Answer:
x=-4.73 x=-1.27
Step-by-step explanation:
(x + 3)^2 - 3 = 0
Add 3 to each side
(x + 3)^2 - 3 +3= 0+3
(x + 3)^2 = 3
Take the square root of each side
sqrt((x + 3)^2) =±sqrt( 3)
(x + 3) =±sqrt( 3)
Subtract 3 from each side
x + 3-3 =-3±sqrt( 3)
x = -3±sqrt( 3)
Approximating to 2 decimal places
x=-1.27 x=-4.73
Using the distance formula, the length of WX is approximately: 8.5.
<h3>How to Find the Length of a Segment Using the Distance Formula?</h3>
Distance formula is, .
Given the endpoints:
W(5,-3) = (x1, y1)
X(-1,-9) = (x2, y2)
Plug in the values:
WX = √[(−1−5)² + (−9−(−3))²
WX = √[(−6)² + (−6)²]
WX = √72
WX ≈ 8.5

Answer:
the answer is B x=2 y=6
Step-by-step explanation:
we can find by elimination or substitution method
For the first one it’s 1hour and 15 minutes, for the second one it’s x=3(2 1/4), x= 6 3/4, then 10- 6 3/4 = 3 1/4 not sure if that’s how you learned it but
Answer:
16000 bacteria after 60 days
Step-by-step explanation:
60 divided by 12 = 5
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
