question 10 times greater than 2000 is 2000 multiplied by 10   = 20000

To reverse check divide 20000 by 2000 and the result should match the previous result you have obtained.

Answer:

You would subtract -12 from both sides!

Explanation:

The eqaution will become like this:

[tex]x^{2}[/tex] - 16x + 12 = 0

Then you would solve it with the Quadratic Equation formula.

Answer:

First, subtract 60 from each side of the equation.

Next, add 64 to each side of the equation to complete the square.

Now, write x² - 16x + 64 = -8 as (x-8)^2=-8

Take the square root of both sides to get the solutions.

Step-by-step Explanation

[tex]log \frac{3}{2} \\ \\ = log \frac{3 \times 4}{2 \times 4} \\ \\ = log \frac{12}{8} \\ \\ = log 12 - log 8 \\ \\ = 1.1 - 0.9 \\ \\ = 0.2 \\ \\ \huge \red{ \boxed{log \frac{3}{2} = 0.2}}[/tex]

Answer: 0.2

Step-by-step explanation:

We have to find [tex]log \frac{3}{2}[/tex].

We are given log 12 and log 8, the farthest.

Subtract to find the number you have to multiply by.

3 x 4 = 12 and 2 x 4 = 8.

Our next fraction will be [tex]log \frac{12}{8}[/tex]

Now, subtract log 12 (1.1) by log 8 (0.9)

1.1 - 0.9 = 0.2

So, the answer to the question is 0.2

Answer:

B. (3, -1)

Step-by-step explanation: I got a 100 on the test

The rule for a reflection across line y = -x: (x, y) → (-y, -x)

F(1, -3) → F'(3, -1)

The answer would be option B (3, –1).

A parallelogram defined as a special type of quadrilateral which has both pairs of opposite sides parallel and equal.

Coordinates of the vertices of a parallelogram are,

E(-3, -5), F(1, -3), H(2, -5), G(-2, -3)

Equation of a line about which this parallelogram was reflected is, y = -x

The rule for a reflection across line y = -x: (x, y) → (-y, -x)

That means when a point (x, y) is reflected across the line y = x, we find a new point (-y, -x)

By this rule new point by reflecting point F will be,

F(1, -3) → F'(3, -1)

Therefore, Option (B) will be the answer.

Answer:

1/6

Step-by-step explanation:

Side AB * scale factor = Side DE

72* scale factor = 12

Divide each side by 72

scale factor = 12/72

scale factor = 1/6

Option B is correct, 1/6 is the scale factor of triangle ABC to triangle DEF

A triangle is a three-sided polygon that consists of three edges and three vertices.

Dilation is a transformation, which is used to resize the object

The size by which the shape is enlarged or reduced is called as its scale factor.

DEF is dilated graph of ABC

Let us take any side of ABC and its corresponding side to find the scale factor

Side AB × scale factor = Side DE

72×scale factor = 12

Divide each side by 72

scale factor = 12/72

scale factor = 1/6

Hence, 1/6 is the scale factor of triangle ABC to triangle DEF
