Makovka662 [10]

Answer: See explanation. Hope this helps, please consider making me Brainliest.

Step-by-step explanation:

To find the rate of change, subtract then divide. This is especially a good strategy when you have the x and y values when x = 0:

604 - 460 = 144

144 divided by 18 =

8

Therefore, the rate of change is 8. We can even go further to create an equation for this:

y intercept = 460 (because 0 multiplied by the rate of change would be 0).

slope = 8

Slope-intercept form: y = mx + b --> y = 8x + 460

Hope this helps, please consider making me Brainliest.

Determine which equations below, when combined with the equation 3x-4y=2, will form a system with no solutions. Choose all that
svetoff [14.1K]
Two equations will not have solution if they are parallel and have different y-intercepts. Parallel lines have the same slope. In a slope-intercept form, the equation of the line can be expressed as,       
 
        y = mx + b 

where m is slope and b is the y-intercept.

Given: 3x - 4y = 2
Slope-intercept: y = 3x/4 - 1/2

A. 2y = 1.5x - 2
Slope-intercept: y = 3x/4 - 1

B. 2y = 1.5x - 1
Slope-intercept:  y = 3x/4 - 1/2

C. 3x + 4y = 2
Slope-intercept:  y = -3x/4 + 1/2

D. -4y + 3x = -2
Slope-intercept: y = 3x/4 + 1/2

Hence, the answers to this item are A and D.

If data for a time series analysis are collected on an annual basis only, which pattern can be ignored? a. horizontal b. seasona
ddd [48]

If data for a time series analysis are collected on an annual basis only, then the option(b) seasonal pattern can be ignored

Time series analysis is a specific way of analyzing a sequence of data points collected over an interval of time

The seasonal pattern is refers to the seasonal characteristics of the time series data. It is the predictable pattern that repeats at a certain frequency within one year, such as weekly, monthly, quarterly, etc.

A horizontal pattern exists when the data fluctuate randomly around a constant mean over time.

A trend pattern exists when there is a long-term increase or decrease in the series.

The cyclical component of a time series refers to fluctuations around the trend, excluding the irregular component, revealing a succession of phases of expansion and contraction

Here, the data for a time series analysis are collected on an annual basis, so the seasonal pattern can be ignored
