0 = 2x^2 + 5x -3
0 = (2x-1)*(x+3)
2x-1=0 and x+3=0
X= 1/2 and x = -3
Y= 2(0)^2 + 5(0) - 3
Y = -3
Answer:
The mean is 8.3.
Step-by-step explanation:
The simplified algebraic expression for the model is x = -1
<h3>What are algebraic expressions?</h3>
Algebraic expressions are known as mathematical statements gotten when operations such as addition, subtraction, multiplication, division, etc. are operated or used on variables and constants
From the figure given;
We have:
Now, let's add the variables
= x + x - x
= 2x - x
= x
For the constants
= -1^6 = -1
= 1 ^5 = 1
= 1 × -1 = -1
Thus, the simplified algebraic expression for the model is x = -1
