What's g(x) and f(x)?

Mathematics
1 answer:
USPshnik [31]3 years ago

The actual question doesn't ask for g(x) or f(x), only their difference k.   We count squares, say on the y axis, and get k=5, i.e. g(x)=f(x)+5.

If we really want to know the equations of each line, we see the slope is 1/3 and f and g have respective y intercepts -2 and 3.  So

f(x) = \frac 1  3 x - 2


g(x) = \frac 1 3 x +3


k = g(x)-f(x) = 5

The solution to the system of equation below is (−2, −1).
diamong [38]

Answer:

Solution is given by (-2,-1)

Step-by-step explanation:

2x-3y = -1

11x-9y = -13

Multiplying equation 1 by -3  and adding it to equation 2 ,we get

-6x+9y = 3

11x -9y = -13

___________

5x  =   -10

gives x = -2

plugging this value in equation (1) ,we get

2(-2) -3y = -1

-4 -3y =-1

 -3y =-1+4

 -3y =3

    y = -1

solution is (-2,-1)

Help me please asap!
ad-work [718]

Answer:

Step-by-step explanation:

First you must notice each of them share an x value in the exponent. So with that being said x is your GCF or in otherwords greatest common factor.

So you have an x(x^3-6x^2+9x)

you must take x from all of them inside the ( )

because x is your gcf :)

So x(x^2-6x+9) Now you use the trail and method error

to get (x-3 )(x-3 )you need two numbers that multiply to 9 but add up to -6 so... that would hmmm -3 and -3 cause -3*-3=9 and -3+-3=-6

don't forget your GCF bring it down because it's always in your answer

x(x-3)(x-3)

or..

x(x-3)^2 both are the same thing

ANSWER CAN BE

x(x-3)(x-3) OR x(x-3)^2

Both are the same thing just written different! You're welcome!

The initial value of a quantity Q (at year t = 0) is 112.8 and the quantity is decreasing by 23.4% per year. a) Write a formula
Svetach [21]

Answer:

a) Q(t) = 112.8*(0.766)^{t}

b) When t = 10, Q = 7.845.

Step-by-step explanation:

The value of a quantity after t years is given by the following formula:

Q(t) = Q_{0}(1 + r)^{t}

In which Q_{0} is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.

a) Write a formula for Q as a function of t.

The initial value of a quantity Q (at year t = 0) is 112.8.

This means that Q_{0} = 112.8.

The quantity is decreasing by 23.4% per year.

This means that r = -0.234

So

Q(t) = 112.8*(1 - 0.234)^{t}

Q(t) = 112.8*(0.766)^{t}

b) What is the value of Q when t = 10?

This is Q(10).

Q(t) = 112.8*(0.766)^{t}

Q(t) = 112.8*(0.766)^{10} = 7.845

When t = 10, Q = 7.845.
