Answer:

Step-by-step explanation:

The function written symbolically is

f(x) = y = √(4x + 12)

Domain: Since 4x + 12 must be ≥ 0, x must be ≥ -3. [0, -3)

Range: The square root function may be zero or greater: [0, infinity)

Answer:

y-10=2/3(x-8)

Step-by-step explanation:

(y2-y1)/(x2-x1) is the equation for slope so put your points in you get 2/3 once simplified then its just a matter of putting points in the equation y-y1= m(x-x1)

Answer:

It’s the third one

Step-by-step explanation:

-1.1x+6.4>-1.3

-1.1x>-1.3-6.4

-1.1x>-7.7 multiplied by -1 gives 1.1x<7.7

Divided by 1.1 you get x<7

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.

34kurt

Answer:

Infinitely many solutions

Step-by-step explanation:

First, let's organize the equations of the lines into slope-intercept form.

x + 4y = 1
=> 4y = -x + 1
=> y = -x/4 + 1/4

And,

2x + 8y = 2
=> 8y = -2x + 2
=> y = -2x/8 + 2/8
=> y = -x/4 + 1/4

Since both the graphs are the same, the two equations have infinitely many solutions.

Will mark Brainlest!! <br>Help Please!<br>(1). find the domain and range of the following <br>

miss Akunina [59]

Answer:

Step-by-step explanation:

You have the domain. It is given as -1≤x≤1

Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.

Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0

I've included a graph so you can see how this all works.

So the range = 1 ≤ y ≤ 3
