Rohan bought a new memory card for his digital camera. If he takes only hi-res photos, he can store 3,500 pictures. If he takes only lo-res photos, he can store
7,000 photos
(a) Write a linear equation to represent all the combinations of numbers of
hi-res (x) and lo-res (y) photos Rohan can store on his memory card.

it should be a.

hope it

answer: $1794

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
