Solve the equation 21=6-x-4x

Mathematics
1 answer:
Gemiola [76]4 years ago
6 0

Answer:

21 = 6 - <em>x</em> - 4<em>x</em>

simplify 6-x-4<em>x</em> to 6-5<em>x</em>

21 = 6-5<em>x</em>

subtract 6 from both sides

21-6 = -5<em>x</em>

simplify 21 - 6 to 15

15 = -5<em>x</em>

divide both sides by -5

\frac{-15}{5} = <em>x</em>

simplify \frac{15}{5}  to 3

-3 = <em>x</em>

switch sides

<em>x</em> = -3

The domain of: x+3 under square root
Gennadij [26K]

Answer:

All real numbers except where x<-3

Step-by-step explanation:

Values of x that make negatives under even radicals are not part of the domain. Any value of x that is less than -3 would make a negative under the square root, so those are not included in the domain.

What is the explicit rule for this sequence?<br> -5, 15, – 45, 135, ...
hoa [83]

Answer:

Step-by-step explanation:

In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

an = a1r^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the given sequence,

a1 = - 5

r = 15/- 5 = - 3

Therefore, the explicit rule for this sequence is

an = - 5(- 3)^n - 1

A scuba diver swam 96 feet beneath the surface of the lake . He then climbs up 49 feet. What is his depth now?
Iteru [2.4K]
If this question is as simple as it seems all you would have to do is subtract. If he is down 96 feet then goes up 49 feet you would do 96-49.

The answer is 47 feet.

I hope this helps! Let me know if this is right.
