Answer:
x=6 is not a solution
Step-by-step explanation:
We can substitute 6 as x to find out:
5(6-3)=6+13
first, because of PEMDAS we'll do 6-3
5(3)=6+13
multiply 5 by 3 and add 6 and 13
15=19
Since the statement is not true, that means that x=6 is not a solution
Hope this helps!
You do the sum backwards,
36-16=17
17x3=51
Then you check it to make sure,
51/3=17
17+19=36
:) hope this hepled x
Answer:
It goes up by 2.5
Step-by-step explanation:
Mean equation: (n₁ + n₂ + n₃ + ...)/n
Current mean: (2 + 4 + 7 + 6 + 3 + 6 + 7)/7 = 35/7 =<em> 5</em>
New mean: (2 + 4 + 7 + 6 + 3 + 6 + 7 + 25)/8 = 60/8 = <em>7.5</em>
Difference: 7.5 - 5 = 2.5
Please see the attached graph to see f(x) = (x - 3) ^2 +5 graphed.
