Answer:

The answer (using BEDMAS) is 27

Step-by-step explanation:

The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS

First solve the smaller bracket

18 + 2 = 20

So then it becomes 9 x [20 ÷ 5 - 1]

Do the division inside the bracket next

20 ÷ 5 = 4

Then it becomes 9 x [4 - 1]

Do then subtraction within the bracket

4 - 1 = 3

Then it becomes 9 x 3

Finally solve 9 x 3 which equals 27

Solve this linear system by graphing. Check the solution. <br> 3x+y=11<br> x-2y=6

alexandr402 [8]

In this system of equations, I'll do elimination. Ok, so what we are trying to do is to eliminate a variable, but we can't. So since -2y is negative, and y has a coefficient of 1 and is positive, let's multiply the first whole equation by 2.
2 times (3x+y=11) is 6x+2y=22. (I just used distributive property.) Now let's add from left to right.
6x plus x is 7x, 2y plus -2y is 0, and 22 plus 6 is 28. Now we have this simple equation, 7x=28. We can simply divide each side by 7, to get x as 4. So x=4 in this set of equations. Now all we need to do is plug x in the equation then solve for y. For this system of equations, I'll use the first equation, because it is easier. So I'll plug x as 4 into the equation to get 12+y=11. Now we can simply solve for y. 11-12 is -1, so y must equal -1. So y=-1. Therefore, x=4 and y=-1. Hope I helped.

Over the past several years, the owner of a boutique on Aspen Avenue has observed a pattern in the amount of revenue for the sto

NARA [144]

Answer:

f(x) = 10500sin(π/6(x -3)) +39500

Step-by-step explanation:

The average of the maximum and minimum revenue is the vertical offset of the function, parameter D.

D = (50,000 +29,000)/2 = 39,500

The amplitude of the function is the difference between the maximum and the offset.

A = 50,000 -D = 50,000 -39,500 = 10,500

The horizontal scale factor B is a number that will be equal to 2π when x-C = 12:

12B = 2π

B = π/6 . . . . . . divide by 12

The horizontal offset is such that revenue is neutral and increasing at the value x=C. That will be in the month of March, when x=3, so C=3.

Now we have all the parameters, so we can write the equation:

f(x) = 10500sin(π/6(x -3)) +39500
