Answer:
The solutions are and .
Step-by-step explanation:
We have the following equation:
.
The first step to solve this problem is using
We replace in the equation 1, find the values of y, and then we replace in equation 2) to find the values of x.
To solve the equations, it is important to know how we find the roots of a second order polynomial.
Given a second order polynomial expressed by the following equation:
This polynomial has roots such that , given by the following formulas:
In this problem, we have
So
So:
The values of y are
We also have that:
So
And
There is no real solution for this. So our only solutions are and .
Answer:
third option
Step-by-step explanation:
In a linear relationship, the y variable is the dependent variable (meaning that it depends on the independent variable) and the x variable is the independent variable. Basically, y depends on x, and since in this case, by looking at the graph, we know that y is the total price and x is the number of pounds of tomatoes, the answer is the total price depends on the number of pounds.

If you substitute the -8 in for y you will get -72
You can then add the 72 to the other side and get -8x=64
Dividing by -8 to both sides to get x alone will give you x
X=-8
D) 40% 2/5=40 so 40 percent chance
