Answer:
8
Step-by-step explanation:
(15-4x)+5
(15-4(3))+5
(15-12)+5
3+5=8
Answer:
Step-by-step explanation:
multiply x as a negative.
Example:
f(x) = 3x + 1
f(-x) = -1(3x) + 1
f(-x) = -3x + 1
12 x 14 = 168 sq ft
12 x 10 = 120 sq ft
8 x 12 = 96 sq ft
Total would be 384 sq ft of carpeting needed.
Answer:
63 1/4
Step-by-step explanation:
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
