These are the four statements that come with the question and from which you have to select the right one.

A) −1=3(−13)−10
     −1=−2(−13)−15

B) 13=3(1)−10
     13=−2(1)−15

C) 1=3(13)−10
     1=−2(13)−15

D)  −13=3(−1)−10
     −13=−2(−1)−15

The answer is the option D.

Just replace the values x = -1 and y = - 13 in the two equations and you obtain the answer:

1) y = 3x - 10 => - 13 = 3(-1) - 10
2) y = -2x - 15 => -13 = -2(-1) - 15

Find the measure of arc DF (with an explanation of how to solve please!)
allochka39001 [22]

Answer:

mDF = 90°

(Assuming arc mCE is 5x + 10)

Step-by-step explanation:

When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.

So in this case, we have:

70° = (mCE + mDF)/2

Assuming mCE is 5x + 10, we have:

70 = (5x + 10 + 11x + 2)/2

70 = (16x + 12)/2

70 = 8x + 6

8x = 64

x = 8

So the arc mDF is:

mDF = 11x + 2 = 11 * 8 + 2 = 90°

If Rahul walks 9km in a week and Vansh walks 900 m daily, which of these is true about the distances they cover in a week?
pantera1 [17]

Answer: Rahul walks 2.7 km more than Vansh.

Step-by-step explanation:

The options include:

a. Vansh walks 7.2 km more than Rahul.

b. Vansh walks 2 km more than Rahul.

c. Rahul and Vansh both cover the same distance.

d. Rahul walks 2.7 km more than Vansh.​

Distance covered by Rahul weekly = 9km

Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km

From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.

Note: 1000 meters = 1 kilometers
