Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
One of the angles of a triangle measures d°, another measures (3d)°, and the third measures (5d + 54)°. The equation becomes
d + 3d + 5d + 54 = 180
9d + 54 = 180
9d = 180 - 54
9d = 126
d = 126/9
d = 14
First angle is 14 degrees
Second angle is 3 × 14 = 42 degrees
Third angle is 5 × 14 + 54 = 124 degrees
100/10=10
Michelle used 10 dimes because a dime is worth 10 cents, a dollar is 100 cents, 10 dimes is equal to 100 cents.
It is neither.
To be even, f(x) must equal f(-x).
If you substitute -x for x, you'd get
y = (-x)^2 - 2(-x) -8
y = x^2 +2x -8
This is not the same as the original, so this is not even.
To be odd, f(x) must equal -f(-x).
If you take the -x substitution from the last step and then multiply it by -1, you'd have:
y = -1 (x^2 +2x -8)
y = -x^2 -2x +8
This is not the same as the original either.
The function is neither even nor odd.
