Answer:
Domain is all real numbers.
Range is all real numbers.
Step-by-step explanation:
The domain is all the possible x values that are allowed.
The range is all the possible y values that are allowed.
Since this is a linear function, its graph is a straight line stretching from - infinity to infinity on both x and y axes, hence domain and range is all real numbers from - infinity to infinity.
This particular linear function (of form y = mx + c) has gradient m = 3 so slopes up to the right, and y-intercept c = - 5, an hence x-intercept 5/3.
The graph is sketched below and clearly extends indefinitely in terms of range and domain.

Answer:
Part A = C
Part B = 1/12
Step-by-step explanation:
Part A= this is because you need all the outcomes from the coin and from the dice joined together .
Part B= Because there is only one outcome that shows how you get a head on the coin and 6 on the dice.
Since the book was sold for 25.02.
The sell price = 24.
Tax = 25.02 - 24 = 1.02.
The rate is the percentage of the sell price.
= 1.02 / 24 * 100% Converting the 1.02 to fraction = 102 / 100
= (102/100) / 24 * 100
= 102 / 2400 * 100 Cancel the zeros at the top and bottom
= 102 / 24 * 1
= 102 / 24 2 into 102 = 51, 2 into 24 is 12
= 51 / 12. 3 into 51 is 17, 3 into 12 is 4.
= 17 / 4 Use your calculator.
= 4. 25
Tax rate = 4.25%. Cheers.
Answer:
x= 1 and y= -1
Step-by-step explanation:
I'm pretty sure it is the just substitution method that you need for this, which is how I solved it and I am confident.
