Answer:
i'm guessing you're asking which expression is the same as 7(x+4)
i don't know what the other numbers listed are suppose to mean, but when expanded, 7(x+4)=7x+28
anything added together, multiplied together, etc, that equals 7x+28 is your answer
Answer:
The inverse of the function is (3x+4)/2
Step-by-step explanation:
To find the inverse, exchange x and y and then solve for y
y = (2x-4) /3
Exchange x and y
x = (2y-4)/3
Solve for y
Multiply each side by 3
3x = (2y-4)/3 *3
3x =2y-4
Ad 4 to each side
3x+4 = 2y-4+4
(3x+4) =2y
Divide each side by 2
(3x+4)/2 =2y/2
(3x+4)/2 = y
The inverse of the function is (3x+4)/2
I guess this is what you mean 3√a^10 and 3√b^7
Answer: 120
Step-by-step explanation:
There are 5 digits that are odd, 1 3 5 7 9
There are 5 possibilities for the first digit, 4 for the second, 3 for the third, and 2 for the last, so there are 5 x 4 x 3 x 2 = 120
Answer:
x = -1
Step-by-step explanation:
Start with adding 2 to -7
-7 + 2
=-5
Then divide by 5
-5/5
=-1
