The book is $8.50, so all you need to do is multiply 8.5 * 0.06 (the 6% sales tax in decimal form)

8.5 * 0.06 = .51

Then add that to $8.50

$8.50 + $0.51 = $9.01

Then subtract from $10

$10 - $9.01 = $0.99

99 cents in change

On a coordinate plane, 2 lines are shown. Line A B has points (negative 4, negative 2) and (4, 4). Line C D has points (0, negat
klasskru [66]

Answer:

Option A) They are parallel because their slopes are equal.

Step-by-step explanation:

We are given the following in the question:

Line AB:

(-4, -2), (4,4)

Line CD:

(0,-3), (4,0)

Formula to calculate slope =

(x_1, y_1), (x_2, y_2)\\\\\\text{Slope} = m = \dfrac{y_2 - y_1}{x_2 - x_1}

Slope of AB =

(-4, -2), (4,4)\\\\m_{AB} = \dfrac{4-(-2)}{4-(-4)} = \dfrac{6}{8} = \dfrac{3}{4}

Slope of CD =

(0,-3), (4,0)\\\\m_{CD} = \dfrac{0-(-3)}{4-0} = \dfrac{3}{4}

Thus,

m_{AB} = m_{CD}

Thus, the two lines are parallel.

Option A) They are parallel because their slopes are equal.

       Upon asking I got the rest of the information needed to answer this question.

-> Which one becomes a repeating decimal?

Your answer is D. 1/9.

       1/9 = 0.111111111111111111111111111111111 ... or 0.1 repeating. It can be written with a line over the 1 asyou can see in the attached.

PLEASE HELP ME<br> Use the function below to find f(2).<br><br> f(x) = 1/3 x 4^x
Anna71 [15]

f(2) This means that x is 2, so you plug in 2 for x in the equation

f(x)=\frac{1}{3} (4^x)

f(2)=\frac{1}{3}(4^2)

f(2)=\frac{1}{3} (16)

f(2)=\frac{16}{3}


Your answer is D
