Answer:
- domain: [2, 6]
- range: [6, 18]
Step-by-step explanation:
The domain is the horizontal extent of the graph. When end points are involved, you have to be able to tell if they are included in the function definition, or not. Here, the solid dots mean both end points are included.
The graph extends horizontally from 2 to 6. You read this from the "x" scale at the bottom. As an inequality, the domain is written ...
2 ≤ x ≤ 6
In interval notation, it is [2, 6]. Square brackets are used to indicate the end point values are included.
__
The range is the vertical extent of the graph. This one extends from y=6 to y=18. You read this from the "f(x)" scale on the left. The range can be written as ...
6 ≤ y ≤ 18
[6, 18]
Answer:
80
Step-by-step explanation:
profit = revenue - expenses
revenue = $15 per hour = $15 * number of hours (n) = $15 * n
expenses = $490 + $45 + $65 = $600
we want profit to be 600 or more
15 * n - 600 = profit
profit ≥ 600
15 * n - 600 ≥ 600
add 600 to both sides to isolate the variable and its coefficient
15 * n ≥ 1200
divide both sides by 15 to isolate the variable
n ≥ 80
Jose must therefore work 80 or more hours, for a minimum of 80

Answer:
hello : x = 98°
Step-by-step explanation:
note :
sum of angles in polygonal is : ( n -2) × 180° ..... n : number of side
in this exercice : n = 7
sum of angles is : (7 -2 ) × 180° = 5× 180° = 900 °
x = 900° - ( 142° +110° +140° +142° +122°+146°) = 900° - 802°
x = 98°
