Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)
Answer:
1) 2/3, two triangle segments
2) 1/7, one triangle segment
3) 3/9, three triangle segments left
really, you could do this by subtracting the top number, the numerator, because these visual diagrams have the same bottom number, or denominator, but for now, just subtract the segments. hope this helps, good luck.
Answer:
150/50=3
Step-by-step explanation:
she drove 150
Each hour she drove she went 50 miles
we know that if we miltiply 50 x 3 it will equal 150 which is the total distance.
you can also reverse multiplication 50x3=150 or 150/50=3
