Answer:
<h2>3.05x(output for x)</h2><h2>39.65</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
according to the question
the function is
f(x)=3.05x(first answer)
let's justify
f(1)=3.05×1
=3.05
LIKEWISE
f(3)=3.05×3
=9.15
therefore
it is the function
answer for the second question
f(13)=3.05×13
=39.65
Answer:
50

Answer:
slope can only be showed by the word <em><u>GRADIENT</u></em>
Step-by-step explanation:
A <em>slope</em><em> </em>means how much something is <em>slanting</em>
like if something is <u>Inclined</u><u> </u>at a specific degree. e. g. <em>This</em><em> </em><em>house</em><em> </em><em>is</em><em> </em><em>inclined</em><em> </em><em>at</em><em> </em><em>4</em><em>5</em><em>°</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>road</em>
Vertex = 1,4

<span>The distance between two cities is ninety miles, and a woman drives from one city to the other at a rate of 45 mph. At what rate must she return if the total travel time is three hours and forty minutes?
1st leg DATA:
distance = 90 mi ; rate = 45 mph ; time = d/r = 2 hrs.
</span><span>2nd leg DATA:
distance = 90 mi ; time = [3 2/3 - 2] = 1 2/3 hrs; rate = 90/(5/3) = 54 mph
Ans: 54 mph</span>
