-x + 2y= -1 x= -15 value of y?

1 answer:

8 0

Simply plug in -15 for x in our given equation.

-x + 2y = -1

-(-15) + 2y = -1

Simplify.

15 + 2y = -1

Subtract 15 from both sides.

2y = -1 - 15

Simplify.

2y = -16

Divide both sides by 2

Y = -8

Hope I helped :)

-12=-2(2-8) <br> Is it true false or an open sentence

MissTica

The statement is false because when you use distributive property, you get -12=-4+16 and when you add 16 to -4, you'll get 12, not -12, making the statement false.

Next, you will make a scatterplot. Name a point that will be on your scatterplot and describe what it represents.

klio [65]

The point (12, 190) means that the temperature after 12 hours is 190 degrees Celsius

<h3>How to make a scatter plot?</h3>

To do this, we make use of the following points

(12, 190), (14, 201), (15, 301), (16, 305), (18, 350), (20, 40), (25, 450)

Where x represents the number of hours and y represents temperature

See attachment for the scatter plot.

<h3>The description of a point</h3>

Which kinds of symmetry does a square have?

spin [16.1K]

Vertical symmetry because you can cut a square in half vertically and the two parts be exactly the same. Horizontal symmetry because you can cut a square in half horizontally and the two parts be exactly the same. Diagonal symmetry because you can cut the square from corner to corner and the two parts look exactly the same. Rotational symmetry because you can rotate the square and it still look exactly the same. So a square has all of those symmetries. I hope this helped!
