Answer:
In the year 2010, the population of the city was 175,000
Step-by-step explanation:
If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
Answer:
40
Step-by-step explanation:
d=rt
300=r(7.5)
300÷7.5=r
40=r

Answer:
Well if your going 3miles per hour and it 1.5 hours than it would take about...half an hour 30mins
Step-by-step explanation:
Okay so first let’s set one of the two equations equation to one of the two variables
I’m going to pick the second equation and y
So
x+y=10
y=10-x
Now let’s bring the other equation in and substitute y for 10-x
2x+3y=45
2x+3(10-x)=45
Now solve for x
2x+3(10-x)=45
2x+30-3x=45
-x+30=45
-x=15
x=-15
Okay so now we have x = -15 now let’s find y by using the original equation I moved around and pigging in y like
y=10-x
Plug in x
y=10-(-15)
y=10+15
y=25
So now that I look back at the program you only needed x but her is x and y I hope I helped
