The distance, s = 40t₁ where t₁ is the time to complete the outward journey.
The same distance = vt₂ where t₂ is the time to complete the return journey at speed v.
For the whole journey, 2s=60(t₁+t₂). Therefore s=30(t₁+t₂)=40t₁=vt₂.
30t₁+30t₂=40t₁, 10t₁=30t₂, t₁=3t₂, so s=120t₂=vt₂ and v=120kph.
Answer:
How much will you save if you take the better deal?
Antole Store discount: $ 45.96 x 20% = $ 9.99
Sergei Store Discount: $ 46.75 x 25% = $ 11.69
If you buy at a Sergei store, you get a discount on your payout compared to an Antole store of $ 1.7
Step-by-step explanation:
It makes a zig zag across the graph so i think none of the above
If the equation of the absolute value function is f(x) = |x + 1| + 7, then the range of the function is -∞ < y ≤ 7
<h3>How to determine the range of the absolute value function?</h3>
<em>The question is incomplete, so I will provide a general explanation</em>
Assume that the absolute value function is given as:
f(x) = |x + 1| + 7
Set the absolute value to 0
f(x) ≥ 0 + 7
Evaluate
f(x) ≥ 7
This means that the smallest value of the function is 7
Hence, the range of the absolute value function is -∞ < y ≤ 7
