Answer:
B.
Step-by-step explanation:
First, let's start from the parent function. The parent function is:
The possible transformations are so:
,
where a is the vertical stretch, b is the horizontal stretch, c is the horizontal shift and d is the vertical shift.
From the given equation, we can see that a=1 (so no change), b=3, c=-3 (<em>negative </em>3), and d=3.
Thus, this is a horizontal stretch by a factor of 3, a shift of 3 to the <em>left </em>(because it's negative), and a vertical shift of 3 upwards (because it's positive).
Answer:
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let w = wooden block
Let p = plastic bricks
<u>Given the following data;</u>
Price of wooden block per pounds = $5
Price of plastic brick per pounds = $10
*Translating the word problem into an algebraic equation*
For the 10-pound mixture;
.........equation 1
For the $80 mixture;
..........equation 2
Solving the linear equation by using the substitution method;
Making w the subject in equation 1:
.......equation 3
Substituting "w" into equation 2;
Simplifying the equation, we have;
Rearranging the equation, we have;
p = 6 pounds (For the plastic brick).
To find w;
Substituting "p" into equation 3;
w = 4 pounds (For the wooden block).
