Answer:
(x+8)² + (y+9)² = 100
Step-by-step explanation:
The equation for a circle on a graph is
(x - a)² + (y - b)² = r²
r represents the radius
a represents the x displacement of the circle's center.
b represents the y displacement of the circle's center.
First, I add all of my prices together.
$9.50(2)+$7.95+$7.95+$49.95= $84.85
Change 6% to a decimal = .06
Then multiply: 84.85 x .06 = $5.09
$5.09 is the sales tax
$84.85 + $5.09 = $89.94
Answer: $89.94
I hope this helps :)
Answer:
Yes
Step-by-step explanation:
If you observe you can see that 1x=2y
For example 2(x)=4(y)
If you insert this in the others it makes sense making it proportional.
Hope this helps

Since we are given that the student has a brand Y phone, they are one of a sample of only 580 students. Since 80 of those students also own a brand X (they own both) the probability that the random student is one of those is 50/580 = 5/58 = 8.62%
Answer:
and ![\sqrt{13}](https://tex.z-dn.net/?f=%5Csqrt%7B13%7D)
Step-by-step explanation:
Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.
For example, if the roots of a polynomial are 2 +
, 3 and 4 - 3i, then 2 -
, and 4 + 3i are also roots of the polynomial.
Therefore, since the given polynomial has rational coefficients and some of its roots are ,
and -
, then -
and
are also roots of the polynomial.
