Answer:
1
Step-by-step explanation:
AC = 5, ao AB = 2.
This means B = -1+2 = 1.
Answer:
(2, -5)
Step-by-step explanation:
Convert to vertex form:
3x^2 - 12x + 7
= 3(x^2 - 4x) + 7
Completing the square:
= 3[ (x - 2)^2 - 4)] + 7
= 3(x - 2)^2 - 12 + 7
= 3(x - 2)^2 - 5.
Comparing with the general form
a(x - b)^2 + c we see that the vertex is (b, c) = (2, -5).
-25/12
You have to change the denominator the the least common multiple then multiply the numerator by the number you multiplied it’s denominator with.
