Answer:

The graph that represents the system is:

A graph that for y = 3 cuts the axis at point 3 and for x + y = 4 cuts the graph in the coordinates (0, 4), (1, 3), (2, 2), (4, 0) and others that comply with the rule that when added they give a value of 4.

Exact graph as an annex.

Step-by-step explanation:

As you can identify in the graph that is in the annex, the fragment y = 3 (differentiated with red color in the graph) refers to the fact that the Y-axis is going to be cut at point 3 with a continuous horizontal line, while the fragment of the system x + y = 4 (differentiated with blue color in the graph) refers to all those values of X and Y that when added together give a value of 4, in the answer I have given you the examples that more are denoted in the graph, but you can take others like (5, -1) since if you add them:

-1 + 5 = 4

The final value of 4 given by the equation is still maintained.

Find the value of x and. Will mark brainliest.

Sindrei [870]

Answer:

x=5

y=25

Step-by-step explanation:

You can start by finding the value of x. Since opposite angles in a parallelogram are equal, 11x=55 and x=5. Since adjacent angles are supplementary, 5y+55=180, 5y=125 and y=25. Hope this helps!

Esther drove to work in the morning at an average speed of 45 miles per hour. She returned home in the evening along the same ro

nydimaria [60]

The key is Esther travelled the same distance - x - in both her morning and evening commute.

45(time she took in the morning, or p) = x
30(time she took in the evening, or q) = x

Therefore 45(p) = 30(q), or divide both sides by 5 and get 9(p) = 6(q). I know you can divide it further, but these numbers are small enough and it's not worth the time.

Since the whole trip took an hour, (p + q) = 60min, and so, p = 60-q.

Therefore 9(60-q) = 6q or 540-9q = 6q. So 540 = 15q, which makes q = 36. If q = 36, then by (p+q)=60, p (the time she took in the morning) must equal 24.

45 miles per hour, her speed in the morning, times (24/60) hours, her time, makes 18 miles travelled in the morning. If you check, 30 miles per hour times (36/60) hours also makes 18 miles in the evening.

Hope that makes a little sense. And I also hope it's right

PLEASE HELP ME, I HAVE NO IDEA! Find an equation for the line below.

irga5000 [103]

9514 1404 393

Answer:

y -2 = -2/3(x +4)

Step-by-step explanation:

There are several different forms of the equation for a line. Each is useful in its own way. Here, the line crosses the y-axis at a point between integer values, so using that intercept point could be problematical. That suggests the "point-slope" form of the equation for a line would be a better choice.

That form is ...

y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

The two marked points are (-4, 2) and (5, -4). All we need is the slope.

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1) . . . . . . . . where the given points are (x1, y1) and (x2, y2)

m = (-4 -2)/(5 -(-4)) = -6/9 = -2/3

Using the first point, the equation for the line can now be written as ...

y -2 = -2/3(x -(-4))

y -2 = -2/3(x +4)
