Answer:

x=4

Step-by-step explanation:

A vertical line has an undefined slope

Vertical lines are of the form

x=

This passes through the point

(4,7)  so it must go through x=4

x=4

<h3>Answer is   x = 4</h3>

There is no y as part of the equation. It is a vertical line through 4 on the x axis. Every point on this line has an x coordinate of 4. Recall that all vertical lines have undefined slopes. I picked 4 because it is the x coordinate of the given point (4,7).

Answer:

By rounding up of the constant and coefficient terms, we have;

The line of best, fit is y = 1.23 + 3.46 × 10⁻²·x

Step-by-step explanation:

The table for the data on the number of movie admissions each year is presented as follows;

Year, x                                             {}                      Admission, y

0                                                      {}                         1.24

2                                                       {}                        1.26

4                                                      {}                         1.39

6                                                      {}                         1.47

8                                                      {}                         1.49

10                                                      {}                        1.57

Using a graphing calculator, we have that the line of best fit is given by the following equation;

y = 1.23047619048 + 3.45714285714 × 10⁻²·x

Which is approximately, y = 1.23 + 3.46 × 10⁻²·x

What is 8 groups of0.32?
Lelechka [254]
Okay! In order to find 8 groups of .32 you'd simply divide them. So:

[.32 ÷ 8] = .04

To check you multiply:

[8 x .04] = .32.

The answer is .04
