Answer:
(-4, 7)
Step-by-step explanation:
reflecting it over the x-axis changes the x-coordinate to the opposite. reflecting it over the y-axis changes the y-coordinate to the opposite.
Answer:
10 = b
Step-by-step explanation:
Begin by expanding (x + 5)^2
(x + 5)(x + 5)
First: x*x = x^2
Outside: x * 5 (the last term which is a 5)
Inside: 5+ x
Last: 5*5 = 25
x^2 + 5x + 5x + 25
x^3 + 10x + 25
Two possibilities:
28^2 + x^2 = 96^2
OR
28^2 + 96^2 = c^2
784 + x^2 = 9216
subtract 784 from both side
x^2 = 8432
Take the square root of both sides
x = 91.83 NOT an Integer
28^2 + 96^2 = c^2
784 + 8216 = c^2
10,000 = c^2
Take the square root of both sides
c = 100 HYPOTENUSE
Yes; LNM ~ OQP because of the SAS~ postulate
