<h3>Given</h3>
P = 3r + 2s
<h3>Find</h3>
the corresponding equation for s
<h3>Solution</h3>
First of all, look at how this is evaluated in terms of what happens to a value for s.
- s is multiplied by 2
- 3r is added to that product
To solve for s, you undo these operations in reverse order. The "undo" for addition is adding the opposite. The "undo" for multiplication is division (or multiplication by the reciprocal).
... P = 3r + 2s . . . . . . starting equation
... P - 3r = 2s . . . . . . -3r is added to both sides to undo addition of 3r
... (P -3r)/2 = s . . . . . both sides are divided by 2 to undo the multiplication
Note that the division is of everything on both sides of the equation. That is why we need to add parentheses around the expression that was on the left—so the whole thing gets divided by 2.
Your solution is ...
... s = (P - 3r)/2
Answer: The dryer cost $375.
Step-by-step explanation:
676 - 74 = 602
602/2 = 301
301 + 74 = 375
It is an easier and faster way to write an equation for the slope of a line if you already have its points and slope.
Answer:
$24,498,509.74
Step-by-step explanation:
The formula for the value as a function of time is ...
V(t) = P·e^(rt)
Filling in the numbers and doing the arithmetic, we have ...
V(35) = 3,000,000·e^(0.06·35) ≈ 24,498,509.74
Compounded continuously for 35 years, the investment will be worth $24,498,509.74.
It’s a. vertex is the lowest or highest point so (1,-8) x-intercepts is where the parabola hits the x axis so (-1,0) and (3,0)
