Simply substitute x by its value:

1) 
f(x) = x + 4 ; x = 3p                    f(x) = x + 4 ; 
f(3p) = 3p + 4                            f(1) = 1 + 4
                                                 f(1) = 5
x = 3p                                        (1,5)
y = 3p + 4

2) g(x) = 3(x-2)                           g(x) = 3(x-2)
    g(x) = 6                                  g(1) = 3(1-2)
                                                  g(1) = 3 - 6
6 = 3x - 6                                   g(1) = -3
6+6 = 3x                                       (1,-3)
12 = 3x
x = 4
g(4) = 3(4-2)
g(4) = 12 - 6
g(4) = 6

x = 4
y = 6

For all real numbers  x  and  y, if  x # y = x(x-y), then x # (x # y) =
kati45 [8]
x\#y=x(x-y)\\\\x\#(x\#y)\\\\x\#y=x(x-y)=x^2-xy\\\\x\#(x\#y)=x\#(x^2-xy)=x[x-(x^2-xy)]=x(x-x^2+xy)\\\\=x^2-x^3+x^2y


x^2-x^3+x^2y=8\\\\x^2(1-x+y)=8\\\\x^2(1-x+y)=2^2\cdot4\iff x^2=2^2\ and\ 1-x+y=4\\\\x=2\ and\ y=4-1+x\\\\x=2\ and\ y=3+2\\\\x=2\ and\ y=5

givi [52]

Given :

Brianna is a waitress in an upscale restaurant. On Friday she waited on 12 groups of customers who spent an average of $186 per group.

Her tips averaged 18% of the total amount spent by all the groups of customers that day.

To Find :

Brianna's tip income earnings on Friday.

Solution :

Total amount of money spent by 12 groups :

P = $ 12×186 = $2232 .

She got tip of 18% of the total amount spent by all the groups of customers.

T = P\times \dfrac{20}{100}\\\\T= 2232\times \dfrac{20}{100}\\\\T=\$446.4

Brianna's tip income earnings on Friday is $446.4 .

Hence, this is the required solution.

Write the equation that describes the following variation. Don't forget "k"!
rosijanka [135]

Answer:

x=(k√x)/(w^2)(cube√z)

x varies directly with square root of y is:

x = k √y

And inversely with the square of w and cube root of s is:

/(w^2)(cube√z)

Now put those together:

x=(k√x)/(w^2)(cube√z)

The formula is:

x=ky/wz but add the specific info like square, roots, or etc
