Viefleur [7K]

Answer:

Step-by-step explanation:

First, to get the rate, we divide 36% by 100 to get point 36. Since the formula is A =P(1+Interest rate/ How many units its being compounded)^ Time x How many times its being compounded. It would make the equation 2500(1+.36/4)^Compounded once which is 1 x 4 = A.

Hope this helps.

The graph of 3x - 2y = 6 does not pass through (4, -3) (4/3, -1) (-2, -6)
german

Answer:

(4,-3)

Step-by-step explanation:

If the line passes through a point, the coordinates of the point will verify the equation of the line.

So, let's see if each of the coordinates verifies the equation 3x - 2y = 6

A. (4,-3) means x=4 and y = -3

so 3x - 2y  becomes 3(4) - 2(-3) = 12 - -6 = 12 + 6 = 18

B. (4/3, -1) means x = 4/3 and y = -1

so 3x - 2y becomes 3(4/3) - 2(-1) = 4 - -2 = 4 + 2 = 6

C. (-2,-6) means x= -2 and y = -6

so 3x - 2y becomes 3(-2) - 2(-6) = -6 - -12 = -6 + 12 = 6

Verified that the line passes by the last two points but not the first one.

Carlie's Cell Phone Store owes a total of $144,627 in taxes.

1.) $1,287,684 - $598,982 = $688,702
Due to Tax Cuts and Jobs Act of 2017, corporate tax rate is fixed at 21%. Hence:

2.) $688,702 * .21 = $144,627.42 or $144,627
