Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.

This looks pretty challenging. If this algebra problem (Which looks like it is) or not, you could find some video explanations on Khan Academy, just pick the category in the math section and hopefully you can somewhat understand you problem more clearly.

Answer:
Step-by-step explanation:
From the given information:
Given that the solution is pumped at a slower rate of 4gal/min
Then:
The differential equation can be expressed as:
Integrating the linear differential equation; we have::
multiplying above integrating factor fields; we have:
A = (50 + t) + c(50 + t)²
Using the given conditions:
A(0) = 20
⇒ 20 = 50 + c (50)⁻²
-30 = c(50) ⁻²
c = -30 × 2500
c = -75000
A = (50+t) - 75000(50 + t)⁻²
The no. of pounds of salt in the tank after 35 minutes is:
A(35) = (50 + 35) - 75000(50 + 35)⁻²
A(35) = 85 -
A(35) =69.6193 pounds
A(35) 70 pounds
Thus; the number of pounds of salt in the tank after 35 minutes is 70 pounds.
