<h3><u>Question:</u></h3>
On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.
<h3><u>Answer:</u></h3>
y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.
<h3><u>Solution:</u></h3>
Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars
Let "y" be the value in dollars
Let "x" be the number of euros
We have to write a equation in form of y = kx
<em><u>8 euros were worth 9 dollars</u></em>
"k" is found as follows:
Therefore, equation of y = kx is given as:
To check the equation, use the another given value
24 euros were worth $27
Hence the equation y = 1.125x is correct
The product is less than either of the factors. Multiplying a number < 1 with 2/3 another number < 1, will give a fraction of a fraction, and part of a fraction is an even smaller fraction. Another way of looking at it: Fractions less than one have numerators smaller than their denominators. When multiplying fractions, you multiply across, so multiplying two fractions that are both less than one will always give a numerator much smaller than the denominator, and a larger denominator makes for a smaller number. I hope this helps, but if you have questions, ask.
It helps to imagine the variable a sort of as a unit. Like with 5 minus 12 lemons, it has no bearings on the addition/subtraction here.
Factor out a and subtract.
Answer:
m=0
horizontal line
Step-by-step explanation:
Given two points, we can find the slope from
m = (y2-y1)/(x2-x1)
= (1-1)/(-3-2)
=0/-5
The slope is 0
The line is horizontal
