Answer:

x = 8

Step-by-step explanation:

                                                             √3                  4√3

Note that cos 30 degrees (which is ---------) equals ---------  

                                                                2                      x

which simplifies to:

    1         4

  ----   = -----    

    2         x

so that x = 8

Answer:

\cos(30)  =  \frac{ \sqrt{3} }{2 }  =   \frac{4 \sqrt{3} }{x}  \\ x = 8 \sqrt{3}  \div  \sqrt{3}  = 8

Put y-x=-8 of a line into slope-intercept form, simplifying all fractions.
grigory [225]

Answer: y= x-8

Step-by-step explanation:

  • Slope intercept form has a general formula of y=mx +b
  • m represents the slope of the line
  • b represents the value of the lines y-intercept

  • the equation must be rearranged into the general formula by isolating for 'y'

y-x=-8

  • to remove the x from the left side of the equation the opposite operation must be done to both sides

y-x+x=-8+x

  • the negative and positive x cancel out on the left side, leaving us with the equation with y by itself
  • now you can rearrange to put the equation into y=mx+b

Final Answer: y=x-8
