Answer:

Step-by-step explanation:
Hi there!
Slope-intercept form:
where
is the slope and
is the y-intercept (the value of y when x is 0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two given points are
and 
Plug in the given points (15,2.2) and (5,1.6):

Therefore, the slope of the line is
. Plug this into
:

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

Plug in a given point and solve for b:

Therefore, the y-intercept is
. Plug this back into
:

Answer:
Part A
C = $.85p
For 2 pounds , the charge is $1.70
Part B
C = $.05 * p
Step-by-step explanation:
Part A
Cost = charge per pound * pounds
We know the charge per pound is $.85
C = $.85 * p
We want to ship 2 pounds
C = .85*2
C = 1.70
Part B
Cost = charge per pound * pounds
We know the charge per pound is now $.05
C = $.05 * p
Answer:
x=-6
Step-by-step explanation:
use distributive property on the () and times x and 1 by three
then you subtract 6 from both sides
then subtract three from both sides
then divide both sides by 3
your work would look like this:
3(x+1)+6=-9
3x+3+6=-9
3x+3=-15
3x=-18
x=-6

Answer:
h = 1000 / (3.14)(r²)
Step-by-step explanation:
Given in the question,
volume of cylinder = 1000 inches³
Formula to use
V = πr²h
where V = volume
π = 3.14
r = radius
h = height
1000 = (3.14)(r²)(h)
h = 1000 / (3.14)(r²)
Answer:
14km
Explanation
11km + 11km = 22km is the sum of both the width.
If you want to find the length than minus the perimeter with 22.
50km - 22km = 28km is the sum of both the length.
To know only one side of the length, divide it by 2.
28km/2 = 14km is the length
