Answer:

(-3,-4)

Look at attached pictures for work and the text below for the explanation of the work. The brown numbers represent the step number it is.

Step-by-step explanation:

Start by getting either the x or y values in both equations the same number but opposite sign. Ex 16 and -16. I did x. Then add the equations eliminating one variable, in mine it was x, and the solve for the other variable, in mine it was y. Then plug that variable back into one of the two original equations and solve for the other variable, in mine I solved for x.

The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that

7x + 2x+27 = 180

Sum like terms:

9x+27 = 180

Subtract 27 from both sides:

9x = 153

Divide both sides by 9:

x = \dfrac{153}{9} = 17

Suppose you buy a CD for $300 that earns 3% APR and is compounded quarterly. The CD matures in 3 years. How much will this CD be
andrew-mc [135]

Given: Principal Amount (P) = $300

The rate of interest (r) = (3/4) compounded quarterly.

No. quarters in 3 years (n) = 3×4 = 12

To find: The amount for the CD on maturity. Let it will be (A)

Formula: Compound Amount (A) = P [ 1 + (r ÷100)]ⁿ

Now,   (A) = P [ 1 + (r ÷100)]ⁿ

or,            = $300 [ 1 + (3 ÷400)]¹²

or,            = $300 × [ 403 ÷ 400]¹²

or,            = $300 × 1.0938069

or,            = $ 328.14

Hence, the correct option will be C. $328.14

How do I do number 7 I wasn’t taught this
attashe74 [19]

The perimeter of the polygon will be (2x + 2xy + y + xz). Then the correct option is D.

<h3>What is a polygon?</h3>

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

The figure is given below.

The sides of the polygon are given as x, y, xz, x, xy, and xy.

Then the perimeter of the polygon will be

The perimeter of the polygon is given as the sum of all the sides of the polygon.

Then the perimeter will be

P = x + y + xz + x + xy + xy

P = 2x + y + 2xy + xz

More about the polygon link is given below.
