5-2(n+2)greater than or equal to 4+n

Mathematics
1 answer:
wolverine [178]4 years ago
7 0

Answer and step-by-step explanation:

5-2(n+2)

we learn that: a*(b-c) = a*b - a*c so in this case:

5-2(n+2)

= 5 - 2n +(-4)

= 5 - 2n - 4

= 5 - 4 -2n

= 1-2n

When you compare 1-2n and 4+n

If n is a positive number (>0), 1-2n < 4+n

For example if n =3

1-6 compare with 4+3

-5 < 7

If n is a negative number (<0), 1-2n > 4+n

For example if n = -3

1 - 2*(-3) compare with 4 + (-3)

= 7 compare with 1

If n is 0 (n=0), 1-2n < 4+n

1-0 compare with 4+0

1 < 4

Hope this help you :3

What is the x value when g(x)=1 PLS HELP
olga_2 [115]

Answer:

I believe the answer is x=1.

Step-by-step explanation:

I am a bit confused on what is wanted, but g(x) is the x value on the line g. so when g(x)=1, I think x=1 on the line g.

Explain how you could use the work backward problem-solving strategy to solve the equation x/4-6=2
Slav-nsk [51]
Hey there, Nancykkxx00!

To solve the equation
x \div 4 - 6 = 2
In backward problem-solving strategy, you first need to, if there are no parenthesis, either add or subtract first from both sides.
Here we have a negative 6 ( -6 ), so since we are doing it backwards, instead of subtracting 6, we are adding 6 to both sides.
x  \div 4 - 6 + 6 = 2 + 6
x \div 4 = 8
( The six from the left side cancels out making it 0 )
Now we move to division. Since we are diving (we always have yo do the opposite of what we are doing), we need to multiply. So,
x \div 4 \times 4 = 8 \times 4
Always do it on both sides.
Now, we end up with
x = 32
If we plug it in, it will be like this
(32) \div 4 - 6 = 2
8 - 6 = 2
2  = 2

So, the answer is
x = 32

Thank you for using Brainly.

Please help me!! what were the errors​
spayn [35]

Answer:

see explanation

Step-by-step explanation:

Given

23x + xy - y + 3y + 5 - 20x + 6xy ← collect like terms

= (23x - 20x) + (xy + 6xy) + (- y + 3y) + 5

= 3x + 7xy + 2y + 5

He combined the coefficients of the x- term incorrectly

He combined the coefficients of the y- term incorrectly

He missed out the constant term ( + 5)
