What is the solution to the system?

y = 4x + 20
8x - 2y = -20

Answers

Answer:

-no solution-

Step-by-step explanation:

When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.

you plug in that variable to the other equation

8x - 2(4x + 20) = -20

and then you just solve the equation from there.

8x - 8x + 20 = -20

but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.

The answers would be
1. Y=-5
2. 2.5

A wooden bench was originally priced at $50 but went on sale for 20% off. If Presley bought the wooden bench and paid a 5% sales tax, how much did he pay in total?

Answers

Answer:

$42.00

Step-by-step explanation:

20% OF  50 = 40

Before Tax Price: $40.00

Sale Tax: 5.00% or $2.00

After Tax Price: $42.00

Answer:

$42

Step-by-step explanation:

To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).

You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

Write your own real-world scenario where the Pythagorean Theorem can be applied to find a missing piece. You may choose to write a problem that is two- or three-dimensional in nature. Be sure that you will be able to draw a diagram of your scenario.

Write out your problem and submit it for Part 1. Be sure to end your scenario with a question.

Answers

Answer:

Supposed that you needed to know the diagonal distance from opposite corners of a rectangular prism.

d^2=x^2+y^2+z^2  where x, y, and z are the dimensions of the prism, or rectangular "box"

If the box has a width of 10, depth of 20, and a height of 30 then you have:

d^2=100+400+900

d^2=1400

d^2=100*14

d=√(100*14)

d=10√14 units

d≈37.42 units  (to nearest hundredth of a unit)

You might need this information to determine the most amount of space necessary to allow this box to pass through in any orientation...as the diagonal is the maximum dimension of the box.

I did a three-dimensional problem as the Pythagorean Theorem is often used only for two-dimensional problems in early mathematics.
