To solve for the inverse of the function given;
We begin by re-writing the function as follows;
To now find the inverse, we interchange y for x, and vice versa, as shown below;
We now find the value of y;
ANSWER:
The correct answer is option B;
Answer:
2,160
Step-by-step explanation:
598 + 20 = 618
618 + 987 = 1,605
1,605 + 78 = 1,683
1,683 + 90 = 1,773
1,773 + 87 = 1,860
1,860 + 80 = 1,940
1,940 + 60 = 2,000
2000 + 70 = 2,070
2070 + 90 = 2,160
Answer:
Graph the triangle at points (1,5), (1,8), and (6,8)
Step-by-step explanation:
Since the rule is (x,y) -> (y,x), that just means swapping the value of x and y.
The first point (5,1) has 5 for x and 1 for y. If you swap the values, you get 1 for x and 5 for y, or (1,5).
The second point is (8,6). If you swap x and y you get (6,8). Notice I'm not doing the inverse of each number by making them negative, just swapping the twp values.
The third point is (8,1) and if you swap x and y you should get (1,8).
The transformation rule applies to ALL points, otherwise it wouldn't look right and it wouldnt be transforming.
I hope this helps :)
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
So, now that you have y, you can plug it into the first equation to find x:
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
