A.)Which two points should you use to find the equation of the model? Explain.

ikadub [295]

Part a)

we know that

to find the equation of the line, I will use the two points that are closest to the line

Let

A(1,14)

B(7,7)

Part b)

Find the slope

we know that

the formula to find the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute

$m=(7-14)/(7-1)$

$m=(-7)/(6)$

$m=-7/6=-1.167$

the answer part b) is

the slope is $m=-7/6=-1.167$

Part c)

we know that

the equation of the line in point slope form is equal to

$y-y1=m(x-x1)$

use the point B (7,7)

$y-7=(-7/6)*(x-7)$

therefore

the answer part c) is

$y-7=(-7/6)*(x-7)$

Part d)

we know that

the equation of the line in slope-intercept for is equal to

$y=mx+b$

we have

$y-7=(-7/6)*(x-7)$

$y=(-7/6)x+(49/6)+7$

$y=(-7/6)x+(91/6)$

therefore

the answer Part d) is

$y=(-7/6)x+(91/6)$ or $y=-1.167x+15.167$

Roderick works for JB Spas. He is installing a circular spa that will be enclosed by a square deck. The radius of the spa is 3.2

MariettaO [177]

The first thing we must do for this case is to find the diameter of the circle.
We have then:
d = 2 * r
Where,
r: radius
Substituting:
d = 2 * (3.25)
d = 6.5 feet
We now look for the perimeter of the square.
P = 4L
Where,
L: square side
L = d = 6.5 feet ("a circular spa that will be enclosed by a square deck")
Substituting we have:
P = 4 * (6.5)
P = 26 feet
Answer:
The perimeter of the deck, in feet is:
P = 26 feet

A school sold tickets to a musical.

kicyunya [14]

m=6.50t

6.50 per ticket so you multiply 6.50 by t. The money collected is the answer to the equation. Hope this helps!
