Consider the linear system of equations y = 2/5x - 1 and 2x -3y + 1 = 0

The solution is the point (-5,-3)

Step-by-step explanation:

The complete question is

Consider the linear system of equations y = 2/5x - 1 and 2x -3y + 1 = 0

The solution of the system of equations is?

we have

----> equation A

----> equation B

Solve by substitution

substitute the equation A in equation B

solve for x

Multiply by 5 both sides to remove the fraction

subtract 20 both sides

divide by 4 both sides

Find the value of y

The solution is the point (-5,-3)

understand that i don't know the answers

will someone answer his question

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.
