Answer:
Minimum value occurs at (x, y) = (-5,0)
Step-by-step explanation:
Given: 3x + y =15
Rewriting this equation to Slope - Intercept form, we get:
y = -3x + 15
Squaring both sides,


Substituting in
we get:

= 
Comparing this equation with
we get
and
.
The minimum value occurs at the axis of symmetry given by
.
Therefore, x = - 

If x = 5, y = -3(5) + 15 = 0
Thus, the point becomes (5,0) where it is minimum.
Answer 111
Step-by-step explanation:
Left 4. Or x-4 because the way it moves
Answer:
a = 2, b = - 6, c = 11
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
Compare the coefficients of the terms in standard form to
2x² - 6x + 11 = 0 ← in standard form
Thus a = 2, b = - 6 and c = 11
