Instead use WolframAlpha.com for math questions  I would paste the answer but a cretinous fop has "disabled" that feature by javascript -- which is trivial to circumvent but I won't bother with the time.

vazorg [7]

Answer: 747


Step-by-step explanation:

16x9+67x9

First multiply 16 and 9 which is equal to 144

144+67x9

now multiply 67 and 9 which is equal to 603

144+603

Now add 144 and 603 which is equal to 747

So the answer to 16x9+67x9 is 747

What is the slope of the line that passes through the pairs of points (-6,8) (2'3)
Alecsey [184]
Im pretty sure the answer is D, because if i used the right formula,
\frac{y2 - y1}{x2 - x1}
you should get this in the formula
\frac{8 - 3}{2 - ( - 6)}
\frac{5}{8}
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8

√32x^10y^n simplies to 4x^5y^3√2y

Then n = 7 because √y^7 = √(y^6 * y) = y^3√y

So √32x^10y^7 = 4x^5y^3√2y

Answer

n = 7
