I DON'T UNDERSTAND MATH ANYMORE!!!!!!!!
Answer:
The inverse function of 3x - 4 is (x+4)/3. so a
Step-by-step explanation:
f(x) = 3x - 4
y = 3x - 4 replace f(x) with y
x = 3y - 4 replace x with y and y with x.
3y = x + 4 solve for y
y = (x+4)/3 replace y with f-1(x)
f-1(x) = (x+4)/3
Answer:
I think you have to muitly the number by the powers frist the subtract add add subtract
Step-by-step explanation:
Multiply the values of a and c together;
9*30= 270 <— find prime factors of this
270= 3*3*3*5*2
Now find a way to add these factors in different ways to give 33 (b value)
We can try (3*3*2)+(3*5)=?
18+15=33
Now that you know the numbers, break down the b value.
9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer
Hope I helped :)
How big containers? If the four containers each hold one liter of water, than it would be four liters of water in all.
