Identify the vertex and axis symmetry of the graph y=-2(x+1)^2+5

1 answer:

5 0

<span>y=2(x+1)^2-5.
axis of symmetry is x+1=0...or....x=-1...then y=-5 .hence vertex is (-1,-5)
y =-5 for x=-1 is the minimum value .hence direction of opening is upwards for the curve.</span>

The sum of two consecutive positive even integers is at most 14. List all possible pairs of integers.

anastassius [24]

Let X be the first number
there is a 2 numbers distance between each even number eg.2 ,4, 6, 8, etc.
So the 2nd number is X+2
The sum of the 1st and 2nd numbers = 14
X + X+2 =14
2X +2 =14
2X = 14-2
2X = 12
X = 12/2
X = 6
Therefore,
The first number i.e, X = 6
And the second number i.e, X+2 = 6+2 =8
******************************************************************************
This is the only positive pair in case of two consecutive numbers if the are even numbers but not consecutive there will be more pairs
12 + 2 = 14
10 + 4 = 14
8 + 6 = 14 (Already found)

Tom opens a bank account and makes an initial deposit of $500. The banker tells Tom that he is going to revive an annual rate of

daser333 [38]

So for this you will be using an exponential equation, which is $y=ab^x$ with a=initial value, b=growth/decay, y = total balance, and x = # of years

In this case, a = 500, and since with this problem the initial value is growing, you will add 100% to 6% to get 106%, or 1.06. The equation will be formed as such: $y=500(1.06)^x$
