Id say <em>2 and 3 . </em><em /> It has to reflect off of the Y axis to look like the red figure. Other than that I can't help.
Answer:
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal .
Step-by-step explanation:
Given as :
The cost of each calendar = $ 9
The number of calendar sold to the family = 16
The number of calendar sold to the neighborhood = 14
So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood
i.e Total number of calendar sold by Celia = 16 + 14 = 30
∵ The cost of each calendar = $ 9
∴ The cost of 30 calendar = $ 9 × 30 = $ 270
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal . Answer
X² + 8x +y² - 2y -64 =0
We see that the equation has x² and y² . Also we see that coefficients in front of x² and y² are equal. So this is an equation of the circle.
(x² + 8x) +(y² - 2y) -64 =0
(x² + 8x) +(y² - 2y) = 64
We need to complete square for x and y groups, that means it should be written in form (a+b)² or (a-b)².
Expressions in parenthesis we will write as a²+/-2ab+b², to write it after as (a+/-b)², because a²+/-2ab+b² = (a+/-b)²
(x² + 2*4x) +(y² - 2*1y) = 64
(x² + 2*4x+4²) +(y² - 2*1y+1²) = 64+4²+1²
(x+4)² + (y-1)²= 81 Sometimes this is called a standard form of the circle.
(x+4)² + (y-1)²= 9² Sometimes it is required to write like this.
And if you are studying circles,ellipses and hyperbolas, the standard form should look like
42,812 and 62,812! You just add and subtract 10,000 from 52,812 and you will get the answer! Hope this helps!
