Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x - 2y = 2
4x - 2y = -8
<u>Step 2: Rewrite Systems</u>
-x - 2y = 2
- Multiply both sides by -1: x + 2y = -2
<u>Step 3: Redefine Systems</u>
x + 2y = -2
4x - 2y = -8
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 5x = -10
- Divide 5 on both sides: x = -2
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 4x - 2y = -8
- Substitute in <em>x</em>: 4(-2) - 2y = -8
- Multiply: -8 - 2y = -8
- Isolate <em>y</em> term: -2y = 0
- Isolate <em>y</em>: y = 0
Answer:
Well, there are 60 min. in one hour, so 10*6=60. Then we have to multiply 3 by 10 as well. So the answer is D: 30 busses.
The Subtraction Property of Equality is the correct answer !!
Answer:
y-8=5(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-2-8)/(2-4)
m=-10/-2
m=10/2
m=5
y-8=5(x-4)
