Hello :
the equation 3x^2+4x-7=0 has 2 solutions because : ac <span>< 0
a = 3 b=4 c= -7
</span>Δ = b²-4ac....... b² ≥ 0 and -4ac > 0 ..... (ac < 0 )
coclusion : Δ>0.....(2 solutions)
The difference between the price that DeMarkus thought he should pay and the price that the store charged him is $24
The question provided is incomplete. Here is the complete question : DeMarkus says that a store overcharged him on the price of the video game he bought. He thought the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48 , what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him? A. $28.50B. $36.00C. $42.50D. $24.00
The first step is to determine the price DeMarkus thought the price of the videogame was = 1/4 of the original price
1/4 x $48 = $12
The second step is to determine the actual discounted price.
Actual discounted price = original price = (1/4 of the price)
48 - (1/4 x $48 = $12)
$48 - $12 = $36
The third step is to determine the difference in the prices
$36 - $12 = $24

If you have an app like Desmos, you can just input that. If not, you would subtract X from both sides to get 2y=-x-2. Then, you would divide by 2 on both sides to get y=-1/2x-1. You can input that into Desmos or a graphing calculator. Please mark me brainliest, but its fine if you don’t want to. Have a good day!
