yylt;3x+4lt;5x+2Which of the following ordered pairs (x,y) satisfies the system of inequalities?Choose 1 answer:(A) (−1,0)(B) (1,7)(C) (2,11)(D) (3,−4)
Q. y<3x+4y<5x+2Which of the following ordered pairs (x,y) satisfies the system of inequalities?Choose 1 answer:(A) (−1,0)(B) (1,7)(C) (2,11)(D) (3,−4)
Test (−1,0) in 1st inequality: Test the ordered pair (−1,0) in the first inequality y < 3x+4. Substitute −1 for x and 0 for y. 0 < 3(-1) + 4 0 < -3 + 4 0 < 1 Since 0 < 1 is true, (−1,0) satisfies the first inequality.
Test (−1,0) in 2nd inequality: Test the ordered pair (−1,0) in the second inequality y < 5x+2. Substitute −1 for x and 0 for y. 0 < 5(-1) + 2 0 < -5 + 2 0 < -3 Since 0 < -3 is false, (−1,0) does not satisfy the second inequality.
Test (1,7) in 1st inequality: Test the ordered pair (1,7) in the first inequality y < 3x+4. Substitute 1 for x and 7 for y. 7 < 3(1) + 4 7 < 3 + 4 7 < 7 Since 7 < 7 is false (7 is not less than 7), (1,7) does not satisfy the first inequality.
Move to next pair: Since (1,7) does not satisfy the first inequality, there is no need to test it in the second inequality. We can move on to the next ordered pair.
Test (2,11) in 1st inequality: Test the ordered pair (2,11) in the first inequality y < 3x+4. Substitute 2 for x and 11 for y. 11 < 3(2) + 4 11 < 6 + 4 11 < 10 Since 11 < 10 is false, (2,11) does not satisfy the first inequality.
Move to next pair: Since (2,11) does not satisfy the first inequality, there is no need to test it in the second inequality. We can move on to the next ordered pair.
Test (3,−4) in 1st inequality: Test the ordered pair (3,−4) in the first inequality y < 3x+4.Substitute 3 for x and −4 for y.-4 < 3(3) + 4-4 < 9 + 4-4 < 13Since -4 < 13 is true, (3,−4) satisfies the first inequality.
Test (3,−4) in 2nd inequality: Test the ordered pair (3,−4) in the second inequality y < 5x+2. Substitute 3 for x and −4 for y. -4 < 5(3) + 2 -4 < 15 + 2 -4 < 17 Since -4 < 17 is true, (3,−4) satisfies the second inequality.
Solution found: Since the ordered pair (3,−4) satisfies both inequalities, it is the solution to the system of inequalities.
