juan and adam both need pens and batteries. The equation that represents Juan's purchases is y= 27 -3x. The equation that represents Adam's purchases is y = 17 - x. if x represents the price of the batteries, and y represents the price of the pens, what are the price of the pens snd batteries. Please if you answer this explain it!

pens are 12

batteries are 5

Step-by-step explanation:

y=27-3x          y=17-x

-17 +3x 27-3x=17-x -17 +3x

2x=10

x=5

y=27-3x     y=27-3(5)     y=27-15  

y=12

pens are 12

batteries are 5

Step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
