No they are no proportional. If you travel 60 miles in 2 hours, it is the same thing as driving 30 miles in 1 hour. When you travel 6 miles, you would travel 180 miles but it is not shown like that. That is why it is not proportional. They don't go through a constant rate of change.
Answer:
k=1
Step-by-step explanation:
<h3>first step:</h3>
k=1*1=1
<h3>second step:</h3>
6*k | 6*1=6
<h3>third step:</h3>
1-6= -5
<h3>fourth step:</h3>
-5 + 14=
the answer:
<h2>9</h2>
Answer:
w = 9 or w = 1
Step-by-step explanation:
4|w − 5| = 4
Divide both sides by 4
w - 5 = 4 w - 5 = -4
+ 5 + 5 + 5 + 5
w = 9 w = 1
Answer: $12 an hour
Step-by-step explanation:
Rosey works 37 hours a week and 4 weeks in a month.
Total hours are:
= 37 * 4
= 148 hours
In order to at least cover the $1,776 in expenses she incurs every month, Rosey's hourly pay must be:
= expenses / working hours in month
= 1,776 / 148
= $12 an hour
Answer:
Step-by-step explanation:
hello :
15r² – 6r – 3 = -2r
15r² – 6r – 3 +2r =0
15r²-4r -3 =0
delta =b² -4ac a=15 b=-4 c=-3
delta =(-4)² - 4(15)(-3)=196 = 14²
r1 = (-b - √delta ) /2a = (4-14)/30 = -10/30 = -2/6 = -1/3
r2 = (-b + √delta ) /2a = (4+14)/30 = 18/30 = 3/5
