Let x = the smaller numberLet 3x + 15 = the larger numberx + 3x + 15 = 634x = 48x = 123(12) + 15 = 51
Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Answer:
The answer is B.
Step-by-step explanation:
You have to apply the area of triangle formula :
Answer:
x=-1/2
Step-by-step explanation:
Move -2x to the other side by adding 2x on both sides:
12x+8=2
Move 8 to the other side by subtracting 8 on both sides:
12x=-6
Divide by 12 on both sides:
x=-1/2
Hope this helps!
C. 1/5,2/5,3/5,4/5 and 1 since all will be on the same mark as 2/10,4/10,6/10,8/10 and 10/10.
d. there would be 10/10 for every 0 to 2.
