Answer:
D. (1, -2)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
5x - 2y = 9
3x + 4y = -5
<u>Step 2: Rewrite systems</u>
10x - 4y = 18
3x + 4y = -5
<u>Step 3: Solve for </u><em><u>x</u></em>
- Add to equations together: 13x = 13
- Divide 13 on both sides: x = 1
<u>Step 4: Solve for </u><em><u>y</u></em>
- Define: 3x + 4y = -5
- Substitute in <em>x</em>: 3(1) + 4y = -5
- Multiply: 3 + 4y = -5
- Isolate <em>y </em>term: 4y = -8
- Isolate <em>y</em>: y = -2
And we have our final answer!
8^2 is 64 and 8^7 is 2097152 and do 64*2097152 which is 134217728.
The answer is b because is is the only one that matches
If the function is vertically compressed, the resulting function will be g(x) = 3/4x^2
<h3>Vertical compression of a function</h3>
Quadratic functions are functions that has a leading degree of 2. Given the parent function f(x) = ax^2
where
2 is the exponent/degree
If the function is vertically compressed, the value of a must be less than 1, hence the possible expression when vertically compressed is g(x) = 3/4x^2

In getting the scale factor, use the formula:
Scale factor = big / small
Scale factor = 8 / 2
Scale factor = 4 units
