Answer:
x = 2 and x = -2
Step-by-step explanation:
The easiest way is to guess. We know that you can't have a square root of a negative number. This constrains x between negative infinity to 2. Testing 2 and -2, we see that it satisfy the equation.
The more systematic approach is shown below
x= -2, 2
One hundred thirty nine thousand eight hundred fifty two
Well the 10,000 digit will be 1 and the thousand digit = 7 + 1 = 8
so the first 2 digits are 18
6 fewer than 8 = 2 so we get 182
1 fewer 10 than 1000's is 8-1 = 7 so we have 1827
and 5 fewer ones than 1000.s = 8 - 5 = 3
So our number is 18,273
Answer:
y - 1 = 1/6x + 1 <<< Point slope form
y = 1/6x + 2 <<< slope intercept form
Either one works unless the question specifies the form of the equation
Step-by-step explanation:
Point slope form: (y - y1) = m(x - x1)
Given: (-6,1) ; m = 1/6
(y - 1) = 1/6(x - (-6))
y - 1 = 1/6x + 1 <<< Point slope form
y = 1/6x + 2 <<< slope intercept form: y = mx + b
