Tak's phone can store 64 videos which are each one minute long; or
32 videos of length two minutes, or
16 videos of length four minutes; etc.
a. Find the number of videos of length 16 minutes Tak
could store on his phone.
b. Find a function to represent the relationship
between the number of videos on Tak's phone (x)
and the length of each video ( y minutes)
c. Sketch a graph of the function you found above.
d. Tak wants to store 48 videos on his phone. Find the
appropriate line on the same set of axes to find the
maximum length of each video.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
