<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Slope Formula:
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Find points from chart.</em>
Point (39, 36)
Point (40, 29)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:
- Subtract:
- Divide:
The equation for slope is:
(y2 - y1) / (x2 - x1)
-2 -(-7) = 5
-9 -(-1) = -8
Slope of the line:
5/-8 or -5/8
Answer:
x=4
Step-by-step explanation:
8x+5=10x-3
+3. +3
8x+8=10x
-8. -8
8=2x
/2. /2
x=4
Step-by-step explanation:
Add 75 to 12.55. the answer would be 87.55.
100+105=205
205-87.55=117.45
Answer: The 9 in the second term is a coefficient that is true. I think that is the only thing that is true. There may be one more thing that is true.
The 10 in the third term is not a coefficient.
The 2 is not a constant
the x is not an exponent.
those are the ones that I'm sure about.
Please correct anything if i'm wrong.
