Answer:

B

Step-by-step explanation:

The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.

Be sure to clearly label each part of your response as Part A, Part B, and Part C.

Answer:

Part A: y = 3x

Part B: The relationship of y to x is y is 3 times as much as x.

Part C: (0,0), (1,3), (2,6), (3,9), (4,12)

Step-by-step explanation:

Part A: The product of x and 3 (3 times x) is (equals) y. So we can write this linear equation as y = 3x.

Part B: The linear equation is a representation of the relationship between y and x. Y is equivalent to three times x.

Part C: To create solutions to the linear equation, simply plug in a value of x to output a y.

x = 0 -> y = 3(0) = 0; (0,0)

x = 1 -> y = 3(1) = 3; (1,3)

x = 2 -> y = 3(2) = 6; (2,6)

x = 3 -> y = 3(3) = 9; (3,9)

x = 4 -> y = 3(4) = 12; (4, 12)

Cheers.

Solve x+2=1/2x-1 Please hurry!

vfiekz [6]

Answer:

<h2>X = - 6</h2>

Step-by-step explanation:

<h2><u />x + 2 = 1/2x - 1</h2>

$2 + 1 = \frac{1}{2}x - x$

$3 = - \frac{1}{2}x$

$x = \frac{ - 3}{ \frac{1}{2} } \\ x = \frac{ - 6}{1} \\ x = - 6$

6/8 is equivalent to 3/4. How can you use this to help you write 6/8 as a decimal?

Alexus [3.1K]

Answer:

0.75 is the answer

Step-by-step explanation:

6/8 is equivalent to 3/4

3 divided by 4 is 0.75

Since 6/8 is equivalent then it is also 0.75

Also 6/8 turn to 3/4 when both the numerator and denominator is divided by 2.

6 divided by 2 is 3

8 divided by 2 is 4
