First I would find out how many inches are burned away in 1 hour, 1 1/2 inches. then u multiply 3/4 by 4 to get 3. then u subtract the 3 by 10 to get 7 inches. the answer is 7 inches.
First u need to read the problem second annalyze 3 create ecuation 4 solve 5 write it in words
Change in y over change in x
If im understanding your post this is what i get
y − 4x = 72
+ y + 4x = 2
_________
2y= 74
Y= 72/2
Y= 36
y − 4x = 72
35-4x=72
-4x=72-35
-4x=37
X= 37/-4
X= - 37/4 or -9.25
Answer in point (-37/4, 36)

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
g(x) = 2|x| - 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function g(x)]: g(-2.3) = 2|-2.3| - 1
- Absolute values: g(-2.3) = 2(2.3) - 1
- Multiply: g(-2.3) = 4.6 - 1
- Subtract: g(-2.3) = 3.6
