Which ordered pair is not a solution of 1x) = 2x+9?
(7,23)
(3, 14)
(2, 13)
(0.9)

Just plug the coordinates into the equation; f(x) will be the y coordinate whereas x will be the x coordinate

In this case the answer is (3,14)

Proof: 14=2(3)+9

           14=6+9

           14≠15

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
