Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
4 0

Answer:

A

Step-by-step explanation:

We graph two variable inequalities like we graph line equations. First, read the inequality as y\geq mx+b where m is the slope and b is the y-intercept. Here b= 2. Go to the y-axis and mark a point on 2. From here, go up 3 and over 2. Mark the point at (2, 5).  Since the inequality does not have an "equal to" draw a dashed line is drawn between the points with arrows on either end. To finish, test an (x,y) point to determine what makes the inequality true.  

Choose any (x,y) point not on the line. Say (0,0).

y < \frac{3}{2}x + 2\\0

Is the statement true? Yes. This means shade this side of the line.

Solution A matches this.

  • If it lies on x- axis, it has zero y-coordinate
  • It is (-3, 0)

ii)  lies on y-axis with ordinate 5

  • It lies on y-axis, it has zero x-coordinate

I'd appreciate the help, its making my brain hurt plus i never was good at algebra
Andrei [34K]

Answer: I got -2

I plugged -6 in for y and then simplified. -6 x -6 = 36. 7 x -6 = -42. So 36 - 42 = -6. -6 + 4 = -2

In calm water, the motorboat of Jana is moving at the speed of 16.5km/h. On a river, because of the current, the boat moves fast
ki77a [65]

Answer: 707 km/h

Step-by-step explanation:

let c = speed of current

16.5 + c = speed of sailboat downstream

16.5 - c = speed of sailboat upstream

distance = travel time * speed

﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋

2(16.5 + c) = 5(16.5 - c)

33 + 2c = 82.5 - 5c

7c = 49.5

c = 7.07 km/h

What is the domain of g?
lawyer [7]

Answer:

A choice.

Step-by-step explanation:

Domain starts at x = - 7 and ends at x = 4. The domain from the graph is also continuous. Therefore, we can rule out C and D.

B is not correct as domain starts from x = -7 and not x = - 4.
