Answer:
30
Step-by-step explanation:
V=lwh
V=2*3*5
V=6*5
V=30
4x-7: "seven less than" means you're going to subtract it from the upcoming value, which is "the product of four and a number". "a number" refers to an unknown variable, which I chose to be x. So put it all together and you get 4x-7
Answer: $36.3
Step-by-step explanation:
Since Christopher bought 3 toy trucks that costs $14.25 each. Then, the cost of the three toys will be:
= 3 × $14.25
= $42.75
Then, if he used a coupon for 15% off of the total purchase, then the final purchase will be:
= $42.75 - (15% × $42.75)
= $42.75 - (0.15 × $42.75)
= $42.75 - $6.4125
= $36.3375
= $36.3

Answer:
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
Step-by-step explanation:
Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.
Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).
<h3>Application</h3>
We observe that f(x) has been transformed by ...
- multiplying by -1 to get -f(x)
- replacing x with (x -2) to get -f(x -2)
- adding -3 to the function value to get -f(x -2) -3
The effect of these transformations is (correspondingly) ...
- reflection over the x-axis
- translate right 2 units
- translate down 3 units

The attached graph shows a function f(x) (red) and the transformed function (blue).
