−1/5 (x − 4) = −2

-1/5x - 21/5 = -2
-21/5 + 2 = -1/5 x
- 4 1/5 + 2 = -1/5 x
-2 1/5 = -1/5 x
-11/5 = - 1/5x
-11/5 ÷ 1/5 = x
-11/5 x 5/1 = x
-55/5 = x
-11 = x

What is the solution to the equation 5x + 2y = -9
anyanavicka [17]

In order to find which one of the given points is a solution to the equation, we need to plug each point in the equation and check which one fits in .

The equation is :

5x+2y=-9

a.(2,-4)

5x+2y=-9

LHS: 5x+2y

Plugging (2,-4) in this,

5(2) +2(-4) = 10-8 =2

RHS : -9

LHS ≠RHS

So (2,-4) is not the solution.

b.(-1,2)

5x+2y=-9

LHS: 5x+2y

Plugging (-1,2) in this,

5(-1) +2(2) = -5+4 =-1

RHS : -9

LHS ≠RHS

So (-1,2) is not the solution.

c.(-2,5)

5x+2y=-9

LHS: 5x+2y

Plugging (-2,5) in this,

5(-2) +2(5) = -10+10 =0

RHS : -9

LHS ≠RHS

So (-2,5) is not the solution.

d.(1,-3)

5x+2y=-9

LHS: 5x+2y

Plugging (1,-3) in this,

5(1) +2(-3) = 5-6=-1

RHS : -9

LHS ≠RHS

So (1,-3) is not the solution.

None of the given options is a solution to the given equation.

The figure, polygon ABCD is dilated by a factor of 2 to produce A B C D with the origin as the center of dilation
cestrela7 [59]

In the polygon ABCD, the production of point A' and point D' is (-2,-2)  and (4,-2) respectively.

<h3>What is the transformation rule?</h3>

In coordinate planes, the rule of transformation involves interchanging the x and y values on the plane such that:

\mathbf{(x,y) \to  (k_x, k_y)}

where;

  • k = scale factor

From the given information:

  • The scale factor = 2
  • the origin as a center of dilation for image vertices = (0, 0)

Now, using the coordinate vertices:

  • A = (-1, -1)
  • D = (2, -1)

The corresponding coordinate of the image vertices is as follows:

A(-1,-1) → A'(2 × (-1), 2 × (-1))

A' = (-2,-2)

D(2,-1) → A'(2 × (2), 2 × (-1))

D' = (4,-2)
