Answer:
Step-by-step explanation:
if center=(h,k)
radius=r
eq. of circle is (x-h)^2+(y-k)^2=r^2
given eq. is (x-5)^2+(y+2)^2=16=4^2
comparing
center =(5,-2)
radius r=4
Answer:
I think x = 1.5
Step-by-step explanation:
23 - 17 = 6
6 ÷ 4 = 1.5
Answer:
Distance between two points= √(x2-x1)²+(y2-y1)²
D= 15units
Let "k" be the y-coordinate of A
A(-6,k)
B(3,2)
15= √(3--6)²+(2-k)²
Taking square of both sides to eliminate the square root.
15²=(9)²+(2-k)²
225=81+4-4k+k²
k²-4k - 140=0
Using Quadratic Formula to evaluate
k= 14 or k=-10
The Possible coordinates of A are
(-6,14) or (-6,-10)
Answer:
Step-by-step explanation:
<u>Let the cost of daylilies = d and ivy = i, then we have below equations:</u>
- d + 12i = 114
- 10d + 10i = 150
<u>Simplify the second equation:</u>
<u>Subtract the second equation from the first:</u>
- d - d + 12i - i = 114 - 15
- 11i = 99
- i = 9, ivy costs $9
<u>Now find d:</u>
- d = 15 - 9 = 6, daylilies cost $6
