Answer:

\frac{x + 2}{3}

Step-by-step explanation:

Replace y with f(x).

y = 3x - 2

Swap x and y and solve for y

x = 3y - 2

x + 2 = 3y

\frac{x + 2}{3}  = y

What’s the correct answer for this?
VMariaS [17]

Answer:

Second option is the correct answer

(x+11)^2+(y+6)^2 = 324

Step-by-step explanation:

x^{2} +12y+22x+y^2-167=0\\x^{2}+22x +y^2 +12y-167=0\\(x^{2}+22x +121)-121 +(y^2 +12y+36)-36-167=0\\(x+11)^2+(y+6)^2-324 = 0\\\huge\red{\boxed{(x+11)^2+(y+6)^2 = 324}}\\

Find the measures of EAF DAE and CAD
sdas [7]
You have to build an equation to find the answer,

angles in a straight line add upto 180° 
so your equation would be,

12x+30°=180°
      -30    -30
=12x=150°
   ÷12  ÷12
=x=12.5°

now find the measures of the angles by using 12.5 as x.

angle EAF= 2x
                 =2×12.5
                 =25° degrees

angle DAE= 4x
                 =4×12.5
                 =50°degrees

angle CAD=6x
                 =6×12.5
                 =75°degrees

check,
30+25+50+75=180°degrees

hope this helps.......
