1. Robert and Erica, were reviewing equations of parabolas for their upcoming math test. They disagreed on what the equation would look like for a parabola
whose vertex was at (-5.4)
a. Help them write an equation for a parabola that opens upward from its
vertex (-5,4). What is the equation of its line of symmetry?
b. Robert wants the same parabola to open down and Erica wants it to be
compressed. Show them how to change your original equation to meet
both of their desires. Does the line of symmetry change?
c. Move your parabola from part (b) 8 units to the left and 7 units up and
stretch it vertically so that it is thinner than the original
parabola. What is the equation of the parabola? What is the equation
of its line of symmetry?

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.

step-by-step explanation:

answer: youre the sweetest thing for that

if you get paid hourly because if you get a salary you could work all week and only get paid a certain amount no matter how much you work but if you get paid hourly then you get paid for every minute you worked.
