F(x)=-4x - 5 g(x)=3x - 2 Find( f - g )(x)

2 answers:

5 0

The way to solve this is simple subtraction of like terms after dealing with the negative.
-4x-5-(3x-2)
flip the signs associated with the negative (which is technically a -1)

-4x-5+3x+2
-4x + 3x = -1x=-x
-5+2= -3

-x-3

The number can be divided by the least common multiple of 3 and 5

kondaur [170]

9514 1404 393

Answer:

255

Step-by-step explanation:

If the sum of digits is 12, the number is divisible by 3. If the number ends in 0 or 5, it is divisible by 5. So, we're looking for ...

2x0 . . . where x is a digit and 2+x+0 = 12 . . . . . . not possible

2x5 . . . where x is a digit and 2+x+5 = 12 . . . . true for x=5

The number is 255.

Find the product (x-y)(6x+4y)

Mazyrski [523]

The product means you multiply, so:
-y × 6x = -6xy
-y × 4y = -4y²

x × 6x = 6x²
x × 4y = 4xy

= -2xy - 4y² + 6x

I hope this helps!

J. Reexamine the sequence 20, 14, 8, 2, ... from the problem

DENIUS [597]

Answer:

The n th of the given sequence is $t_{n} = 26-6 n$

Step-by-step explanation:

<u>Step 1</u> :-

Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.

given first term is 20 and difference is $d = second term- first term = 14-20=-6$

now the nth term of given sequence is

by using formula $t_{n}=a+(n-1)d$

$t_{n}= 20+(n-1)(-6)$

$t_{n}= 20-6 n+6$

final answer:-

$t_{n} = 26-6 n$

<u>verification</u>:-

$t_{n} = 26-6 n$

put n=1 we get first term is 20

put n=2 we get second term is 14

put n=3 we get third term is 8

put n=4 we get fourth term is 2

so the n th term of sequence is

$t_{n} = 26-6 n$
