Answer:
Domain [-4,4]
Range [-2,2]
Step-by-step explanation:
The domain is the x-values of the graph and the range in the y-values. When writing domain and range it should be from least to greatest. So to find the domain find the lowest x-value on the graph and then the highest. Next, do the same for y-values. Finally, either surround each value with parentheses or bracket, the difference is that brackets mean that value is included, while parentheses mean that value is not actually on the graph.
In this case, the lowest x-value is -4 and the highest is 4, both values are included as signified by the closed circles, therefore the domain is [-4,4]. The lowest y value is -2 and the highest is 2, both are included, therefore the range is [-2,2].
Answer:
Step-by-step explanation:
we have
----> equation A
----> equation B
Multiply the equation B by 2 both sides
------> equation C
Adds equation A and equation C
Find the value of y
the solution is the point
The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8
The situation forms a right angle triangle.
<h3>How to find an angle in a right triangle?</h3>
The angle R can be found as follows:
using trigonometric ratios,
sin R = opposite / hypotenuse
Therefore,
opposite sides = 6
hypotenuse = 8
sin R = 6 / 8
R = sin⁻¹ 6 / 8

Notes before we start:
Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.
Explanation:
Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.
15 * 40 * 2 = $1,200
Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.
Answer:
Job B pays better.
Best of Luck!
