X^2-8x+16=1\\ \\x^2-8x+16-1=0\\ \\x^2-8x+15=0\\ \\\Delta = b^{2}-4ac = (-8)^{2}-4*1*15=64-60=4 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{8- \sqrt{4}}{2}=\frac{8-2}{2}= \frac{6}{2}=3\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{8+ \sqrt{4}}{2}=\frac{8+2}{2}= \frac{10}{2}=5\\ \\Answer : x=3 \ \ or \ \ x = 5
Answer:
meter
Step-by-step explanation:
<h3>A submarine is at an elevation of -100 feet (100 feet below sea level). Let’s compare the elevations of these four people to that of the submarine:</h3>
- Clare’s elevation is greater than the elevation of the submarine. Clare is farther from sea level than the submarine.
- Andre’s elevation is less than the elevation of the submarine. Andre is farther away from sea level than the submarine.
- Han’s elevation is greater than the elevation of the submarine. Han is closer to sea level than is the submarine.
- Lin’s elevation is the same distance away from sea level as the submarine’s.
5×4=20 is closer to 24.9344.
Let's try placing the decimals after the hundreds place.
It works.
There is more than one possibility.
Answer:
x= -1
Step-by-step explanation:
Given data
We have the expression as
(x+1)/(x+1)= 1/2
let us first cross multiply
2(x+1)=(x+1)
2x+2=x+1
collect like terms
2x-x=1-2
x= -1
Hence the value of x=-1
