Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −5 and one-fifth.
Step-by-step explanation:
slope is the number next to x
The number of choice out of 7 that consumer have are 42.
<h3>What is permutation?</h3>
The term permutation alludes to a numerical computation of the quantity of ways a specific set can be sorted out. Set forth plainly, a change is a word that depicts the quantity of ways things can be requested or organized. With stages, the request for the course of action matters.
<h3>According to given data:</h3>
Number of choices of side dishes does a customer have,
total dishes(n)=7 , r = 2
ⁿP₂
⁷P₂
7×6 = 42
Thus required number of ways are 42.

Step-by-step explanation:
7x = 28

The "constant of proportionality" is the value that relates the two amounts<span>Example: you are paid $20 an hour (continued)<span>The constant of proportionality is 20 because:</span></span><span><span>Earnings = 20 × Hours worked</span></span>
<span><span />This can be written: y = kx</span>
<span><span>Where k is the constant of proportionality
</span></span>
<u>Part A and its work</u>
There is an ratio relationship between the hours and the amount paid. So for every hour you get paid 15$, You can figure this out by dividing the table for each amount of money earned by the time.45/3=15
75/5=15
120/8=15
150/10=15
<u>Part B and Its work</u>
Carl earns more money then louis because louis only makes 12$ per hour, It can even be shown in the chart below
Money||Money Earned
3 || 36
5 || 60
8 || 96
10 || 120
<u>Part C</u>
Make A coordinate grid, the X axis as time and the Y axis as money earned and plot the following coordiates (0,0) (1,15) (2,30)
