What does 18x + 2y = 12 equal?

1 answer:

3 0

18x + 2y = 12 equals y = -9x + 6 because you would move 18x to the other side which would make it a negative and divide with 2y and you would get your answer.

Answer:

True

Step-by-step explanation:

The formula for the area of a circle is πr² where r is the radius. So if 3 is the radius, plug it into the formula:

π(3²)

Simplify it:

π(9)

This can be rewritten as:

9π

So, the answer is true

Answer:

The answer to your question is: r = 0.1

Step-by-step explanation:

Data

P = $4500

A = $9000

t = 9 years

r = rate

Formula

$r = \sqrt[t]{\frac{A}{P}} - 1\\$

Substitution

$r = \sqrt[9]{\frac{9000}{4500} - 1\\$

Simplification

$r = \sqrt[9]{2} - 1$

Result

r = 1.08 - 1

r = 0.08 ≈ 0.1

4|2x+7|=16 x=? and x=?

sammy [17]

4 | 2x + 7 | = 16...divide both sides by 4
| 2x + 7 | = 16/4
| 2x + 7 | = 4

2x + 7 = 4 -(2x + 7) = 4
2x = 4 - 7 -2x - 7 = 4
2x = -3 -2x = 4 + 7
x = -3/2 -2x = 11
x = -11/2

so x = -3/2 and x = -11/2
