Answer: 149 cartridges will be sold at 20 dollars per cartridge.
Step-by-step explanation:
Given: The projected sales volume of a video game cartridge is given by the function 
, where <em>s</em> is the number of cartridges sold, in thousands; <em>p</em> is the price per cartridge, in dollars; and <em>a</em> is a constant.
Put s(p)=100000, p= 10, we get
i.e. 
Put p=20, we get
Hence, 149 cartridges will be sold at 20 dollars per cartridge.
Answer:
<h2>y=7x+10</h2>
Step-by-step explanation:
Step one:
Base fee Charge= $10
Charges per hour= $7
Let the number of hours be x
and let the total charges be y
Step two:
the linear function for the total charges can be represented using the equation of a straight line, which is
y=mx+c
where y= tota charges
m= the charges per hour
x= is the number of hours worked
c= the base fee
Step three:
the equation is
y=7x+10
Answer:
Step-by-step explanation:
A cone is a three-dimensional closed figure that has a circular base connected to a vertex (or apex) point outside the plane of the base. Similar Cross Sections. (parallel to base) • The one and only base of the cone is a circle (or other curved figure).
1) The equation of the parallel line in Slope Intercept Form is; y = -x - 1
2) The equation of the perpendicular line in Slope Intercept Form is;
y = ³/₂x - 4
<h3>How to write equation in Slope Intercept Form?</h3>
1) When two lines are parallel, it means their slopes are the same.
Formula for equation in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Thus, slope of y = -x + 1 is m = -1.
Equation of parallel line is;
(y - (-5))/(x - 4) = -1
y + 5 = -x + 4
y = -x - 1
2) When two lines are perpendicular, it means their slopes are the negative inverse of each other. Thus;
Slope of line = -2/3 and so slope of perpendicular line = 3/2. Thus, equation of new line is;
(y + 1)/(x - 2) = 3/2
2y + 2 = 3x - 6
2y = 3x - 8
y = ³/₂x - 4

A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one.
Proof:Suppose 1 box is bought of each (x=1),Original will cost $10 & the Cheaper Price is $7
B) Each time he buys a cheap brand he save $3 ($10-$7).
On 5 cheap boxes, He would save $3 x 5 boxes = $15.
