I think it is around 21. i rounded it to the nearest ones. the actual answer was 20.5533333333. hope this helped
Answer:
Step-by-step explanation:
Solving for k:
Subtracting 16 from both sides.
Dividing both sides by 3.
Solving for x:
Flipping the original equation.
Subtracting 9 from both sides.
Dividing both sides by 6.
Answer:
70
Step-by-step explanation:
7^2 - ( 6-3^3)
PEMDAS
Parentheses first
7^2 - ( 6-3^3)
The exponent in the parentheses first
7^2 - ( 6-27)
7^2 - ( -21)
Now the exponent
49 - (-21)
Now subtract
49 +21
70
It would be the first graph
That is because the 2nd and 3rd graphs start at a point close to (0,-2) but it is not the correct point.
Now using (0,0) as a solution plug it in for the x and y values like so
0 <−3(0)−2 = 0 < -2
0 ≤ 0 −2 = 0 ≤ -2
This does not work so solutions from (0,0) up cannot be solutions, so the first graph must be the right answer.
