Answer:
(3, -9)
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>
-5x - 3y = 12
y = x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - 3(x - 12) = 12
- Distribute -3: -5x - 3x + 36 = 12
- Combine like terms: -8x + 36 = 12
- Isolate <em>x</em> term: -8x = -24
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 12
- Substitute in <em>x</em>: y = 3 - 12
- Subtract: y = -9
<u>Step 4: Graph systems</u>
<em>Check the solution set.</em>
Answer:
1145
Step-by-step explanation:
- <em>The upper bound is the smallest value that would round up to the next estimated value</em>.
Since the number was rounded to nearest ten, the upper bound is:
which rounds up to 1150 which is the next estimated value greater than 1140
Answer:
Step-by-step explanation:
A well defined set is one which is universally defined and accepted, you can easily define what the set is and what is not a member of the set.example is a set of integers between 1 and 30
A not well defined set is one which is ill defined set. example is a list of hit musical hit of 2019
