Translate into mathematical expressions and Find the number.
Enter numeric answers. Use x as variable.
Five less than a number is seventeen
x-5 =17
x=17+5
x= 22 numeric answer

The total of twice a number and six is fourteen
2x + 6=14
2x + 6 - 6 = 14 - 6
2x / 2 = 8 / 2
x = 4 numeric answer

Twice the total of a number and three is fifteen
2(x + 3) =15
2x + 6 = 15
2x + 6 - 6 = 15 - 6
2x + 0 = 9
2x / 2 = 9 / 2
x = 4.5 numeric answer

Three more than three times a number is seven
3+3x = 7
3 - 3 + 3x = 7 - 3
0 + 3x = 4
3x / 3 = 4 / 3
x = 1 1/3 or 1.33

The product of five less than a number and two is six
(x - 5) 2 = 6
2x - 2 X 5 = 6
2x - 10 = 6
2x - 10 + 10 = 6 + 10
2x = 16
2x / 2 = 16 / 2
x = 8 numeric answer
Are these numeric answers correct ?

If a and b are fixed numbers, find parametric equations for the curve that consists of all possible positions of the point P in the figure, using the angle θ as the parameter. The line segment AB is tangent to the larger circle.

Here's the image (drawn very poorly be me, haha) that comes with the problem.

Ok, could somebody tell me if I did this question right?

The question is:
The derivative of f(x) is f'(x)=6x(2x-5)^2(3x+8)^3. Using interval notation, tell where f(x) is increasing and where it is decreasing.

So I solved 6x(2x-5)^2(3x+8)^3=0 and got the critical values of x=0, x=5/2, and x= -8/3. Are these right? I know this should be simple algebra but im blankinggg.

Next I found that f(x) is decreasing on the interval (-infinity,o] and increasing on [0, +infinity).

Is this right? Thanks to anyone who can help.

Peter says that the following equations are two ways to write the SAME formula. Solve them both for the same variable to decide whether or not you agree with Peter. Explain how you made your decision, based on solving for variables.

p = (r - 1)/r
(p equals r minus 1 over r)

p = r/(p + 1)
(p equals r over p plus 1)

thanks so much!

Two cars are traveling along perpendicular roads, car A at 40 km/hr east, car B at 20 km/hr south. When car A reaches the point where their paths have an intersection, car B is 100 km north of the intersection. Find the rate at which the cars are separating from one another 2 hours later.
I got 20 km/hr, but this seems wrong. I did the entire set up; I didn't just subtract the numbers. Can someone check my answer please, and explain if I'm wrong?
