Mathematics
1 answer:
kow [346]3 years ago
7 0

The sequence is

740, 707.60,675.20,642.80,...

Here first term is 740, and common difference, d is

707.60-740 = -32.40

Now we use the formula of nth term, which is

a_{n} = a+(n-1)d

Substituting the values of a,n and d, we will get

=740+(n-1)(-32.40), 23 months

Correct option is the second option .

If x-y=1 and xy= 56 then find the value of x+y​
tester [92]

Answer:

x + y = ±15

Step-by-step explanation:

Step 1: Write out systems of equations

x - y = 1

xy = 56

Step 2: Rearrange 1st equation

x = y + 1

Step 3: Substitution

(y + 1)y = 56

Step 4: Distribute

y² + y = 56

Step 5: Solve for <em>y</em>

y² + y - 56 = 0

(y - 7)(y + 8) = 0

y = -8, 7

Step 6: Plug in <em>y </em>to find <em>x</em>

x - 7 = 1

x = 8

x - (-8) = 1

x + 8 = 1

x = -7

Step 7: Find answer

x + y = ?

8 + 7 = 15

-7 + -8 = -15

So both 15 and -15 could be the answer.
