I gave some examples of some quadrilaterals. The pond is most likely the shape of a square or a triangle with a right angle.
Answer:
D. (4, 5)
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
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
y = 1/2x + 3
<u>Step 2: Solve for</u><u><em> x</em></u>
- Substitute in <em>y</em>: x + 1 = 1/2x + 3
- Subtract 1/2x on both sides: 1/2x + 1 = 3
- Subtract 1 on both sides: 1/2x = 2
- Divide both sides by 1/2: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = 4 + 1
- Add: y = 5
<u>Step 4: Graph</u>
<em>We can confirm our answer.</em>
Answer:
{2.5, 5.0, 7.5, 10.0, 12.5}
Step-by-step explanation:
Next time, would you please type in the table vertically:
2 2.5
4 5.0
6 7.5
and so on.
The range consists of all the possible numerical outputs of the function for given inputs: {2.5, 5.0, 7.5, 10.0, 12.5}. Without knowing the outputs for other, unknown inputs, we cannot be more detailed in specifying the range.
-20% + 10 % = -10%
The ticket was less by 10 percent.
