<h3>Answer:</h3>
- g(x) = -18x +8
- y-intercept: (0, 8)
- domain: (-∞, ∞)
- range: (-∞, ∞)
<h3>Explanation:</h3>
Reflecting a function across the x-axis changes every y-value to its opposite. That is, f(x) = 18x becomes g(x) = -18x.
Shifting a function upward 8 units adds 8 to every y-value. That is, g(x) becomes g(x)+8.
The combined effect of these two transformations on f(x) is to give you ...
... g(x) = -18x + 8
You recognize this as the equation of a line in slope-intercept form, with the y-intercept being +8. That is, g(0) = -18·0 +8 = 8. The y-intercept is ...
... (0, 8)
The domain and range of any linear equation is "all real numbers," that is, ...
... (-∞, ∞).
Answer:
x = -1
Step-by-step explanation:
-3(x-1) + 9 = 15
-3x + 3 + 9 = 15
-3x = 3
x = -1
So if she got them at 30% off that means
$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%
original price was $90
