Which system of inequalities is graphed below?

b is your answer

hope i helped

Option A is the answer.

Step-by-step explanation:

Parent function of the given parabola is y = x² which passes through origin (0,0).

If we convert this function in the form of inequality y > x² then the outlines of the graph will be dotted and shaded part will be inside the parabola upwards.

Now we shift this parabola 2 unit upwards on y axis then inequality becomes y > x² + 2 ( shaded in orange color )

when we shift the parent function 6 units downwards then inequality formed will be y > x² - 6 as shown in other color.

Therefore, system of inequalities are y > x² + 2 and y > x²- 6

Option A is the answer.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
