Answer:
y=-3(x-9)
Step-by-step explanation:
Point slope form is y-y1=m(x-x1)
x1=9
y1=0
m=-3
plug it all in!
y-0=-3(x-9)
y=-3(x-9)
Hope this helps!
Answer:
5. (2,4) 6. (-1,6)
Step-by-step explanation:
The solution to multiple graphs is where the two graphs meet.
(-1,6) is the only point where both of the y values are the same.
Answer:
x<5
Step-by-step explanation:
the greater sign will firstly be changed to = for better solving so we obtain
3+9x=4(x+7)by opening bracket
3+9x=4x+28
9x-4x=28-3
5x=25
divide all through by 5x
we obtain
x=5
the greater sign change here
which is x<5

Lunchbox:$9
9+9=18
24x18=$432
Answer:
Pretty sure it's C
Step-by-step explanation:
For inverse functions, I do the opposite operation
the only logical inverse function I see working in this expression would be C
divide the 5 from 5x and add the 3
Also, subtract the f(x) on both sides to get the "- y"
so, you get : 5/x + 3 = - y (f(x) is just "y")
