Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.

Please help
Harman [31]

Answer:

we get \mathbf{gf(2)=-\frac{1}{3}}

Step-by-step explanation:

We are given:

f(x)=1-2x\\g(x)= \frac{1}{x}\\h(x)=x^3+1

We need to find value of gf(2)

gf(2)=g(f(2))

First putting f(x) inside of g(x) and then putting x=2

gf(x)=g(f(x))\\gf(x)=\frac{1}{1-2x}

Now putting x=2 to find gf(2)

gf(x)=\frac{1}{1-2x}\\gf(2)=\frac{1}{1-2(2)}\\gf(2)=\frac{1}{1-4}\\gf(2)=\frac{1}{-3}\\gf(2)=-\frac{1}{3}

So, we get \mathbf{gf(2)=-\frac{1}{3}}

At the family reunion there were 15 more family members there this year than at the last family reunion. There were 46 people at
Kipish [7]
The equation would be x+15=46. I came up with this equation because we are given the total number of people at the reunion this year and we know how many more people are here this year than last year. The unknown is the number of people last year. That is why x would represent the number of people at the reunion last year because that is the unknown. If we add 15 to the number of people last year, it will give us 46( the number of people at the reunion this year).
To find x, we just use opposite operation to get the answer. Opposite of addition is subtraction so, we subtract the number of more people and the reunion this year from the total number of people at the reunion to get the unknown number of people at the reunion last year. 46-15 is 31. Therefore we know that 31 people were at the reunion last year
