Answer:
discriminant: 241
2 real roots
Step-by-step explanation:
The discriminant is the part of the quadratic equation that is under the sqare root
x=(-b±√(b²-4ac))/2a
discriminant: b²-4ac
We also know that a quadratic equation is in the form ax²+bx+c = 0, so we can plug in the values we know from our equation to find the discriminant.
a=4
b=-17
c=3
(-17)^2-4(4)(3)
We also know that if the discriminant
is positive we have 2 real roots
is 0 we have 1 real root aka a repeated real solution
is negative we have no real roots
The equation should be:
the cost of water times the number of bottles plus the cost of iced teas times the number of bottle equals 100
1.49 times number of water bottles + 1.25 time number of iced tea bottles = 100
1.49x + 1.25y = 100
The answer is B. she forgot to multiply 1,25 to the number of iced tea bottles/
