Can u please answer this question

Answers

One Way:
We can change the mixed number to a decimal for comparing.

1(1)/(4) m = (5)/(4) m = 1.25 m

1.4 m     >    1.25 m
Darren   >     Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

1(1)/(4)(5)/(4) (Luke)
1.4 = (7)/(5)                               (Darren)
We need a common denominator to compare
(5*5)/(4*5)       (Luke)
(7*4)/(5*4)       (Darren)
(25)/(20)          (Luke)
(28)/(20)          (Darren)

(28)/(20)  >   (25)/(20)
        Darren           >            Luke
  
By:
(28)/(20)(25)/(20)(3)/(20)
Which is also by 0.15 m
Darren jumps higher and by 0.15 m

Which ordered pair does NOT lie on the graph of h(x )= -2x + 7I have no idea how to solve this, please help me! Thanks!

Answers

Replace X with the x value in the parenthesis and solve. If the answer equals the Y value inside the parenthesis, it is a solution.


A) (-2, 3), -2(-2) +7 = 4+7 = 11. 11 does not equal 3 so this is not a solution.

B) (-1,9), -2(-1) +7 = 2+7 = 9. 9 equals 9, this is a solution.

c) (3,1), -2(3)+7 = -6+7 = 1, 1 equals 1, this is a solution.

d) (4,-1) = -2(4) +7 = -8 +7 = -1. -1 equals -1, so this is a solution.


The only one that isn't a solution is A.
