Help me guys. I don’t get this one. Thank you

207

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

= [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = 37 and d = 34 - 37 = - 3 , thus

= [ (2 × 37) + (17 × - 3) ]

     = 9( 74 - 51)

     = 9 × 23

     = 207

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
