I'm assuming there is supposed to be a x next to the -9. If that is the case, the inverse is:
f(x) = (x - 8)/-9
You can find this by switching the x and f(x) values and then solving for the new f(x) value.
<span>x=-9f(x)+8 ---> subtract 8 from both sides
</span>x - 8 = 9f(x) ----> divide both by -9
(x - 8)/-9 = f(x)
Answer:
p= 42,00 divided by 2.50
Step-by-step explanation:
To only make 1/3 of the recipe you would divide all ingredients by 3 or multiply by 1/3, same thing.
Convert 2 1/4 to single fraction first
9/4 * 1/3 = 9/12 = 3/4 cup sugar
inaccurate
3 less than would be x-3, but 3-x would be 3 more
Y=2x-6 (4, 3)
(X, Y)
3=2(4)+b
3=8+b
-5=b
Y=2x-5
