The inverse function is f(x) =
You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.
f(x) = 2x + 1 ---> Switch the f(x) and x values
x = 2f(x) + 1 ---> Subtract 1 from both sides
x - 1 = 2f(x) ----> Divide each side by 2.
= f(x) ---> Switch the order so that it looks like a function.
f(x) =
And that would be your inverse function.
Answer:
x=12
Step-by-step explanation:
The two angles make a straight line, which is 180 degrees
10x-20 +6x+8 = 180
Combine like terms
16x -12 = 180
Add 12 to each side
16x-12+12 = 180+12
16x =192
Divide by 16
16x/16 = 192/16
x =12
The group represents equivalent ratios.
Answer: Option B
<u>Step-by-step explanation:</u>
As we see carefully, the equation B represents the equivalent ratio. Because if you divide the 7 by 10 then you will get 0.7 and this 0.7 can also be written as 70% in percentage form. So, the correct answer is Option B.
Case A:
It can be written as that 0.75, 0.5, 0.8.this group does not represent equivalent ratios
Case B:
If you divide the 7 by 10 then you will get 0.7 and this 0.7 can also be written as 70% in percentage form. This group represents equivalent ratios
Case C:
It can writes as that 0.7,0.7.0.25 so this group does not represent equivalent ratios
Case D:
This gives 0.7, 0.14, 0.7 so this group does not represent equivalent ratios.
• is eg. 5 is 10/2
• same as eg. 5 is the same as 10/2
• equivelant to eg. 5 is equivelant to 10/2
