Answer:
[2], [5], [8],
Step-by-step explanation:
Answer:
I assume by standard you mean simplified. Anyways, the answer is -5h-2.
Step-by-step explanation:
3h-2(1+4h)
Solve inside the parenthesis.
3h-2+(-8h)
Simplify.
-5h-2
Number the tables as follows:
1 2
3 4
Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).
In tables 1 and 2, the input (1) produces the correct output (-1).
So we have to determine which table agrees 100% with the system of equations given.
Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.
First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).
Thus, table 1 correct represents the solution of the system of equations.
To answer, find the distance from point C to D, point D to E, point E to F, and point F to C. The formula for the distance is,
d = sqrt ((x2 - x1)² + (y2 - y1)²)
Point C to D d1 = sqrt ((-3 - -2)² + (1 - 4)²) = 3.16 units
Point D to E d2 = sqrt ((1 - -3)² + (0 - 1)²) = 4.12 units
Point E to F d3 = sqrt ((-1 - 1)² + (2 - 0)²) = 2.83 units
Point F to C d4 = sqrt ((-1 - -2)² + (2 - 4)²) = 2.23 units
Then, add up all the distances and the answer is 12.34 units. The closest answer is letter D. Credit:Meerkat
