Answer:
520<400+15x
15x>120
15x+400>520
Explanation:
Pay of Dan's car wash attendant job =$400 per week
The amount he earns per hour walking dogs = $15
Let the number of hours spent walking dogs in a week = x
Therefore, total earning for walking dogs =$15x
Since he wants to earn more than $520, we have that:
We can rewrite this as:
If we collect like terms, we have:
So the inequalities are:
0. 520<400+15x
,
1. 15x>120
,
2. 15x+400>520
Answer:
The probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.
Step-by-step explanation:
As the event is indicated as I for the drivers who are intoxicated, the value of I¯ is for the drivers who are not intoxicated. Its value is calculated as follows
P(I¯)=1-P(I)
P(I¯)=1-0.00589
P(I¯)=0.99411
So the probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.
Answer:
0
Step-by-step explanation:
f(6)= -6×2+2×6
f(6)= -12+12 = 0
I’m not 100% sure but I think it’s y=5x+20
Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
