4(9x + 7) = x - 4<br><br> ALGEBRA 1!!
tiny-mole [99]

Hey!

-----------------------------------------------

Solution:

4(9x + 7) = x - 4

36x + 28 = x - 4

36x + 28 + 28 = x - 4 + 28

36x = x + (-32)

36x - x = x - (-24) - x

35x = -32

35x/35 = -32/35

x = -32/35

-----------------------------------------------

Answer:

x = -32/35

-----------------------------------------------

Hope This Helped! Good Luck!

A. Explain why the point (100,2) is on the graph.
Crazy boy [7]

Answer:

the log function is the "inverse" function of an exponential function

by definition  log_{a} b = c  then a^{c} = b

in this problem you have log_{10}  100

thus what x solves this ?  10^{x}  = 100  the answer is 10^{2}

thus (100,2)

B) the x intercept is when y = 0

   10^{0} = 1

   x intercept at (1,0)

C) at 100, the curve will hit y = 5000

Answer:

-1/36

Step-by-step explanation:

-5/18  - ( -1/4)

Subtracting a negative is like adding

-5/18 + 1/4

Getting a common denominator of 36

-5/18 *2/2 + 1/4 *9/9

-10/36 + 9/36

-1/36
