How many solutions does the system
Y=-2x+2
Y=x2-2x+4

Your expression have just one solution because a lineal equation can have only one solution, but for example, a cuadratic equation can have 2 solutions or one repeated solution

brainliest please :)

First, we calculate the total amount of the already taxed gasoline, which works out to be: 12 * 2.89 = $34.68 Next, we calculate the before tax cost of all of the other goods: 2 * 1.59 + 0.89 + 2 * 1.39 = $6.85 After inclusion of tax, this amount becomes: 6.85 x 1.075 = $7.36 The total amount Leon should have paid is: 34.68 + 7.36 = $42.04 Leon paid: 44.64 - 42.04 = $2.60 extra Therefore, the answer is C.
