I believe the ansr would be (-6,-4) I say this becuase if it's positive on the y axis the X axis will be negative and if it's being reflected the coordinates will be backwards. If this answer is wrong I'm truly sorry, but I hope this helps!

Identify the 34th term of the arithmetic sequence 2, 7, 12

torisob [31]

The equation is AN=A1+D(N-1) A1 being the first number (2) D being the difference (in this case 5) and N being the nth term to find (34) so here you have AN=2+5(34-1) then AN=2+5(33). the answer here is 167.

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from graph.</em>

Point (1, -5)

Point (7, -1)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute [SF]: $m=\frac{-1+5}{7-1}$
Add/Subtract: $m=\frac{4}{6}$
Simplify: $m=\frac{2}{3}$

Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minut

velikii [3]

Let c be total cost, while m is the minutes above the base minutes;
C=34.99+0.23*m
C=34.99+0.23m
Note, m= total minutes - 100
