Answer:

Step-by-step explanation:

4u + 8v = -3u + 2v

Solving 4u + 8v = -3u + 2v

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '3u' to each side of the equation. 4u + 3u + 8v = -3u + 3u + 2v

Combine like terms: 4u + 3u = 7u 7u + 8v = -3u + 3u + 2v

Combine like terms: -3u + 3u = 0 7u + 8v = 0 + 2v 7u + 8v = 2v

Add '-8v' to each side of the equation. 7u + 8v + -8v = 2v + -8v

Combine like terms: 8v + -8v = 0 7u + 0 = 2v + -8v 7u = 2v + -8v

Combine like terms: 2v + -8v = -6v 7u = -6v

Divide each side by '7'. u = -0.8571428571v

Simplifying u = -0.8571428571v

You need to buy a new cover for a pool.The pool is in shape of a trapezoid.The cost of the cover is .79.What is the total cost
jek_recluse [69]
Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.

First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.

A = 0.5(h)(the sum of the bases)

Once you have the area, multiply by 0.79 and you will have the cost.

Please help means a lot
sattari [20]

Answer:

y = -1/4x + 3

Step-by-step explanation:

you got to do the inverse, so like this

y = 4x > y = -1/4x

then you do take the coordinates (4,2) and put them into place like this:

y - 2 = -1/4(x - 4) > y - 2 = -1/4x +1 (four times -1/4 = 1)

then add the -2 on both sides

y = -1/4 + 3

:)
