Translation (x,y) ⇒ (x-2, y-16) means the triangle PQR is translated two units to the left and sixteen units down.
Each x-vertices will move two units left and y-vertices will move 16 units down
P(-2, 6) ⇒ (-2-2, 6-16) ⇒ (-4, -10)
Hence y-coordinate of the image of P is -10
(From top to bottom) wrong, right, right, right, wrong. This is because a irrational*an irrational number is rational, but a rational*an irrational is an irrational number
(Hard to put it in words for me so here is a picture)
Or you can use point-slope form (
) and insert the slope of -2 and the point (3,6) like this:
And simplify if needed.
Have a great day!
Answer: You basically have to 2xlw+2wh+2lh which means
2 multiplied by the length and width + 2 x the width and the height+ 2 x the length and height
Example:
l= 2
w=5
h=4
2x2x5+2x5x4+2x2x4
I hope this helps
Answer:
2x³ - 2
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
= x(2x² + 2x + 2) - 1(2x² + 2x + 2) ← distribute both parenthesis
= 2x³ + 2x² + 2x - 2x² - 2x - 2 ← collect like terms
= 2x³ - 2
