Awnser is a is 8 b is 10 and c is 4
A function is called linear if highest degree of the equation is 1.
Here, degree of x and y is 1 hence it's a linear function.
0.4x + 0.28 = 0.6x - 4.2
0.4 x - 0.6x = - 4.2 - 0.28
- 0.2x = -4.48
x = 22.4
Answer:
Step-by-step explanation:
<u>Roots:</u>
<u>The equation:</u>
- (x - x₁)(x - x₂) = 0
- (x - (-3))(x - 5) = 0
- (x + 3)(x - 5) = 0
- x² + 3x - 5x - 15 = 0
- x² - 2x - 15 = 0
