Astore owner buys leather for his handmade shoes at a wholesale warehouse. he finds that when he sells each pair of
shoes for $75, the average number of customers per week is 30 people. later, he finds that for each $5 decrease in the
price per pair of shoes, the number of customers increases by an average of 5 people per week.
the weekly revenue from his sales is given by the polynomial below, where x is the number of $5 decreases in the price
per pair of shoes over $75.
r = 2,250 + 2251 - 25.12
use the information given above to determine how to best complete the following sentences.

the binomial (30 + 5x) is a factor of polynomial r(x). does this binomial represent revenue, number of customers, or
price per pair of shoes? does this binomial take into account the price decreases?
the binomial represents the average

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
