Answer:
17/15
Step-by-step explanation:
Find the GCF of the denominators
15
Convert the fractions
1/3 ---> 5/15
4/5 ---> 12/15
Add.
12/15 + 5/15 = 17/15
x=4.80989686
by simplifying both sides of the equation, then isolating the variable.
it is a because it is the line is in the spot we're it is ststop to go
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).
So for order of operations you start inside the parentheses and in order to add the insides you will need a common denominator which would be 15 on the bottom. So for 2/5 it would be 6/15 and for 11/3 would be 55/15 and then added together it would be 61/15. so then you would multiply and get 15(61/15). the 15 in the numerator will cancel with the denominator leaving only 61 and then the final step would be adding the 3 to 61 and the final answer will be 64
