A discount voucher offering 15% off is sued to pay a bill

mel-nik [20]

Answer:244.8

Step-by-step explanation:

15% of y=36.72

15/100 x y=36.72

15y/100=36.72

Cross multiply

15y=36.72 x100

15y=3672

Divide both sides by 15

15y/15=3672/15

y=244.8

What is the discriminant of 3 x squared minus 10 x = negative 2?

sasho [114]

Answer:

The discriminant of 3 x squared minus 10 x = negative 2 is 76

Explanation:

Given:

$3x^2-10x=-2$

$3x^2-10x+2=0$ ..........(1)

We can find out the discriminant by using the formula

$D=b^2-4ac$

So from the equation (1)

We have b = -10

a= 3

c= 2

Now put all these values of a,b and c in the formula of discriminant to find out the value of D

$D=(-10)^2-4(3)(2)$

$D=100-24=76$

D=76

So the discriminant of the given quadritic equation = 76
