That’s quadratic. Here’s how you can tell..
Linear:
Formula: y = mx + b
Example: y = 12x + 3
Appearance: A straight line
Quadratic:
Formula: y = ax^2 + bx + c
Example: y = 12x^2 + 2x + 5
Appearance: A parabola (U)
It says to simplify so number 3 would be 12
Number 4 is
Number 5 is
Answer:
(–3, –4)
Step-by-step explanation:
Given pair of linear equation
-4x+y = 8
=> y = 8 + 4x _____(1)
x - 5y = 17 (2)
substituting value of y from equation 1 in equation 2 we have
x - 5(8 + 4x) = 17
=> x - 5*8 -5*4x = 17
=> x - 40 - 20x = 17
=> -40 - 19x = 17
=> -19x = 17+40 = 57
=> x = 57/-19 = -3
Thus, x = -3
y = 8 + 4x = 8 +4(-3) = 8 -12 = -4
Thus, y = -4
Hence, paired solution for given equation is (–3, –4).
The simplified answer to this expression would be
