It should be B.
2x-x+3 = 8
x = 5
plug into second equation
y=5-3
y=2
(5,2)

Answer:
y=8.25x-15
Step-by-step explanation:
From the information provided, the algebraic expression will need to indicate that your earnings during the first week, y, would be equal to multiplying $8.25 for the number of hours, x, minus $15. According to that, the algebraic expression is:
y=8.25x-15
X=116
you do the equation to the left and then, you do the equation to the right and you subtract the answer from the right to left and there you get your answer
Answer:
Step-by-step explanation:
For this exercise it is necessary to remember that the area of a circle can be calculated with the following formula:
Where "A" is the area of the circle and "r" is the radius of the circle.
In this case, based on the information given in the exercise, you know that the circular plate has the following radius:
Therefore, knowing the radius, you can substitute them into the formula and finally, you must evaluate in order to calculate the area of the plate (Remember that you must use 3.14 for ).
Then, you get that this is:
