Answer:
72$
Step-by-step explanation
How to insert in a calculator 90-20%= 72
How to take 20% from a price
Divide the original price by 5. <em>18</em>
Subtract this new number from the original one. <em>90 - 18 </em>
The number you calculated is the discounted value. <em>90 - 18 = </em><u><em>72</em></u>
The attached graph represents the piecewise function.
<h3>How to determine the graph of the equation?</h3>
The piecewise function is given as:
f(x) = 3x - 5, x ≤ -1
= -2x + 3, -1 < x < 4
= 2, x ≥ 4
To plot the graph, we simply plot the equations together with their domains
i.e.
3x - 5 with the domain of x ≤ -1, -2x + 3 with the domain of -1 < x < 4 and 2 with the domain of x ≥ 4
See attachment for the graph of the function

Answer:
280 and 8
Step-by-step explanation:
the LCM is the lowest common multiple
the lowest multiple that can Divide 40 and 56 without a remainder = 280
the Hcf Is the highest common factor of 40 and 56
the highest number that can Divide both =8
