N! means multiply the number by every number less than n
example 5! means 5 x 4 x 3 x 2 x 1
Answer:
Step-by-step explanation:
A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.
In your case, for every 40 boys, there are 20 girls. if we simplify this all the way down, we can get 2 to 1.
All of the following are ratios that apply to your question:
40 to 20
20 to 10
10 to 5
4 to 2
2 to 1

Answer:
y = -7/9 x +1
Step-by-step explanation:
7x + 9y = 9
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 7x from each side
7x -7x+ 9y =-7x+ 9
9y = -7x+9
Divide each side by 9
9y/9 = -7/9 x +9/9
y = -7/9 x +1
The slope is -7/9 and the y intercept is 1
My final answer is 7,376 degrees, increase.
X= -156 that is the real answer
