HELP ME PLEASE! I WILL GIVE BRAINLIEST LOTS OF POINTS

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.

I'm not sure how I'm supposed to use this equation.can someone help me and explain?

So QRS equals to 158 degrees. Therefore, you need to do 8x+8+2x=158. This is so then you can find x. In order to find x, you'll need to combine the 2x and 8x(10x+2=158). Then subtract 2 from both sides(10x=156). Finally divide by 10(x=15.6). In order to find TRS, multiply 15.6 by 2 to get the angle measure. If you want to find QRT, plug 15.6 into the equation(multiply 8 and 15.6 and add 8=132.8)

Brums [2.3K]

Answer:

please see explanation.

Step-by-step explanation:

2268×2=4536

2268×3=6804

2268×4=9072

2268x5=11340

2268×6=13608

2268×7=15876

from the computation 15848 is a perfect square

√15848= 126

to calculate the 126= ✓126=11.225
