Answer: (4,4)
Step-by-step explanation:
(1,-4) reflected over the x-axis is (1,4). Then translated 3 units up is (4,4). Hope this helps
-2(5,6)-40 I think that's it
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
6x+8=100
6x=92
X= 15.33 or x =15 1/3
40 is an acute angle.
30 is an acute angel.
110 is an obtuse angle.
The easiest way to remember is anything below 90° (which is a right angle) is acute (think, cute = small). Anything above 180° is obtuse.
