Verdich [7]3 years ago
4 0

Answer:

0 = x

Step-by-step explanation:

  1. ½x - 4 = 4x - 4 [Use the Distributive Property of Multiplication.]
  2. -3½x - 4 = -4 [Move -4x to the left side of the equivalence symbol.]
  3. -3½x = 0 [Move 4 to the right side of the equivalence symbol.]
  4. 0 = x [Divide by -3½.]

I am joyous to assist you anytime.

Answer:

Actual mean: 223 pages

Predicted mean / estimate: 225 pages

Explanation below

Step-by-step explanation:

Mean = total amount ÷ # of numbers

155 + 214 + 312 + 198  + 200 + 170 + 250 + 260 + 215 + 256

Add

2,230

# of numbers = 10

2,230 ÷ 10 = 223

The exact mean is 223

If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.

Actual mean: 223 pages

Predicted mean: 225 pages

Hope this helps :)

Which of the following best describes the graph above?
Maru [420]

Answer: C

Step-by-step explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Hope this helps! :)

Indicate the equation of the given line in standard form. The line with slope and containing the midpoint of the segment whose e
Tems11 [23]

Answer:

x + y = -1

Step-by-step explanation:

To write the equation of a line, find the slope and use it with a point in the point slope form.

You can find the slope using the slope formula.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{5--3}{-6-2} = \frac{8}{-8}=-1

Substitute m = -1 and the point (2,-3) into the point slope form.

y - y_1 = m(x-x_1)\\y --3 = -1(x-2)\\y+3=-1(x-2)

Convert to standard form by applying the distributive property and rearranging the terms.

y+3 = -1(x-2)

y + 3 = -x + 2

x + y + 3 = 2

x + y = -1

The equation y=1125(1.034)^x can be used to approximate the number of cell phone users
Vsevolod [243]

Answer: B

Step-by-step explanation:

The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.

So the initial number of cell phone users in 2000 was 1125.
