Answer:
15 friends
Step-by-step explanation:
37 - 7=30 so then you divide 30 by 2 which equals 15 so there is your answer.
Answer:
B)y = 3x^2 - 3x-18
Step-by-step explanation:
y = (3x – 9)(x + 2)
y = 3x*x+3x*2-9*x-9*2
y = 3x^2 +6x-9x-18
y = 3x^2 - 3x-18
Answer: B
Step-by-step explanation: The answer would be B because you would add n the number and 6 then you would multiply it by 2
The inverse function is equal to f-1(x) = (x - 1)/3 and the value at f-1(6) is equal to 5/3.
To find the inverse, you need to switch the f(x) and x in the equation. Then you can solve for the new f(x). The result will be the inverse (f-1)
f(x) = 3x + 1 ----> Switch f(x) and x
x = 3f(x) + 1 ----> Subtract 1
x - 1 = 3f(x) ----> Divide by 3.
f-1(x) = (x - 1)/3
Now that we have the inverse, we can plug 6 in to get the value at f-1(6).
f-1(x) = (x - 1)/3
f-1(6) = (6 - 1)/3
f-1(6) = 5/3
Answer:
No, he will not be able to buy it.
