How do I graph an inequality in one variable?

Mathematics

Masja [62]3 years ago

It depends on the variable.

If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).

Similarly for y, except it would be a horizontal line with either everything above or below shaded.

You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded

Answer:

n =7

Step-by-step explanation:

(n+1) +1 + (n-1) = value  first row

3+ (2n-9) +n = value   second row

The value has to be the same

Set the equations equal

(n+1) +1 + (n-1) =3+ (2n-9) +n

Combine like terms

2n+1 = 3n-6

Subtract 2n from each side

2n+1-1 -2n = 3n-6-2n

1 = n-6

Add 6 to each side

1+6 = n-6+6

7 = n

Jessica completed 21 math problems in 14 minutes. At this rate, how many math problems could she complete in 30 minutes?
harina [27]
To do this problem, you need to find how many questions per minute she can do. You would need to do 21 divided by 14. Which equals 1.5 questions per minute. From there you would do 1.5 times 30 and get 45.

So she can get 45 questions in 30 minutes.


Hope that helps!!

Jake has proved that a function, f(x), is a geometric sequence. How did he prove that?
Mashutka [201]

Answer:

He showed that f(n) ÷ f(n - 1) was a constant ratio.

Given that Jake has proved that a function f(x) is a geometric sequence.

GEOMETRIC SEQUENCE:  A geometric sequence is a sequence of numbers where each term is found by multiplying the preceding term by a constant called the common ratio, r.

So, in Jame's proof, he showed that each term is multiplied by a constant to get the next term.

That is, if 'c' is the constant that was used in the proof, then we must have

This implies that

Therefore, he showed that  f(n) ÷ f(n - 1) was a constant ratio.

A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is
VashaNatasha [74]
The answer is <span>10 units
</span>
The diameter of the cylinder (d) is the twice of its radius (r): d = 2r

The volume (V) of the cylinder with radius r and height h is:
V = π r² h

We have:
d = 2r
r = ?
h = 7
π = 3.14
V = 175π

175π = π * r² * 7
175 = r² * 7
r² = 175/7
r² = 25
r = √25
r = 5


d = 2r
d = 2 * 5
d = 10

What is the equation of the graphed line written in standard form?
liraira [26]

Answer:

The last one   5x-3y=15   This is the same as  y= (5/3)x -5

Step-by-step explanation:

5x-3y=15

Move 5x to the right (becoming negative)

-3y = -5x +15

Divide everything by - 3

y= (5/3)x -5

  

y intersect= -5   ( line crosses y coordinate at -5)

Slope = 5/3      From -5  you start counting  (5 up,3 right,5 up,3 right....  OR    5 down,3 left,5 down,3 left........)
