Answer:
(8,-2)
Step-by-step explanation:
When reflecting something across the X axis the y axis coordinate is the one that will change to put the position further up or down. In this case we are moving it down to the same amount below the axis that it is now above it. That means that since it is currently 2 above the X axis it would then be 2 below the X axis making it at -2 so the coordinates would be (8,-2)
I hope this helps and please don't hesitate to ask if there is anything still unclear!
You want to use the addition property, so you need to ADD each term. Just change the minuses to pluses, making sure you keep the negative with the number
5x-8x-7y+y =
5x + -8x + -7y +y
Answer:
Always
Step-by-step explanation:
8 - 9 = -1
1/3 - 1/6 = 1/6 are 2 examples
( y - 4 ) ( y² + 4 y + 16 ) =
= y³ + 4 y² + 16 y - 4 y² - 16 y - 64 = y³ - 64
If the result is the polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y - 64
a = 16
Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse QR
Use Pythagoras' identity to solve for QR
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
QR² = 8² + (8
)²
= 64 + 192
= 256 ( take the square root of both sides )
QR = 
= 16
