<span> The quadratic formula says that any quadratic equation of the form ax^2 + bx + c, then
x=(-b ± √(b^2 - 4ac))/2a, and so because of the square root, theres
obviously going to be no x-intercepts if b^2 - 4ac is negative, one
x-intercept if its zero, or two if its positive. So to calculate the
discriminant, which is whether it has an intercept, no intercepts or two
intercepts is:
∆=b^2 - 4ac, where delta, the greek equivalent of D, is used to represent the discriminant.
In the above equation a=-4, b=3 and c=-2, so
∆=3^2 - 4*-4*-2=9 - 32=-23, so because the discriminant is negative, then there are no x-intercepts.

Answer:
8 % of 4350 is a rate of $348 / yr or $29 per month.
So 124.62 - 29 = 95.62 towards the principal for the 1st month.
That would leave a balance due of 4350 - 95.62 = 4254.38.
4254.38 * .08 = 340.35.
340.35 / 12 = 28.36 interest to be paid in the second month with
124.62 - 28.36 = 96.26 going towards payment of the principal.

Answer:
Sparkle wands: NO
Fairy wands: YES
Glass wands: NO
Step-by-step explanation:
To find the price per glitter wand, you have to divide the price of the wands by the amount of wands you have.
$50/8 = $6.25
Divide the price of the wands by the amount you get.
Sparkle wands: $20/4 = $5
Fairy wands: $37.50/6 = $6.25
Glass wands: $65/10 = $6.50
The sparkle wands and the glass wands do not have the same price per wand as glitter wands.
The fairy wands have the same price per wand as glitter wands.
Answer:
x = 13
Step-by-step explanation:
Sum or interior angles of a triangle is 180,
6x + 19 + 5x - 15 + 3x - 6 = 180
6x + 5x + 3x + 19 - 15 - 6 = 180
14x + 19 - 21 = 180
14x - 2 = 180
14x = 180 + 2
14x = 182
x = 182 / 14
x = 13
