Answer:
The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:
and not
Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.
I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.
Solving the equation
Using distribution
Add both sides
Add 12 both sides
Divide both sides by 5
(7, 3) is the answer I believe
Answer:
m= 2/17
Step-by-step explanation:
do the formula x1 and y1 and x2 and y2
x1, y1 x2, y2
(-11,15) (23,19)
when subtracting you ALWAYS START WITH YOUR Ys
19-15= 4
now subtract your Xs
23- (-11)= 34
now your answer is 4/34
but that's not the last step you can simplify it and make it smaller,
they both go into 2 so know divide both of then numbers by 2
and you should get 2/17
your final answer should be 2/17
Answer:
Step-by-step explanation:
By the Mean Value Theorem, there is at least one number, c, in the interval (1,6) such that
f'(c) = [f(6) - f(1)]/ (6 - 1)
So, f(6) - f(1) = 5f'(c).
Since 2 ≤ f'(c) ≤ 4, 10 ≤ 5f'(c) ≤ 20
So, f(6) - f(1) is between 10 and 20.
