Answer:
Divide −x - x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=−x3 f - 1 ( x ) = - x 3 is the inverse of f(x)=−3x f ( x ) = - 3 x
To find the number of red bricks used, you can create a part to part to whole ratio from the simple ratio of red to grey brick they give.
Then, use the total to create an equivalent ratio with the actual total number of bricks (140).
<u>5 red </u> <u>100 red</u>
<u>2 grey</u> = <u>40 grey</u>
7 total 140 total
<u>
</u>Each time, the simple ratio was multiplied by 20 to get the actual totals for each color.
<u>
</u>There were 100 red bricks used.<u>

It appears that none of your option choices are correct,, are you sure you copied them right ? I will show you how to solve this and how I got my answer.
The first step for solving this is to add the numbers in the parenthesis.
3 × 11 × 2 - 14 ÷ 7
Divide -14 by 7.
3 × 11 × 2 - 2
Divide the first 3 numbers together.
66 - 2
Subtract the numbers together to get your final answer.
64

Answer: D, 1/2
Step-by-step explanation:
4 country, 6 rap, 10 pop = 20 total
10 pop / 20 total
10 / 20 = 1/2
the slopes of these lines are equal when the determinant of the coefficient matrix is zero. Thus, for homogeneous systems we have the following result: A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero.
