Places a and b are 80 km apart from each other on a highway. a car starts from a and another from b at the same time. if they move in same direction they meet in 8hrs and if they move towards each other they meet in 1 hr 20mins . find the speed of cars (CLASS 10 MATHS: PAIR OF LINEAR EQUATIONS IN 2 VARIABLE)

i have no clue at all sorry

step-by-step explanation:

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
