Answer:
18a+9
Step-by-step explanation:
Use the distribution property to expand the expression to:
9*(2a) + 9(1) = 18a + 9
Answer:
f(x) = - 2(x - 3)² + 2
Step-by-step explanation:
Given
f(x) = - 2x² + 12x - 16 ( factor out - 2 from the first 2 terms )
= - 2(x² - 6x) - 16
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² - 6x
f(x) = - 2(x² + 2(- 3)x + 9 - 9) - 16
= - 2(x - 3)² + 18 - 16
= - 2(x - 3)² + 2
Given:
The two points on the graph.
To find:
The distance between the two points in simplest radical form.
Solution:
From the given graph, it is clear that the two points on the graph are (-9,3) and (-3,-2).
Distance formula:

Using the distance formula, the distance between two points (-9,3) and (-3,-2) is:



On further simplification, we get


Therefore, the distance between the given points is
units.
Seventeen-thousand and one hundred 6 thousandths written in standard form would be 17,000.106
