Answer

The solution for the two system of equations is (-4,2)

Explanation

Equation for slope-intercept

The equation for slope-intercept form is y = mx + b

-mx represents the slope of the equation

-b represents the y-intercept

Determine the slope and the y-intercept

The slope of the two equations can be found based on what the number in front of the x is, this term is also called the coefficient.

The y-intercept is in the form of b and is substituted normally by a positive or negative integer.

Slope: 1/4 and 2

Y-intercept: 3 and 10

You must graph these, for this problem I have provided one for you.

Determining the solution

Since this problem requires you to find the solution based on the graph you must graph the two lines and the solution is the point in which the two lines intersect.

Based on the graph I have provided for you, we can determine that the solution is (-4,2)

Checking your work

In math it's very important to check your work: plug in the solution and if it is a perfect math then the solution is correct.

The solution applies to the first equation, however we must now check for the second equation.

The solution also applies to the second equation, so we now know that this solution is correct.

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.
