Answer:

k=13.8

Step-by-step explanation:

Given function:

2.5k+47.4=81.9
to find k..

Subtract final and middle value:

$81.9-47.4= 34.5$

Divide by 2.5:

$34.5*2.5=13.8$

Therefore, k=13.8..

What is the length of side x? (possibly use similar triangles)

weeeeeb [17]

Law of Sines

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

$\frac{sin(90)}{14.6} = \frac{sin(45)}{x}$

Cross multiply

x*sin(90) = 14.6sin(45)

x = 14.6sin(45)

x = 10.3

Use pencil and paper to create a table of values for the equation, x - 2y = 6. Rearrange the equation into the y = mx + b form.

Lunna [17]

Answer:

y = 1/2x -3

x=-2 ⇒ y = -4

x=-1 ⇒ y = -3.5

x=0 ⇒ y = -3

x=1 ⇒ y = -2.5

x=2 ⇒ y = -2

Step-by-step explanation:

Hi, to answer this question we have to isolate y:

x - 2y = 6

-2y =6-x

y = (6-x)/-2

y = -3+1/2x

y = 1/2x -3

Now, we have to create a table with the next values (see attachment)

x=-2 ⇒ y = 1/2x -3 = 1/2(-2)-3= -4

x=-1 ⇒ y = 1/2x -3 = 1/2(-1)-3= -3.5

x=0 ⇒ y = 1/2x -3 = 1/2(0)-3= -3

x=1 ⇒ y = 1/2x -3 = 1/2(1)-3= -2.5

x=2 ⇒ y = 1/2x -3 = 1/2(2)-3= -2
