What is the relation between distance travelled by a train and its speed, when time is constant? (a) direct
(b) indirect
(c) cannot be determined
(d) not related​

direct relation between distance travelled by a train and its speed, when time is constant.

Step-by-step explanation:

We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :

Where

d is distance

t is time taken

It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
