If you would like to write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck, you can calculate this using the following steps:
X ... the amount of Alicia's paycheck
X/2 - $42.15 >= $20
X/2 >= $20 + $42.15
X/2 >= $62.15 /*2
X >= $62.15 * 2
X >= $124.3
The correct result would be <span>X >= $124.3</span>.
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:
The answer is 8/9x + 2484/7
Answer:
C = 18.84
Step-by-step explanation:
C= 2*pi*r
C= 2*3.14*3
C= 6.28*3
C= 18.84
