Answer:
y=2/3x-1
Step-by-step explanation:
The graphs are identical when you enter it into a graph calculator. the y&intercept is at -1 and the slope is 2/3. rise/run.
Answer:
What is the question? are we supposed to find something that equals r?
Answer:
Step-by-step explanation:
-5(y-15=3x) = -5y+75=-15x
add 15x to both sides and subtract 75 to both side
-5y+15x=-75
5y-2x=-3
13x=-78
and then both side divide by 13
x=-6
y-15=3(-6)
y-15=-18
Y= (-18) - 15 = -3
y=-3
and the answer will be (-6,-3)
hope that help you
Given:
Number of trips = 7
Distance from the school to the museum = 36 miles.
To find:
Write and solve equations to find how many miles the bus driver drove for the 7 trips.
Solution:
Let x be the number of trips and y be the total number of miles the bus driver drove.
Distance from the school to the museum = 36 miles.
1 trip means from the school to the museum and then from the museum to the school.
Distance covered in 1 trip = 2×36 = 72 miles.
Distance covered in x trips = 72x miles.
Substitute x=7 in the above equation to find the total distance the bus driver drove for the 7 trips.
Therefore, the bus driver drove 504 miles for the 7 trips.
Answer:
The probability is 0.857
Step-by-step explanation:
We know that:
There is a total of 440 cars
There are 63 cars with defective turn signals
There are 39 with defective tires.
Now we want to find the probability that a randomly selected car does not have defective turn signals.
If all the cars have the same probability of being selected, this probability will be equal to the quotient between the number of cars that do not have defective turn signals and the total number of cars.
We know that the total number of cars is 440
And 63 of these have defective turn signals, then the rest don't.
440 - 63 = 377 cars do not have defective turn signals.
Then the probability is:
P = 377/440 = 0.857
