Could someone please help me out? What is the number of real solutions? Use the dicriminant.

-11x^2 + 3x = -8

2.

Step-by-step explanation:

-11x^2 + 3x = -8

-11x^2 + 3x + 8 =0

Discriminant = b^2 = 4ac

=3^2 - 4*-11*8

= 9 + 352

= 361

The discriminant is positive so there are 2 real roots.

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
