Answer:
D. 5/6
Step-by-step explanation:
There are 30 marbles
If you add the black, red, and green marbles together, you get 25
25/30 is equivalent to 5/6
-16w-26+9w=-61
-16w+9w=-61+26
-7w=-35
w=5
Answer:
y = cos(x) -1
Step-by-step explanation:
The function has a maximum at x=0, a peak-to-peak amplitude of 2, and a period of 2π. It matches a cosine function that has been shifted down 1 unit.
y = cos(x) -1
Instead of finding a number multiplied by itself twice, you look for a number multiplied by itself three times. For example, 4 is the square root of 16 because 4*4=16. 4 is the cube root of 64 because 4*4*4=64
Answer:
see explanation and attachment
Step-by-step explanation:
(1) y = -x + 2
so slope is -1 and y-intercept is (0,2)
(2) 2x - y = 7
y = 2x - 7
so slope is 2 and y-intercept is (0,-7)
