Slope = raise / run
(211.1 - 212.0) / (0.5-0) = - 1.8
(210.2 - 211.1) / (1.0-0.5) = - 1.8
(208.4 - 210.2) / (2.0 - 1.0) = - 1.8
You can check, the other points. The slope is constant because the function is a linear equation,
Answer: - 1.8
For a rational number to have a terminating decimal expansion
q should be in the form 5^m and 2^n or both. If q is not in the form of either then it is a non terminating recurring decimal expansion
Answer:
(-3, 4)

- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define Systems</u>
16x + 14y = 8
-63x - 14y = 133
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations: -47x = 141
- Divide -47 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: 16x + 14y = 8
- Substitute in <em>x</em>: 16(-3) + 14y = 8
- Evaluate multiplication: -48 + 14y = 8
- Add 48 on both sides: 14y = 56
- Divide 14 on both sides: y = 4
<u>Step 4: Graph Systems</u>

(4/7)w = 12/7
w = (12/7) / (4/7)
w = 12/7 * 7/4
w = 84/28 = 3....it would take 3 weeks
