Answer:
y = -2x + 8
Step-by-step explanation:
y = mx + b
-8 = -2(8) + b
-8 = -16 + b
8 = b
y = -2x + 8
Answer: -12
Step-by-step explanation: because -7- 5= -12
Answer:
Step-by-step explanation:
The inverse function can be found by solving ...
f(y) = x
(√y)/5 +2 = x
(√y)/5 = x -2 . . . . . subtract 2
√y = 5(x -2) . . . . . . multiply by 5
y = 25(x -2)² . . . . . square both sides
The inverse function is ...
_____
<em>About the graph</em>
The inverse of a function is its mirror image across the line y = x.
Answer:
12
Step-by-step explanation:
For the top triangle, he has 3 options
3C1 = 3
For the middle one, he can't use the top triangle's colour, so 2 options
2C1 = 2
For the ones on sides of the middle one, 2 options each
2C1 × 2C1 = 4
3 × 2 × 2 × 2 = 24
These include all three outer ones same, so subtract 3
Also, these include 2 of the three outer ones same, so subtract:
3C2 × 3 = 9
24 - 3 - 9 = 12
