164 = 5x-7(4x-7) can you guys make the steps a little bit simpler? and you < 3

164 = 5x - 7(4x - 7)      Distribute 7 into (4x - 7)

164 = 5x - (4x(7) - 7(7))

164 = 5x - (28x - 49)    Distribute - into (28x - 49)

164 = 5x - 28x + 49      Combine like terms

164 = -23x + 49         Subtract 49 on both sides

164 - 49 = -23x + 49 - 49

115 = -23x        Divide -23 on both sides

-5 = x

[you could have just distributed -7 into (4x - 7), then combine like terms, etc. But I didn't know how to write that, sorry]

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.

answer: b
