Answer:
A
Step-by-step explanation:
The solution to a system of equations is the point of intersection of the 2 lines.
The lines intersect at (6, 9 ) ← solution
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
Step-by-step explanation:
The explanatory is the independent variable, or the variable that goes on the x-axis of a graph. Here, that could be time or political affiliation.
The response variable is the dependent variable, or the variable that goes on the y-axis of a graph. Here, that would be percent that have a positive view of capitalism/socialism.

Step-by-step explanation:
Your question is incomplete, as the equations or graph or table(s) were not given.
However, I'll give a general way of solving this.
Take for instance, the equations are:
To do this, we start by equating both equations.
i.e.
Collect Like Terms
Take LCM
Cross Multiply
Make x the subject
Substitute 3/4 for x in
Hence:
