Remove the brackets on the left
10 - 9x + 120 = - 9x You get a bizarre result no matter what you try to do to resolve this. If you say any number will do pick, a number at random for x. Say 10

10 - 90 + 120 = -90 Is this statement true? No. You only need 1 exception but 0 is a popular number to look for answers. Will it work?
10 - 0 + 120 = 0 That doesn't work either.

There is no number you could pick that that would give you anything but 10 + 120 = 0

B <<<<<< No Solution

Pls answer the question with explanation
adell [148]

Answer:

a) 96m

b) 2 m/s^2

Step-by-step explanation:

The distance travelled in a velocity time graph as shown in the image is the area of the shape. As such, considering the first 14 seconds, the distance covered will be computed by finding the area of the shape.

Note that the shape to be considered ends t the 14 seconds mark. This shape is a trapezium. The area of  a trapezium is given as

A = 1/2(a + b) h

where a and b are the parallel sides of the trapezium and h is the height As such, the distance covered in the first 14 seconds

= 1/2 (14 + 10) * 8

= 4 * 24

= 96m

The acceleration after 4 seconds

Acceleration is the rate of change of velocity with time, at time 0 second, the velocity is also 0 but at time 4 seconds, the velocity is 8 m/s hence, the acceleration after 4 seconds

= 8/4

= 2 m/s^2

What is the mode?<br> What is the median?<br> What is the range?
Marina CMI [18]

<h2>ANSWER : </h2>

<h2><<< In this case, the mode is 9 seconds. The median is the middle number in a list of numbers ordered from smallest to largest. so 10 is the median of this set of results. The range is the difference between the lowest value and the highest value, so the range here is 15 - 9 = 6. </h2>
