Direct variation means their ratio is a constant
x/y is 9/45=1/5
so when x=2, y=5*2=10

a • (6ab2 + 2ab - 2a - 3b2 + 4b)

Step by step solution :Step 1 :
Equation at the end of step 1 : (3ab • (2ab + 2a - b)) - 2a • (2ab + a - 2b) Step 2 :Equation at the end of step 2 : 3ab • (2ab + 2a - b) - 2a • (2ab + a - 2b) Step 3 :Step 4 :Pulling out like terms :

4.1 Pull out like factors :

 6a2b2 + 2a2b - 2a2 - 3ab2 + 4ab =

 a • (6ab2 + 2ab - 2a - 3b2 + 4b)

Final result : a • (6ab2 + 2ab - 2a - 3b2 + 4b)

The weight of gemstones, such as diamonds, rubies, and emeralds, is measured in carats. A carat is a unit of measure equal to 20

Alexxx [7]

We are told in the question that 1 carat is equal to 200 mg.

The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

$\frac{200mg}{1 carat}* \frac{44.5 carats}{1}=8,900 mg$

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

$\frac{8,900mg}{1000}=8.9grams$

Now we know that the weight of the Hope Diamond is equal to 8.9 grams.

Answer:

f(7) - f(-7)

= (4 - 7^2) - ((-7)^3 - 2*(-7))

= -45 - (-329)

= 284
