Y ≥ |x| + 3
(0) ≥ |-3| + 3
0 ≥ 0 (true)

y ≥ |x| + 3
(6) ≥ |-3| + 3
(6) ≥ 3 + 3
(6) ≥ 6 (true)

y ≥ |x| + 3
(4) ≥ |0| + 3
4 ≥ 0 + 3
4 ≥ 3 (true)

all of them are true, so it would be the last choice, or all of the above, or whatever the 4th choice is

hope this helps

y ≥ |x|+3

Replace x with the given x values and solve for y:

y≥ |-3| +3 = 3+3 = 6, not 0, so (-3,0) is not a solution.

(-3,6) is a solution

(0,4) is not a solution.

The answers are (-3,0) and (0,4)

In a 30° -60° -90° triangle, what is the length of the hypotenuse when the shorter leg is 7 in.?
soldi70 [24.7K]

Answer:

the length of the hypotenuse is 14 in

Step-by-step explanation:

Focus on the 30 degree angle.  Recall that the sine of an angle is defined as

             opposite side        

sin Ф = ----------------------

                hypotenuse  

and that sin 30° is always 1/2.

                                7 in                               1

Then sin 30° = ------------------- must equal -----      

                         hypotenuse                        2

After cross-multiplying this equation, we have 2(7 in) = (1)(hypotenuse),

so that the length of the hypotenuse is 14 in.

Is the following number rational or irrational? -3+π
enyata [817]

Answer:

B, irrational

Step-by-step explanation:

We know that π is irrational, since it can not be written as a division between  natural numbers (a sub class of Real numbers called N), it's value is 3,1415(a whole bunch of decimals after this)

If you remove the decimal part of π by subtracting the integer part of it, that is the number 3. the result will still being and irrational number

Since π= 3(the rational part) +0,1415... (the irrational part)

The resut of π-=3= 0,1415...
