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
Answer:
1300
Step-by-step explanation:
Given that :
Number of sections = 8
Number of seats per section, x ;
150 ≤ x ≤ 200
The possible Number of seats in the auditorium :
Number of seats per section * number of sections
150 * 8 ≤ x ≤ 200 * 8
1200 ≤ x ≤ 1600
The possible Number of seats will lie within 1200 and 1600
From the options, only 1300 lie within this range

Step-by-step explanation:
Answer:
x + (5x-9)
Step-by-step explanation:
x stands for the number of coins Nancy has
Kevin has 9 less than 5 times what Nancy has, so his part of the expression is 5x-9
To find the total number of coins they have, you have to add Nancy's number of coins x plus Kevin's number of coins 5x-9
x + (5x-9)
But you have to put parentheses around Kevin's 5x-9 so that part of the expression is calculated first, as per order of operations
