Answer:
x = 23
Step-by-step explanation:
Δ ABC and Δ DEF are congruent by the SAS postulate, thus corresponding sides are congruent, that is
BC = EF, substitute values
x - 4 = 19 ( add 4 to both sides )
x = 23
when is removed from the expression derived by the mean value theorem.
Let be , for , according to the mean value theorem, also known as Rolle theorem, there is a value so that:
(1)
Where:
- First derivative evaluated at .
- Function evaluated at zero.
Then, we simplify the expression below:
Please that is equalized to because of . If we eliminate , then we find that .

Answer:
k=5
Step-by-step explanation:
for every one unit on the x, the y goes up five. So, the ratio is 5:1 or five.
She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8
