And pick one of the pictures

which graph most likely shows a system of equations with one solution
a. first pic
b. second pic
c. third pic
d. fourth pic

c.third pic

Step-by-step explanation:

In the given figures we have a parabola and a straight line. The line is touching the parabola at two points ,no point,one point and two points in the first ,second ,third and fourth figure respectively.

For the system of equations with one solution the two equations will touch at one point.

In the third graph the red line is touching the parabola at one point and hence represent a system of equations having one solution.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
