x + y = 36 ....(1)

And,

xy = 315 .....(2)

We know that,

⇒

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

Adding (1) and (3), we get

x + x = 36 + 6 ⇒ 2x = 42

⇒ x = 21

Putting the value of x in (1), we get

21 + y = 36

⇒ y = 36 -21 = 15

Hence, the numbers are 21 and 15.

Lo siento, no hago matemáticas por favor hazlo tú mismo. En caso de que no traduzcas esto voy a poner un par de números. 34 es el número para hacer que alguien que habla inglés esto es legítimo. 45 = 28 + x28. Te quiero

Which of the following inequalities is graphed on the coordinate plane

azamat

Answer:

The answer is D.

Step-by-step explanation:

Well, all the equations are the same except for the symbol so you don't need to figure out the equation of the line.

Anyways, note that the line is dotted, which means it cannot be A nor B since they have an "equal to."

Also, note that the shaded region is above the graph. Since it is above, it means that y is greater than whatever x is.

Thus, the answer is D.

Answer:

B. $x^{2} +2x-8$

Step-by-step explanation:

Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.

Now substitute x=-4 in all the options

A. $x^{2} -2x-8$

16+8-8=16>0

so out of option A and C option C is correct.

B. $x^{2} +2x-8$

16-8-8=0 which means for the values of x>-4 $x^{2} +2x-8$ is less than 0

Now substitute x=2 in all the options

A. $x^{2} -2x-8$

4-4-8=-8<0 . so option A and C both are incorrect.

B. $x^{2} +2x-8$

4+4-8=0 which means for the values of x<2 $x^{2} +2x-8$ is less than 0

Therefore the correct option is B
