Answer:

$\sf b) \quad \dfrac{y^3}{4x}$

Explanation:

$\sf \left(\dfrac{6x^2}{5y}\right) \left(?}\right) = \left(\dfrac{3xy^2}{10}\right)$

cross multiply variables

$\sf ? = \left(\dfrac{3xy^2 (5y)}{10(6x^2)}\right)$

distribute inside parenthesis

$\sf ? = \left(\dfrac{15xy^3}{60x^2}\right)$

remove parenthesis and simplify

$\sf ? = \dfrac{y^3}{4x}$

Translate point A (2,5) 4 to the rt and up 3 what are the new<br> coordinates

Karolina [17]

Answer:

The new coordinates of the point are (6, 8)

Step-by-step explanation:

Suppose we have a point (x, y)

Let's define the translations:

For a positive number N:

A translation of N units to the right is written as (x + N, y)

A translation of N units to the left is written as (x - N, y)

A translation of N units upwards is written as (x, y + N)

A translation of N units down is written as (x, y - N)

Then if we have the point (2, 5) and we want to translate it 4 units to the right, the new point will be (2 + 4, 5) = (6, 5)

And now we want to do a translation of 3 units up, then the new point is (6, 5 + 3) = (6, 8)

The new coordinates of the point are (6, 8)

Please help me with all these questions . I really appreciate it but if you don't how to do it please comment don't answer the q

For number 1, add the sides of the triangle. They are all given. The answer is 19.

For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.

For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.

For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.

For number 5, add all the sides together like number 1. The answer is 18.

tensa zangetsu [6.8K]

Hello! Ok, so this is the formula x10 + 12 = 390 =
x10 + 12 - 12 = 390 - 12 = 378 =
x10 = 378 =
x10 / 10 = 378 / 10 =
x = 37.80$
He paid 37.80$ per payment
