Answer:
2 1/4 times
Step-by-step explanation:
A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour. how many times as long in the morning did he work in the afternoon
Note that:
1 hour = 60 minutes
In the moring he worked 2/5 of an hour.
= 2/5 × 60 minutes
= 24 minutes
In the afternoon he worked for 9/10 of an hour
Hence:
9/10 × 60 minutes
= 54 minutes
How many times as long in the morning did he work in the afternoon?
This is calculated as number of minutes worked in the afternoon ÷ Number of minutes worked in the morning
= 54 minutes/24 minutes
= 2 6/24
= 2 1/4 times

Answer:
A. -1 ≤ x ≤ 3
Step-by-step explanation:
The range is the horizontal extent of the graph--the set of x-values for which the function is defined. Here, the graph extends from x = -1 to x = 3, with both end points included. The range is ...
-1 ≤ x ≤ 3
Answer:
8x + 5x = 13x
Step-by-step explanation:
Since these two can be added, you just add like normal and make sure you do not forget the x.
The point-slope form:
m - slope
(x₁, y₁) - the point
The formula of a slope:
We have the points (5, 4) and (2, -2). Substitute:
- <em>point-slope form</em>
<em>add 4 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 2x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
-------------------------------------------------------------------
From the table we have two points (1, 3) and (2, 7). SubstituteL
- <em>point-slope form</em>
<em>add 3 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 4x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
