1st multiply the top equation by -1 to get -3x - y = -17 then add the 2 equations together to get:

4x + y - 3x - y = 18 - 17
x = 1 (simplified down)

Now plug the 1 into either equation
4(1) + y = 18
4 + y = 18
y = 18 - 4 = 14

Your point is (1, 14)

Readme [11.4K]

Answer:

The total weight of both suitcases is 53 pounds.

Step-by-step explanation:

Write an expression that you can use to find the weight of the blue suitcase.

b = 3/4 * g - 10

Then explain how you can find the total weight of both suitcases if the green suitcase weighs 36 pounds.

b + g = 3/4 * g - 10 + g = 7/4 * g - 10 = 7/4 * 36 - 10 = 53 pounds

Answer:

1\frac{7}{20}

Step-by-step explanation:

Step one

Given data

On  Monday, Jesse drank 3/4 of liter of water before jogging

and drank 3/5 of liter after jogging

In all, Jesse drank 3/4 and 3/5 liters of water

= 3/4+3/5

the lcm is 20

=15+12/20

=27/20

in mixed numbers(i.e a whole and a fraction together we have) we have

1\frac{7}{20}

Which rule yields the dilation of the figure QRST centered at the origin?
denis-greek [22]

A) (x, y) → (3x, 3y)

<h2>Explanation:</h2>

When you dilate an object, you enlarge or reduce the size of it. To do this, we need a scale factor which allows us to make the object larger or smaller depending on the value of that factor. Let's call this factor as k, then it is true that:

  • If k > 1, the object will be larger than the original one.
  • If k < 1, the object will be smaller than the original one.

If the dilation is performed centered at the origin, then corresponding points of the original and dilated figures will be connected by straight lines, being the center of dilation the point where all the lines meet.

The only option that meets this requirement is:

A) (x, y) → (3x, 3y)

Whose scale factor is k = 3 making the dilated figure larger than the original one.
