How many solutions does the system have?
x + y = 5
x + y = 6
- none
- one
- two
-infinite

none

Step-by-step explanation:

to solve this equation we would say that

let

x + y = 5 equation 1

x + y = 6 equation 2

from equation 2

x + y = 6 equation 2

x = 6 -y equation 3

substitute for x into equation 1

x + y = 5 equation 1

6 - y + y = 5

from here this equation cannot be solved further therefore it has no solution.

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
