The number of DVDs sold at a store in a month was 930 and the number of DVDs sold decreased by 12 per month. The number of Blu-ray discs sold in the same store in the same month was 512 and the number of
Blu-ray discs sold increased by 26 per month Let d represent the number of discs sold and represent the
d-930 - 127
The system of equations
d=512 +267
can be used to represent this situation
time in months
If this trend continues, how many months will the number of DV's sold equal the number of Blu-ray discs
sold? How many of each is sold in that month?
There will be
DVDs and Blu-Ray discs sold per month in
months.

i dony know

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
