Solve the formula -4x -8y=16 foy y

aksik [14]

Answer:

All that's necessary is to add 4 to both sides of the equation. This gives

... y = 1/2(x -8) +4

If you like, you can simplify this by eliminating the parentheses and collecting terms.

... y = 1/2·x -4 +4

... y = (1/2)x

A solid with volume 8 cubic units is dilated by a scale factor of k to obtain a solid with volume V cubic units. Find the value

Katena32 [7]

Answer:

a. k = 27

b. k = 216

c. k = 0.216

Step-by-step explanation:

The value of the scale factor can be given by the following formula:

$k = \frac{Final\ Volume}{Initial\ Volume}$

where,

Initial Volume = 8 cubic units

Final Volume = 216 cubic units

Therefore,

$k = \frac{216\ cubic\ units}{8\ cubic\ units}$

k = 27

Final Volume = 1 cubic units

Therefore,

$k = \frac{216\ cubic\ units}{1\ cubic\ units}$

k = 216

Final Volume = 1000 cubic units

Therefore,

$k = \frac{216\ cubic\ units}{1000\ cubic\ units}$

k = 0.216

Suppose Miss Roxanne Davenport is 25 years old right now and puts away $1,800 per quarter in an account that returns 6% interest

Lena [83]

We have been given that miss Roxanne is 25 years old and she puts 1800 dollars per quarter that returns 6% interest.

(a) We need to figure out how much will be in the account when she turns 65 years old. When she turns 65 years old, the number of years during which she made deposits would be 40. Since she made quarterly deposits. She made a total of 160 deposits. We can now figure out the final amount in the account using future value of annuity formula.

$A=P\frac{(1+r)^{n}-1}{r}$
