Divide any term by the term before it, and you'll get the common ratio of the geometric series.

-81/-27=3
The common ratio is 3.

Answer:

The common ratio is 3

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

-9/-3 = 3

We can check by dividing the third term by the second term

-27/-9 =3

Bananas cost 0.59 per pound. Create an equation that could be used to find the total cost of y of x bananas
n200080 [17]

Answer:

y = 0.59x

Step-by-step explanation:

Cost per pound of banana = $0.59

If Number of banana's = x

Total Cost of an item = price per item * number of items

Therefore,

Total cost, y = price per pound of banana * number of bananas

y = 0.59 * x

y = 0.59x

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Check all that apply.
jonny [76]
First, we find the slope of the given line.

<span>3x − 4y = 7

-4y = -3x + 7

y = (3/4)x - 7/4

The slope of the given line is 3/4.
The slope of the parallel line is also 3/4.

Now we need the equation of the line that has slope 3/4 and passes through point (-4, -2),

We use the point-slope form of the equation of a line.

y - y1 = m(x - x1)

y - (-2) = (3/4)(x - (-4))

y + 2 = (3/4)(x + 4)     <---- check option E. Is the fraction 3/4 not there?

y + 2 = (3/4)x + 3

y = (3/4)x + 1

4y = 3x + 4

3x - 4y = -4    <------ this is choice B.
