ANSWER

( {y  - 8)}^{2}  =  - 28(x + 5)

EXPLANATION

The given parabola has directrix x=2.

This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.

The equation of such parabola is of the form:

( {y  - k)}^{2}  = 4p(x - h)

where (h,k)=(-5,8) is the vertex.

|p|  = | - 2 - 5|  = 7

p =  \pm7

But the parabola opens to the left.

p=-7

The equation now becomes

( {y  - 8)}^{2}  = 4( - 7)(x   -  - 5)

( {y  - 8)}^{2}  =  - 28(x + 5)

3x + 2 =11 (solve for x)
torisob [31]

Answer:

x=3

Step-by-step explanation:

first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.

3x+(2-2)=11-2

3x=9

now we have to isolate the variable we can divide both sides by 3:

3x/3=9/3

x=3

and you get the answer that x is 3
