Answer:

Step-by-step explanation:

The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.

Any linear function is of the form y=mx+b

Here m is slope and b is y intercept.

Slope is difference in y divided by different in x values .

In the question for 5 persons cost is $100 and for 10 persons cost is $162.50

So the points are (5,100) and (10,162.50)

Slope m=\frac{162.50-100}{10-5}=12.50

We can find the value of b by taking m=12.50 and (x,y)=(5,100)

Substitute these values in y=mx+b

100=12.50(5)+b

100=62.50+b

Subtracting 62.50 both sides

b=100-62.50

b=37.5

a) Put m=12.50 and b=37.50 to get the equation

y=12.50x+37.50

b)Rate of change is the m value or the slope of the function.

Initial value that is (5,100) gives us one of the points to find the rate of change.

Plss I need this quickly I don't understand this<br>3(x-6)=6+7​
Rufina [12.5K]

Answer:

x = \frac{31}{3}

Step-by-step explanation:

Given

3(x - 6) = 6 + 7, that is

3(x - 6) = 13 ← distribute parenthesis on the left side by 3

3x - 18 = 13 ( add 18 to both sides )

3x = 31 ( divide both sides by 3 )

x = \frac{31}{3}

DiKsa [7]

Question 1:

Multiply the regular price by the number of people (x)

Y = 25x

Question 2:

Multiply the special rate by number of people(x) and add the cost of the room:

Y = 15x + 150

Question 3:

Replace x with a positive value and solve for y, which will be larger than the x value

Answer (15,375)

Question 4:

This means for 15 people the total cost for the special rate would be $375
