Heather is solving an equation by graphing the expressions on both sides. if her graph intersects at an infinite number of points, which statement could describe the equation heather is attempting to solve?
a. one side of the equation is a constant, and the other side of the equation is a linear expression.
b. one side of the equation is a linear expression, and the other side of the equation is a quadratic expression.
c. one side of the equation is a constant, and the other side of the equation is a quadratic expression.
d. one side of the equation is a quadratic expression, and the other side of the equation is a quadratic expression.

D. One side of the equation is a quadratic expression, and the other side of the equation is a quadratic expression.

Step-by-step explanation:

Knowing that she got an infinite number of points in the resolution, indicate us that both sides of the equation have a similar expression, that is, both are linear,  both are quadratic, et cetera. Because, in this case, the two terms overlap each other giving infinite solutions. In any other case, for example, one term is constant and the other is quadratic, the solution (if exist) gives finite points. In the example that could be one or two points, depending on the specific case.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

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.
