Answer: The y values remain the same, but the x value changes its sign
Step-by-step explanation: There is a way to remember this. If you reflect across the y axis the y will stay the same and, if you reflect across the x axis the x will stay the same. So if the axis is in the problem then that axis will stay the same and the other axis will change to its opposite.
Answer:
vertical angles are equal:
< (1) = < (2) (in fact they are congruent angles)
so, if measure of < 1 is 63° and measure of < 2 is 4x-9°, than
4x-9=63° ...solve for x
4x=63%2B9°
4x=72°
x=72%2F4°
x=18°
if x=18°, than < 2 is 4x-9=4%2A18-9=72-9=63°...it proves that < (1) = < (2) are congruent angles

Answer:
3360
Step-by-step explanation:
simple interest=principle*rate*time/100
simple interest=20000*5.6*3/100
simple interest= 200*5.6*3
simple interest = 3360
Step-by-step explanation:
f(x) = x√(x+8)
When f(x) = 0,
0 = x√(x+8)
x = 0, x + 8 = 0
x = -8
f'(x) = (1)√(x+8) + x • ½(x+8)^(-½) = 0
0 = √(x+8) + 1/[2√(x+8)] (x)
-2(x+8) = x
-2x - 16 = x
x = -16/3
(-8 < -16/3 < 0)
Therefore, x-intercept of f'(x) = 0 is somewhere between the two x-intercepts, ranging from -8 to 0.
