Answer:

B) 72

Step-by-step explanation:

The n-th term of an arithmetic sequence An = a1 + (n - 1) d

Given :

a28 = 423/4 and d = 5/4

So

a28 = a1 + (28 - 1)5/4

Now plug in a28 = 423/4

423/4 = a1 + 27(5/4)

a1 = 423/4 - 27(5/4)

= 423/4 - 135/4

a1 = (423-135)/4

a1 = 288/4

a1 = 72

Thank you.

Solve the system of equations
insens350 [35]

Answer:

x = 3, y = 1 is the solution of the given system.

Step-by-step explanation:

Here, the given system of equations is:

y = -x  + 4   ...... (1)

y = x - 2     ..........  (2)

Now, to find the solution of the system, SUBSTITUTE the value of y from equation  (1) in to the equation (2). We get ,

y = x - 2   ⇒   -x  + 4  = x - 2  ( as from (1), y = -x + 4)

or,  -x -x = -2 -4

or, - 2 x = -6 ⇒   x = 6/2  = 3

or, x = 3

⇒  y = x - 2 = 3 - 2 = 1

⇒ y = 1

Hence, x = 3, y = 1 is the solution of the given system.
