The number of states that joined the united states between 1776 and 1849 is twice the number of states that joined between 1850 and 1900. if 30 states joined the united states between 1776and 1849 and x states joined between 1850 and 1900, which of the following equations is true?
a. 30x = 2
b. 2x = 30
c. x/2 = 30
d. x + 30 = 2

b. 2x = 30

Step-by-step explanation:

Given : 30 states joined the United States between 1776 and 1849

and x states joined between 1850 and 1900 .

If the number of states that joined the United States between 1776 and 1849 is twice the number of states that joined between 1850 and 1900.

i.e. No. of states joined the United States between 1776 and 1849= 2 (No. of states that joined between 1850 and 1900)

i.e . 30=  2(x)          [Substitute the values]

i.e . 2x=30

Hence, the true equation : 2x=30

i think is g(1)=-1.

hope that i can

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
