Answer:
24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is
, you already have the
and another side which can be
or
.
Because you have the hypotenuse and a side , your equation looks like this now:
and when you solve for be you just subtract
to get 24.

y = -3x - 9
------------------------------------------------------------------------------------------
Option 1
------------------------------------------------------------------------------------------
If I substitute x = -9, I should get y = 0
When x = -9
y = -3 (-9) - 9
= 18 (I did not get 0, wrong)
------------------------------------------------------------------------------------------
Option 2
------------------------------------------------------------------------------------------
If I substitute x = -3, I should get y = 0
y = -3(-3) - 9
y = 9 - 9
y = 0 (Yes, I got 0, correct)
------------------------------------------------------------------------------------------
Option 3
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -3
y = -3 (0) - 9
y = 0 - 9
y = -9 (I did not get -3, wrong)
------------------------------------------------------------------------------------------
Option 4
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -9
y = -3 (0) - 9
y = 0 - 9
y = -9 (Yes, I got -9, correct)
------------------------------------------------------------------------------------------
Answer: (-3, 0) and (0, 9) are ordered pairs of the equation (Answer B, D)

C=(-10;5). If you want an explanation I would be happy to explain it
Subtract the blue caps:
25-11 = 14 caps are either white or green.
Let green = X
white = X +2
Green + white = 14:
x + x +2 = 14
Combine like terms:
2x +2 = 14
Subtract 2 from both sides:
2x = 12
Divide both sides by 2:
x = 6
There are 11 blue caps, 6 green caps and 8 white caps.
44
Step-by-step explanation:
The line is pointing to 44 and the small lines are counting by two
