8. Country Carpets charges $22 per square yard for carpeting, and an
additional installation fee of $100. City Carpets charges $25 per square
yard for the same carpeting, and an additional installation fee of $70.
a. Write and solve an equation to find the number of square yards of
carpeting for which the total cost charged by the two companies
will be the same.

the perimeter is increased by a factor of 2

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

the ordered pairs for the given function are of the form
