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.
Answer:
40,000
Step-by-step explanation:
because of the 5 in the thousands place means were rounding up
Answer:
x = 64°
Step-by-step explanation:
180° in half a circle or a line.
There is also 180° in a triangle.
So the other 2 angles of the triangle equal x.
34° + 30° = 64°
