Which of the following values for c would mean that the system of equations 2x – 3y = 1 and cx – 3y = 2 will have a solution of (–1, –1)?
a.2
b.3
c.1
d.0

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

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.
