So her benefits is basically 25,000(0.30). The total benefits would be $7,500.

There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.

First let's try solving for y since it's easier to start with.

Firstly we have to find an equation for x:

x-2y=2\\x-2y+2y=2+2y\\x=2+2y

Great, now we can use the substitution method to find the value of y using the first equation:

2x+3y=11\\2(2+2y)+3y=11\\4+4y+3y=11\\7y=7\\y=1

Now we know that y=1 we can solve the first equation we made:

x=2+2y\\x=2+2(1)\\x=4

And the answer is x=4 , y= 1\\(4,1)

Double check:

2x+3y=11\\2(4)+3(1)=11\\8+3=11\\11=11\\\\x-2y=2\\(4)-2(1)=2\\2=2

And that's our final answer! (4,1)

What is the translation of the point to its image? A (−1, 4)→ A' (3, 3)
Gala2k [10]

Answer:

We validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)

Step-by-step explanation:

Given

A (−1, 4)→ A' (3, 3)

Here:

  • A(-1, 4) is the original point
  • A'(3, 3) is the image of A

We need to determine which translation operation brings the coordinates of the image A'(3, 3).

If we closely observe the coordinates of the image A' (3, 3), it is clear the image coordinates can be determined by adding 4 units to the x-coordinate and subtracting 1 unit to the y-coordinate.

Thue, the rule of the translation will be:

A(x, y) → A' (x+4, y-1)

Let us check whether this translation rule validates the image coordinates.

A (x, y) → A' (x+4, y-1)

Given that A(-1, 4), so

A (-1, 4) → A' (-1+4, 4-1) = A' (3, 3)

Therefore, we validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)
