Answer:
X= 2/5 y=-2
Step-by-step explanation:
5x + 2y = -2
3x - 5y = 11.2
Using the elimination method
Multiply equation 1 by 3
Multiply equation 2 by 5
15x + 6y = -6
15x - 25y = 56
Subtrat 3 from 4
-31y= 62
Divide both sides by -31
y= -2
To arrive at x, substitute y= -2 in equation 1
5x + 2y = -2
5x + 2(-2)= -2
5x -4 = -2
Collect like terms
5x= -2+4
5x= 2
Divide both sides by 5
x= 2/5
Answer:
I believe it is y = -3x + 2

Answer:
The value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
Step-by-step explanation:
Given
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
To determine
f(x) - g(x)
Using the formula
f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)
= 3x² + x - 3 - x² + 5x - 1
= 2x² + 6x - 4
Therefore, the value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
