Answer:

The answer to your query would be the Third Answer Choice.

Step-by-step explanation:

> First we need to find where the point (3,0) lies on the graph. We can do this by looking at the x coordinate, being 3, and the y, being 0. Keep in mind that the solution is where the two lines meet, not where the point on the graph is.

> This gets us to 3 on the x line, and no further. We then need to find which has an intersection of both lines on that point. If it is not (0,3), it is not the correct answer, which we are looking for.

> The first graph has a solution of (0, -1.5), as this is where the lines intersect. This is not (3, 0), so this is not our answer.

> The second graph’s lines intersect at (0,1), and since that is the solution of the graph, it is not the correct answer.

> The third graph’s lines intersect at (3, 0), and since this is it’s solution, it is the correct answer. Since we cannot be 100% sure, we still need to continue with checking the last graph.

> The fourth and last graph’s lines meet at (0,3), which is not what we are looking for, and is henceforth wrong.

> Once again, the correct answer is the Third Answer Choice. All the other graph’s have solutions on points other than (3,0), so they are not our answers.

> I hope this answered your query and any other questions you may have had on the subject. #LearningWithBrainly

75 POINTS Need an immediate answer please brainliest will be given! A train left a station travelling to a city at 30 mph. The t
yaroslaw [1]

The value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

<h3>What is the rate of speed?</h3>

The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,

r=d/t

Here, (d) is the distance travelled by the object and (t) is time taken but the object to cover that distance.

The train traveled 1/3 of the distance at 30 mph and the remaining distance at 40 mph. Let <em>t</em> is the time the train has taken to travel and x is the distance it travelled. Thus,

t=\dfrac{\dfrac{1}{3}x}{30}+\dfrac{\dfrac{2}{3}x}{40}\\t=\dfrac{x}{90}+\dfrac{x}{60}\\t=\dfrac{2x+3x}{180}\\t=\dfrac{5x}{180}\\t=\dfrac{x}{36}

After two hour a car left the same station traveled the first 3 hours at 35 mph and the remaining distance at 51 mph. Let <em>t</em> is the time the car has taken to travel and x is the distance it travelled. Thus,

t+2=3+\dfrac{(x-3\times35)}{51}

As t is same, thus put the value of t in this equation,

\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=1+\dfrac{(x-105)}{51}\\\dfrac{x}{36}=\dfrac{(51+x-105)}{51}\\51x=36x-54\times36\\51x-36x=1944\\x=\dfrac{1944}{15}\\x=129.6

Thus, the value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

Write an inequality, in slope-intercept form, for the graph below. If necessary,
d1i1m1o1n [39]

Answer:not 100 % sure but I can write a slope intercept form equation, but not an inequality. I would need a picture of the graph to write an inequality.

First find slope: (y2 - y1)/(x2 - x1)   Slope is 3

Choose a point then use point slope form y - y1 = m(x - x1)      It is y - 1 = 3(x - 1)

Now simplify:

y - 1 = 3(x - 1)

y - 1 = 3x - 3

y = 3x - 2

y = 3x - 2

PLEASE HELP ME I NEED IT<br> X=<br> Y=
vampirchik [111]
X=33 and Y= 57



Step by step explanation if you see the right angle at 57 degrees it part of x so x plus 57 is 90 and 90 minus 57 is 33 so x is 33 and x and y also form a right angle so x plus y should equal 90 and 90 minus 33 is 7 so that’s Y
