Answer: Ayshab's average speed for the whole journey =
Step-by-step explanation:
Formula: Speed =
i.e. Time =
If Ayshab walked x miles at 4 mph, then time taken by him = hours
If she then walked 2x miles at 3 mph, then time for this period = hours
Average speed =
Hence, Ayshab's average speed for the whole journey =
Z = ax / y
A = 2
X = 28
Y = 14
Plug it into the formula then solve for Z.
Z = ax / y
Z = 2(28) / 14
Z = 56 / 14
Z = 4
Therefore, she should buy 4 boxes.
Answer:
C. 6 units
Step-by-step explanation:
It is a translation, so the length of the sides are not being affected since the entire shape is being moved.
The correct answer is x = 2 and x = -4.
In order to solve for this, you first need to plug in the f(x) value and solve for the absolute value statement.
f(x) = -5|x + 1| + 3
-12 = -5|x + 1| + 3 ---> subtract 3 from both sides.
-15 = -5|x + 1|----> divide both sides by -5.
3 = |x + 1|
Now that we have solved for the absolute value portion, we need to solve this equation twice. Once removing the absolute value and solving and the other by removing it and making the 3 negative. This is because even if the inside of the markers was -3, it would give us a 3 answer.
3 = x + 1
2 = x
Then the negative version.
-3 = x + 1
-4 = x
And there are your two answers.

The dashed line shows the graph of the function
This function has a maximum value of 1, a minimum value of -1, and a center value of 0.
a)
Graph G shows the same function but translated by 2 units up, thus the equation of G is:
b) The coordinates of P correspond to the value of
The value of G is
Since
The coordinates of P are
