Answer:
Step-by-step explanation:
Let's start with function (x, y)
Transformations in the given order result in following
<u>A dilation by a factor of 4 with the origin as the center of dilation</u>
- This results in both coordinates multiplied by 4
- (x, y) → (4x, 4y)
<u>A reflection across the y-axis</u>
- This results in x-coordinate changing sign to opposite
- (4x, 4y) → (-4x, 4y)
<u>A 90° counterclockwise rotation about the origin</u>
- This results in x-coordinate swapping with negative y-coordinate
- (-4x, 4y) → (-4y, -4x)
<u>A translation 3 units down</u>
- This results in y-coordinate change by -3
- (-4y, -4x) → (-4y, 4x - 3)
<u>The final function is: </u>
Answer:
350 of the students are girls.
Step-by-step explanation:
5+7 = 12
600/12 = 50
50 x 7 = 350
Answer:
Step-by-step explanation:
Given
- f(x) = 2x
- g(x) = x² - 1
- (f - g)(x) = ?
Solution
- (f - g)(x) = 2x - (x² - 1) = 2x - x² + 1 = -x² + 2x +1
- (f - g)(x) = -x² + 2x +1
