Hello!

You put in the know values for x or y
------------------------------------------------------------------------------------------------------
(-6, ?)

We know that x is -6

6y + 5(-6) = -30

Combine like terms

6y + -30 = -30

Add 30 to both sides

6y = 0

y = 0
------------------------------------------------------------------------------------------------------
(?, 5)

We know that y is 5

6(5) + 5x = -30

Combine like terms

30 + 5x = -30

Subtract 30 from both sides

5x = -60

Divide both sides by 5

x = -12
------------------------------------------------------------------------------------------------------

The answers are (-6, 0) and (-12, 5)

Hope this helps!

If you flipped the graph of y = x2 + 2x - 2 vertically, you would get the graph of y = -(x2 + 2x - 2). true or false

Hi friend,
If you flipped the graph y=x^2+2x-2 vertically, you would get the graph y=-(x^2+2x-2) TRUE. 
Hope this helps you!

Write an equation in which the quadratic expression 2x^2-2x-13 equals 0
torisob [31]

Answer:

x = 3 and -2 are the two solutions.

Step-by-step explanation:

2x^2 -2x -12 = 0

First factor out a 2

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0

2 = 0 x - 3 = 0 x + 2 = 0

2 does not equal zero so this is an extraneous solution

x - 3 = 0 so x = 3

x + 2 = 0 so x = -2

The solution is n=-2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?
77julia77 [94]

Answer:

- 0.8 = - 0.8

n = - 2 is a solution.

Step-by-step explanation:

1.4n + 2 = 2n + 3.2

1.4(- 2) + 2 = 2(- 2) + 3.2

- 2.8 + 2 = - 4 + 3.2

- 0.8 = - 0.8

How to solve

1.4n + 2 = 2n + 3.2

1.4n + 2 - 2 = 2n + 3.2 - 2

1.4n = 2n + 1.2

1.4n - 2n = 2n - 2n + 1.2

- 0.6n = 1.2

- 0.6n ÷ - 0.6 = 1.2 ÷ - 0.6

n = - 2

maks197457 [2]

Answer:

(1.7x10^13)+(0.8x10^13)

=(1.7x1e+13)+(0.8x1e+13)

=1.7e+13+0.8e+13

=2.5e+13

in actual number it would be 25,000,000,000,000

Translate the shape A three squares right and one square down.What are the coordinates of the vertices of the image?
nataly862011 [7]

If the shape A is translated four squares right and two squares up, the resulting coordinate point will be at (-2, 5), (-2, 2) and (0, 2)

<h3>Translation of coordinates</h3>

Translation is a transformation technique of changing the position of an object on the xy plane

Given the coordinates of the vertices (1, 4), (1, 1), (3,1)

If the shape A is translated three squares right and one squares up, the resulting coordinate point will be at (-2, 5), (-2, 2) and (0, 2)

Note that 4 was subtracted from the x-axis and 2 added to the y-coordinates.
