Solve the system by graphing.

3x+8y=16

3x+8y=-64

-3x-y=10

4x-4y=8

or

y = -3x - 10

P(0,-10) and P(-2, -4) on this line: Plot and connect with the Line.

y = x - 2

P(0, -2) and (2,0) on this line: Plot and connect with the Line.

P(-2,-4) is the ordered pair that is the solution for this system of EQs

On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines

Hope this helps!!!

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%
