Which ordered pair is not a solution of f(x)= 2x + 9?

what you do is subsitute the first number in the pair for x and subsitute the second number for f(x) you must have made a typing error when typing the options since they are alll correct proabably one of the two (7,23) is mistyped basically one example is the point (0,9) x=0 f(x)=9 subsitute 9=2(0)+9 9=0+9 9=9 this is true so it is a soltuion the answer choice is not listed (probably because of a typo)

(3, 14)

Step-by-step explanation:

To find the order which is a solution,we will need to check;

f(x) = 2x + 9

(0, 9)

x = 0

we replace x by 0 in the equation

f(0) = 2(0) + 9

9 = 9

Therefore ( 0, 9) is a solution of the function

we check the next pair (7, 23)

f(7) = 2(7) + 9 = 14+9=23

23 = 23

(7, 23) is a solution to the function

we move to the next pair

(3, 14)

f(3) = 2(3) + 9

= 6 + 9

= 15

14 = 15

since 14 is not equal to 15

Therefore (3, 14) is not a solution to te function

Simple trigonometry.

Imagine a triangle, 30⁰ at the boat, with the hypotenuse being 600ft, and the adjacent being parallel to the water; we need to work out the height, or the opposite.

We use sin(), which is opposite over hypotenuse, as we know the hypotenuse and we want to find out the opposite.

We do

600 * sin(30) = 300ft
