Answer:
Explanation:
Given function: f(x) = -2x² - 3x + 20
To find the x-intercepts of a function, f(x) = 0
=================
-2x² - 3x + 20 = f(x)
-2x² - 3x + 20 = 0
-2x² - 8x + 5x + 20 = 0
-2x(x + 4) + 5(x + 4) = 0
(-2x + 5) (x + 4) = 0
-2x + 5 = 0, x + 4 = 0
-2x = -5, x = -4
x = -5/-2,x = -4
x = 5/2, x= -4
Coordinates: (-4, 0), (5/2, 0)
Given:
The inequality is:
To find:
The graph of the given inequality.
Solution:
We have,
Subtract both sides by 1.
Divide both sides by 3.
The value of t is less than or equal to .
Since , it means
is included in the solution, therefore there is a closed circle at
and an arrow approaches to left from
.
Therefore, the correct option is A.
Answer:
<h3>X=16</h3>Step-by-step explanation:
Add 24 to both sides
24x/24=384/24
hope it helps!!
