A parabola, with its vertex at (0,0), has a focus on the negative part of the y-axis.

Which statements about the parabola are true?

SELECT TWO OPTIONS

The directrix will cross through the positive part of the y-axis.
The equation of the parabola will be in the form y^2 = 4px where the value of p is negative.
The equation of the parabola will be in the form x^2 = 4py where the value of p is positive.
The equation of the parabola could be y^2 = 4x.
The equation of the parabola could be x^2 = -1/2y.

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.

hope this is what you were asking for!

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
