Answer:

k = 0

Step-by-step explanation:

-2k = 8k + 7k

Add similar elements:

-2k = 15k

Subtract 15k from both sides:

-2k - 15k = 15k - 15k

Simplify:

-17k = 0

Divide both sides by -17:

17k/-17 = 0/-17

k = 0

I wasn't sure if you wanted me to solve for k or combine the like terms.

Describe how you can use the information in a table showing a linear relationship to find the slope and y-intercept for the equa

maks197457 [2]

If you have a table that tells you the (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.

Please Answer and Show your Work: <br><br> 4x/16 - 3/8 - x/16 = 3/16

Galina-37 [17]

4x/16 - 3/8 - x/16 = 3/16

x/4 - 3/8 - x/16 = 3/16

3x/16 - 3/8 = 3/16

Add 3/8 on both sides

3x/16 = 9/16

Then multiply 16 on both sides

3x = 144/16

3x = 9

Divide 3 on both sides

x = 3

Which list shows fraction that ALWAYS result in a terminating decimal for values of n > 0? A) 1/11, 1/121, 1/1331 . . . , 1/1

Alla [95]

Answer:

B) 1/10, 1/100, 1/1000 . . . , 1/10n

Step-by-step explanation:

Comparing all the options given:

A) 1/11, 1/121, 1/1331 . . . , 1/11n

Finding the decimal of the first term,

1/11 = 0.0909090 (never ending decimal place)

B) 1/10, 1/100, 1/1000 . . . , 1/10n

Finding the decimal of the first term,

1/10 = 0.01 (ended decimal place)

C) 1/6, 1/36, 1/126 . . . , 1/6n

Finding the decimal of the first term,

1/6 = 0.16666667 (never ending decimal place)

D) 1/3, 1/9, 1/27 . . . , 1/3n

Finding the decimal of the first term,

1/3 = 0.33333333 (never ending decimal place)

What is the slope of the the line that goes through (4,3) and (8,5)

TEA [102]

Formula to find the slope:

m = y2-y1 / x2-x1

(4,3); (8,5)

m= 5-3 / 8-4

m = 2/4

m = 1/2

Therefore, the slope of the line that passes through these points is 1/2
