Answer:

Hi, this question is a little unclear.  If you want to know what percentage he saved, it would be 30%, and to convert that percentage into a decimal would be a decimal of 0.30

Answer:

$70.00

Step-by-step explanation:

Add .00 to the end of each amount.

Make sure that the decimal points are lined up like a straight line.

Subtract 100.00 - 30.00

You should receive 70.00 and don't forget the dollar sign at the end so the answer is $70.00.

1. Addition
nexus9112 [7]

Answer:

1. Exponent

2. Multiplication

3. Subtraction

4. Square root

5. Addition

6. Division?

<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>

the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?
FinnZ [79.3K]
ANSWER

The other zero is

x =  - 10

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.


We were given that the axis of symmetry of the quadratic equation is
x =  - 3


We were also given that, one of the zeroes of the quadratic equation is
x = 4


Let the other zero of the quadratic equation be
x = p

,then, we apply the midpoint formula to find the value of
p

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,




\frac{x_1 + x_2}{2}  = axis \: of \: symmetry

We substitute to obtain,

\frac{p + 4}{2}  =  - 3



We multiply through by 2 to get,

p + 4 =  - 6



This implies that,

p =  - 6 - 4

p =  - 10

Which is f(-3) for the quadratic function graphed
hodyreva [135]
         We have to find on the graph which is f ( - 3 ).
         This is the quadratic function which passes through the points: ( - 6, - 3 ), ( 0 , - 3 ) and ( - 3, - 9 ).
         Also we can conclude that the point ( - 3, - 9 ) is the minimum value of this function. So : f ( - 3 ) = - 9.
        Answer:
        A ) - 9.
