Answer: C
Step-by-step explanation: I don't know if it's right or not
Answer:
Step-by-step explanation:
(x + 4)/2= 3
x + 4 = 6
x = 2
(y - 4)/2= 2
y - 4 = 4
y = 8
(2, 8) the other endpoint
1) Jane is (x - y) years old
2) Anna was (x - 3) years old 3 years ago
3) Jane will be (x - y + 5) years old in 5 years
4) The sum of their current ages is (2x - y) years
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).
Answer:
x = 7 (i think..)
Step-by-step explanation:
-3 (4 - 3x) = 5x + 16
* multiple -3 to each number in the parenthesis
-12 + 9x = 5x + 16
* add 12 to both sides to cancel it and combine like terms on the other side
9x = 5x + 28
* subtract 5x from both sides to cancel it out and combine like terms
4x = 28
* divide 4 from both sides to get x alone
x = 7
