Answer:

\large\boxed{\text{The domain:}\ x\geq-3\to x\in[-3,\ \infty)}\\\boxed{\text{The range:}\ y\geq-1\to y\in[-1,\ \infty)}

Step-by-step explanation:

y=\sqrt{x+3}-1\\\\The\ domain:\\\\x+3\geq0\qquad\text{subtract 3 from both sides}\\\\x\geq-3\to x\in[-3,\ \infty)\\\\The\ range:\\\\\sqrt{x+3}\geq0\qquad\text{subtract 1 from both sides}\\\\\sqrt{x+3}-1\geq-1\\\\y\geq-1\to y\in[-1,\ \infty)

A company offers premium cable for 39.95 per month plus a one time setup fee. the total cost for setup and 6 monthes of service
Yakvenalex [24]

Answer:

Part a) The equation of the line in point slope form is

y-264.70=39.95(x-6)

Part b) The equation in slope intercept form is

y=39.95x+25

Part c) The setup fee is $25

Step-by-step explanation:

Part a) write an equation in point slope form

Let

x ------> the number of months of service

y -----> the total cost

we know that

The equation of the line in point slope form is

y-y1=m(x-x1)

where

m is the slope

(x1,y1) is a point that lie on the line

In this problem we have that the cost of $39.95 per month is equal to the rate or slope of the linear equation

m=39.95\ \frac{\$}{month}

we have that the point (6,264.70) is a solution of the linear equation

substitute the given values

y-264.70=39.95(x-6) ----> equation in point slope form

Part b) write the equation in slope intercept form

The equation of the line on slope intercept form is

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

we have

y-264.70=39.95(x-6)

Isolate the variable y

Distribute right side

y-264.70=39.95x-239.70

Adds 264.70 both sides

y=39.95x-239.70+264.70

y=39.95x+25

Part c) what is the setup fee?​

The setup fee is the y-intercept of the linear equation

The y-intercept is the value of y when the value of x is equal to zero

In this problem, the y-intercept is the total cost when the number of months of service is equal to zero (the cost is equal to the setup fee)

For x=0

y=39.95(0)+25

y=\$25

The setup fee is $25
