Answer: Order will be F,D,C and Fourth Option is correct and  x = 10

Step-by-step explanation:

Since we have given that

\sqrt{6x+4}=8

We first transpose the square root to the right , so it becomes square of 8,i.e.

6x+4=8^2\\\\6x+4=64

Now, transpose 4 to the right so it will get subtract from 64 i.e.

6x=64-4\\\\6x=60

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

x=\frac{60}{6}\\\\x=10

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.

Identify the slope and y-intercept of each of the following lines. Then graph each line.
viktelen [127]

First <u>rewrite the equation</u> in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

\rightarrow \sf 8y = -2x+32

\rightarrow \sf y =\dfrac{ -2x+32}{ 8}

\rightarrow \sf y =\dfrac{ -2x}{ 8} + \dfrac{32}{8}

\rightarrow \sf y =\dfrac{ -1}{ 4}x + 4

<u>comparing</u> with y = mx + b

  • slope: -1/4     and   y-intercept: 4

x-intercept:          ( then y will be 0 )

\hookrightarrow  \sf -2x + 32 = 0

\hookrightarrow  \sf -2x  = -32

\hookrightarrow  \sf x  = 16

In order to graph the line

  • plot x = 16 on the x-axis     coordinate: (16, 0)
  • plot y = 4 on the y-axis     coordinate: (0, 4)
  • Then using a scale/ruler draw a straight line through this points.

Graph:
