The equation of the straight line PQ is 3-2kx+k+1=12,calculate,in each case,the numerical value of k if the line PQ is parrallel to the line y=4x+7;is perpendicular to the line y=4x+7;


that sounds like a problem about "slopes" so I am looking at using the derivative, which is basically the slope of the graph.
- the equation of line PQ can be simplified to y(x) = -2kx + k -8
- derivative relative to X (k is a constant) gives you -2k
- derivative of y(x) = 4x + 7 relative to x gives you 4

if the lines are parallel then the slopes are equal:
-2k=4 gives you k = -2 => your function becomes y = 4x - 8

if the lines are perpendicular the two slopes multiplied together give you -1:
-2k * 4 = -1 gives you k=1/8 => function becomes y = -1/4x - 7/8 or in other words y = -(2x+7)/8

I have made graphic representation and it looks to be correct.
I hope it makes sense.

Let f(x)=7x 2 ?4x+8 and g(x)=?6+4x?7x 2 . What is f(x)+g(x) ?


f(x) + g(x) would just be the two functions added together.

f(x) + g(x) = 7x 2?4x+8 + (?6+4x?7x 2)

Sorry, I don't understand your initial functions.

Good luck.

Q is inversely proportional to p cubed, when p is 2, q is 4 what is q when p is 5 what is p when q is 9?


q = x/(p^3) Substituting in 2 for p and 4 for q, we calculate x = 32 Now the formulas are q=32/p^3, or p=(cube root of 32/q)

How to calculate my grade based on total points?


to calculate your grade base on total points you have to know:
290 points represent the 100% so the question is how many percent is 232.17points.
x = (232.17x100) /290
x= 80%
and 80% is B-

Solve: 7(3x+5) = 8x - (1-4x)?


Let's rewrite as

7(3x+5) = 8x -1(1-4x)
Let's distribute
21x + 35 = 8x -1 + 4x
collect like terms
21x + 35 = 12x -1
Put all the x's on one side by subtracting 12x from both sides
21x -12x + 35 = 12x -1 -12x
simplify
9x + 35 = -1
get all the constants on the right side
9x + 35 - 35 = -1 - 35
9x = -36
divide both sides by 9 to get x by itself
9x /9 = -36/9
x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))
7(-12+5) = -32 - (1+16)
7 (-7) = -32 - (17)
-49 = -32-17
-49 = -49

Why is the North Pole so cold?


Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don't get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn't come up at all for months at a time.

Why does 1/5 + 1/2 not equal 2/7?


Let's look at the overall picture. Does it make sense if you have a fifth of a pizza and add a half pizza, you get less than a third of a pizza.

Now, into the math.
Here is a fifth of a pizza.


fifth pizza-t3nl2udzxv0orsigcra1nwzp-2-0.jpg Here is half a pizza.


half pizza-t3nl2udzxv0orsigcra1nwzp-2-2.jpg
It is hard to add these two.

We find the least common multiple of the denominators 2 and 5 and get 10.

Let's redo the pizzas in 10 slices.

two tenths-t3nl2udzxv0orsigcra1nwzp-2-5.jpg

And the half pizza.


five tenths-t3nl2udzxv0orsigcra1nwzp-2-9.jpg

Now with the same sized slices, we can add the slices and calculate the result.


seven tenths-t3nl2udzxv0orsigcra1nwzp-2-14.jpg Now we have seven slices out of ten, or 7/10.

Good luck.
