Answer:

Domain: all real values of x except -2

Range: y > -4

Step-by-step explanation:

Domain: union of all intervals of x

x < -2 U -2 < x < 0 U x》0

This includes all real values of x except x = -2

When x < -2

-x - 2 > 0

When -2 < x < 0

-4 < -x² < 0

When x》0

x》0

Range is the union of all these outputs

y > 0 U -4 < y < 0 U y》0

y > -4

Answers and Step-by-step explanations:

Notice that -2 is not included in the inequality, but any other number is. That means that the domain is all real numbers except x = -2.

For the range, I recommend you draw a graph (see the attachment).

As can be seen, the range will be y > -4.

Hope this helps!

Cone A has a diameter of 12 meters and a slant height of 9 meters. The linear dimensions of cone B are 5 times the linear dimens

Karolina [17]

Answer:

Cone volume formula

To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3: volume = (1/3) * π * r² * h

Can somebody please help me

Here is your answer

B. (12,30)

REASON:

Given,

$y= 2x+6$ .......(i)

$3x-y= 6$ .......(ii)

Putting the value of y from eq.i in eq.ii we get

$3x-(2x+6)=6$

$3x-2x-6=6$

$=6+6$

$x=12$

Putting x=12 in eq.i we get

$y= 2x+6$

$y= 2×12+6$

$y= 24+6$

$y= 30$

So,

$\bold{x=12 and y= 30}$

Hence answer is (12,30) in which x=12 and y=30

A caterpillar crawling in a straight line across a coordinate plane starts at point (-3,

Irina18 [472]

9514 1404 393

Answer:

Step-by-step explanation:

In vector form, the equation of point p on the line can be written as ...

p = (-3, -4) +t(25 -(-3), 38 -(-4)) . . . . . for some scalar t

p = (-3, -4) +t(28, 42)

p = (-3, -4) +14t(2, 3)

where t takes on any value between 0 and 1.

If we let t = n/14 for some integer 0 ≤ n ≤ 14, then the coordinates of point p will be integers.

There are 15 values that n can have in the allowed range.

The caterpillar touches 15 points with integer coordinates.
