Answer:
B
Step-by-step explanation:
The graph of x² is known as the parent function. From it, all quadratics can be transformed to make their graphs. It can undergo a series of transformations like translations up/down/left/right or stretch and compression vertically and horizontally. Usually the equation can tell you you what transformations it undergoes. Since g(x) is the same equation as x² except for 4/5 this is a vertical compression. Since it is the leading coefficient under multiplication and 4/5 < 1, this is a compression vertically. Answer B is correct.
-2/5 +1/2w = -6/7
move the -2/5 over by addition
1/2w = -16/35
w = -32/35
Answer:
C 3/14
Step-by-step explanation:
There are a total of 8 checkers
P (black) = black/total
= 2/8 = 1/4
Then we keep the checker, so there are only 7 checkers in the bag, 6 red and 1 black
P ( red) = red/total
= 6/7
P (black, red) = 1/4 * 6/7
= 6/28 = 3/14
