Undefined slopes are when x equals a certain number.
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
From the given choices, B is the correct answer.
A has a slope of 0, so <em>m</em> = 0 and would become a horizontal line.
C has a negative slope, so it is not undefined.
D has a positive slope, so it is not undefined.
B shows a vertical line, and so it has an undefined slope.
Answer:
Rewrite the equation as

Answer:
(2, -5)
Step-by-step explanation:
g(x) = 3x² − 12x + 7
Complete the square.
g(x) = 3 (x² − 4x) + 7
g(x) = 3 (x² − 4x + 4) + 7 − 3(4)
g(x) = 3 (x − 2)² + 7 − 12
g(x) = 3 (x − 2)² − 5
The vertex is at (2, -5).
For easier, let's say x represents a pack of 10 and y represents a pack of 30
we can start with 2 of the 30's
2y=60
we can replace one of the 30's with 3 of the 10's
y+3x=60
and finally we can use all 10's
6x=60
there are only 3 ways
Alright,
10 x 2 = 20
2 x 3.7 = 7.4
7.4 + 20 = 27.4
When you would round this number, it would go to around 27.
