Answer:
0, 8/5
Step-by-step explanation:
You can use the app photo math you just take a picture of the problem and it gives you the answer and shows the steps:)
50 x 0.4 = $20
$50 - $20 = $30
Ratcliff
$40 x 0.3 = $12
$40 -$12 = $28
Although, Clothes R Us discount is larger, Ratcliff has the better deal because the sneaker cost $28 vs clothes r us $30.
Answer:
The answer to your question is: 3x² (x - 5) ²
Step-by-step explanation:
Factor like terms 3x⁴ - 30x³ + 75x²
3x² ( x² - 10x + 25)
Factor ( x² - 10x + 25) = ( x - 5) (x - 5) = (x - 5) ²
Finally 3x² (x - 5) ²
Answer
6yx^2/7

Answer:
the equation of the circle is
Step-by-step explanation:
Recall that the equation of a circle is given by 
where r is the radius, and (h,k) is the center. Recall that given two points that are the endpoints of a diameter, the center of the circle is their correspondent midpoint. Also, recall that given points (a,b), (c,d) their midpoint is obtained by 
In this case we are given the endpoints (-1,-9), (5,1). So the center of the circle is the midpoint obtained by 
. Recall that the radius of a circle is the distance from the radius to any of the points of the circle. So, the radius is the distance between the center and the point (-1,-9). We will calculate r^2, by using the distance formula. REcall that the distance between points (a,b), (c,d) is given by
![\sqrt[]{(a-c)^2+(b-d)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28a-c%29%5E2%2B%28b-d%29%5E2%7D)
. So, its square is
.
In our case,
So, the equation of the circle is
