Answer:
its on answer. come hi
Step-by-step explanation:
It would be 9. Because each person has to pay 4$ so 9*4=36 or 36/4=9
If function f(x) = 3x² + 5 then the value of f(x + 3) - [f(x) + 3] is 18x + 24.
Given the function f(x) = 3x² + 5.
We have to find the value of f(x + 3) - [f(x) + 3]
First we have to find the value of f(x + 3) - [f(x) + 3]
f(x + 3) = 3 (x + 3) ² + 5f(x + 3)
= 3(x ² + 6x + 9) + 5f(x + 3)
= 3x ² + 18x + 27 + 5f(x + 3)
= 3x ² + 18x + 32
Now substitute these values and find the value of f(x + 3) - [f(x) + 3].
f(x + 3) - [f(x) + 3] = (3x² + 18x + 32) - [3x ^ 2 + 5 + 3]
=3x ² + 18x + 32 - 3x ² - 8
=18x + 24

3y-2z=7
y=
......equation(1)
Given x+2y-6=z
x=z-2y+6
putting value of y from equation(1)
By simplifying x=
.....Equation(2)
Now putting the value of x and y in term of z in 3rd given equation
i.e 4+3x=2y-5z
i.e 2y-5z-3x=4
i.e 2()-5z-3()=4
By simplifying we will get -8z+14=24
i.e z=
Now putting z value in Equation(1);y=3/4
And putting z value in Equation(2);x=7/3 (Answer)
