If <u>quadratic function </u>
has <u>vertex </u>that is the same as its <u>y-intercept</u>, then
and its equation is 
The graph of this quadratic function is translated graph of the function 
up or down (depends on c).
This means that there could be
- two x-intercepts;
- one x-intercept;
- no x-intercepts.
The axis of symmetry of the graph of the function is x=0 (y-axis).
Answer: correct choice is A
Hello,
315=1*180+135
180=1*135+45
135=3*45+0
GCF(315,180)=45
180/315=4*45/(7*45)=4/7
The cost per hour is $11, at that point, the coefficient of the quantity of hours Rita and Tina had worked. With respect to Rita, she will get an additional $32 level wage for her extra hours. It wont be duplicated any further. Mathematically:
Rita's Total Wages = 11r + 32
Tina's Total Wages = 11t
We let x and y be the number of Hobbies & Recreation and Soliloquies episodes that Steve subscribe. The system of linear equation that best represent the given above is,
x + y = 10
32x + 42y = 340
The values of x and y from the system are 8 and 2, respectively. Thus Steve subscribed to 8 Hobbies & Recreation and to 2 Soliloquies episodes.
To find the area you multiply l x w so, to find the sides you do the opposite, sq root of 24,200 (we can use the square root because we know it is a square and all sides are equal)=155.563492. This is only the length of one side. 155.563492*4=622.253968 which is a rational number.
The perimeter is a rational number.
