Sushirama sells rolls for 12$ each. for 20$ per month, you can purchase a discount card which makes the rolls 9$ each. which inequality below couod be used to find how many rolls of sushi(r) you would need to eat in month to make the discount card a good deal? (a) 12r > 20 + 9r (b) 12r > 20r + 9 (c) 12r < 20 + 9r (d) 12r < 20r + 9

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
