Answer:
We see that:
The axis of symmetry is defined by this formula:
And replacing we got:
Thn the axis of symmetry would be X=-1
Step-by-step explanation:
For this case we have the following function:
If we compare this function with the general expression of a quadratic formula given by:
We see that:
The axis of symmetry is defined by this formula:
And replacing we got:
Thn the axis of symmetry would be X=-1
2b. Add then divide, so 9+8=17, then answer = 17/7 unless you have to write in improper faction.
3b. 5^3= 5 x 5 x 5
20/25 as a decimal is 0.8
If they give you the total price and the price after the discount you can use this "formula" to solve it p/100=b/a where p is the percentage, a is the total price and b is the price after the discount.
Answer:
I would put B
Sorry if it's wrong I would have to know what the test is about to answer this
