</span><span>6x - 4x + 4 = 14
</span><span>
</span><span>2x + 4 = 14  | - 4
</span><span>
</span><span>2x + 4 - 4 = 14 - 4
</span><span> 
</span><span>2x = 10   | :2

The point M(-6, -4) is translated 2 units right. What are the coordinates of the resulting point, M′?
fredd [130]
B) (-4, -4)

When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.

Remember: (-6, -4)
X = -6
Y = -4

If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)

Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

81 {x}^{2}  - 324 {y}^{2}  \\  \\  =  {(9x)}^{2}  -  {(18y)}^{2}  \\  \\  = (9x + 18y)(9x - 18y) \\  \\  = 9(x + 2y) \times 9(x - 2y) \\  \\  = 81(x + 2y)(x - 2y)

2.375 in expanded form
kari74 [83]

Answer:

2375^-3

Step-by-step explanation:

Move the decimal place from 2.375 to the back of the number so it should look like this, 2375.

Than move the decimal place back to its original spot and count the amount of spaces you move. Remember, if you move forward, your exponent should be negative. For example, if the problem is 6.321, you would move the decimal place to the back like this, 6321. And then move it back to where it originally was, 6.321, the amount of spaces I moved was 3 spaces and I moved forward so It would be 6.321^-3
