Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Answer:
x = -8
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
-1x = -8 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: -x = -8 - 2x
- Add 2x on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -1(-8) = -8 - 2(-8)
- Multiply: 8 = -8 + 16
- Add: 8 = 8
The correct order of reasons that complete the proof about the rectangle and square is that D. definition of congruence, distance formula if two consecutive sides of a rectangle are congruent, then it's a square.
<h3>What is congruence?</h3>
It should be noted that congruence simply means an agreement or a correspondence between shapes.
In geoemtry, it should be noted that figures are said to be congruent if it is possible to superpose one of them on another.
It should be noted that the opposite sides of a rectangle are parallel while in a square, all the sides that are given are equal.
Therefore, the correct order of reasons that complete the proof about the rectangle and square is the definition of congruence, and that if two consecutive sides of a rectangle are congruent, then it's a square.
In conclusion, the correct option is D.

Answer:
- y = 3x + 4
- y =
x - 1 - y = 4
- undefined
Step-by-step explanation:
Slope-intercept form is written in the form: <em>y </em>=<em> mx </em>+<em> b</em>. Leave the y and x as they are. The m is the slope of the graph. The b is the y-intercept of the graph. For number three, the slope of a horizontal line is 0. For number four, the slope of a vertical line is undefined.
Hope it helps! (I'm not sure if you need the answers to the bottom questions).
