The product of the roots of 8x^2 - 2x = 1 is:
-1/8
1/8
1/4

FIRST OPTION.

Step-by-step explanation:

You can find the roots as following:

-Make the equation equal to zero:

- Apply the quadratic formula as following:

Where:

a=8

b=-2

c=-1

Therefore, you obtain:

The product is the result of multiply both roots:

Option A. -1/8 is the correct option.

Step-by-step explanation:

We have to get the product of the roots of the given equation.

Since the equation is 8x²- 2x = 1

8x² - 2x - 1 = 0

8x² - 4x + 2x -1 = 0

4x(2x - 1) + 1(2x -1) = 0

(4x + 1)(2x - 1) = 0

Here the equation has two roots

4x +1 = 0

4x = -1

x = -1/4

and 2x - 1 = 0

2x = 1

x = 1/2

Therefore product of the given roots will be

= (-1/4)×(1/2) = -1/8

Option A. -1/8 is the answer.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
