Answer:
see below (upper left)
Step-by-step explanation:
When the x-values are sequential, a linear function will have y-values that differ by the same amount.
The upper left table has y-values that differ by -2.
The upper right table has y-values that differ by 2, -6, 2. These values are not the same.
The lower left table has y-values that differ by -1, 5, -13. These values are not the same.
The lower right table has y-values that differ by 1, 3, 5. These values are not the same.*
__
The upper left table represents a linear function.
_____
* The <em>2nd</em> differences are a constant 2, so this table represents a <em>2nd</em>-degree polynomial.
Answer:
5p+2s=15.50
Step-by-step explanation:
let p equal the number of slices of pizza
let s equal the number of sodas
so 5p and 2s equal 15.50$
Answer:
vertex = (- 3, 1 )
Step-by-step explanation:
given a quadratic in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - ![\frac{b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2a%7D)
f(x) = x² + 6x + 10 ← is in standard form
with a = 1, b = 6 , then
x = -
= - 3
substitute x = - 3 into f(x) for corresponding y- coordinate
f(- 3) = (- 3)² + 6(- 3) + 10 = 9 - 18 + 10 = 1
vertex = (- 3, 1 )
The triangles are not similar
