Answer: 0
Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.
The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?
Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.

Step-by-step explanation:
<u>Step 1: Define Equation</u>
3.5(x + 12) = -2x + 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3.5: 3.5x + 42 = -2x + 18
- Add 2x on both sides: 5.5x + 42 = 18
- Isolate <em>x</em> term: 5.5x = -24
- Isolate <em>x</em>: x = -4.36364
Answer:
m(t) = 801 * (1/2)^(t/85)
Step-by-step explanation:
m(t) = 801 * (1/2)^(t/85)
m(t) is the mass after t days
