Answer:
Step-by-step explanation:
We would have to convert the standard equation into slope-intercept form.
======================================
<h3><u>Converting the equation into Slope-Intercept Form:</u></h3>
<u />
======================================
<h3><u>Identifying the Slope and Y-Intercept:</u></h3>
<em>General slope-intercept form is: </em>
<em></em>
<u />
In the equation 
, '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.
<em>Therefore:</em>

Answer:
8 < 8.2 <8.5
Step-by-step explanation:
Pick a number that is greater than 8 but less than 8.5.
Ex: 8.1, 8.2, 8.3, 8.4
Hey there! :)
Answer:
arc AB = 2.5π in (in terms of pi) or ≈7.85 in. (pi = 3.14)
Step-by-step explanation:
Begin by finding the circumference of the circle. Use the formula:
C = 2rπ
C = 2(9)π
C = 18π.
Since ∠AQB equals 50°, set up a ratio to find the length of arc AB:
Cross multiply:
50 · 18π = 360x
900π = 360x
Divide both sides by 360:
x = 2.5π in, or ≈7.85 in.
Answer:
Step-by-step explanation:
Show that if 3x – 7 = 5, then x = 4.
Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.
x=4
Statements Reasons
1. 3x – 7 = 5 Given
2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)
3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)
4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)
5. 3x = 12 Substitution of 5 + 7 = 12 into (4)
6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3
7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)
8. x = 4 Substitution of 12⁄3 = 4 into (7)
Is there such a thing as being too descriptive? Yep, and that was it, since over half the proof was devoted to telling the reader how to do arithmetic. We'll typically take numerical computation for granted, and write proofs like this:
