Answer:

x = 1.75 -y, y = 1.25 + x

Step-by-step explanation:

Part One

2x + y = 3.5

<em>Divide</em>

x + y = 1.75

<em>Move the variable and change its sign</em>

x = 1.75 -y

Part Two

-x + 2y = 2.5

<em>Divide</em>

-x + y = 1.25

<em>Add</em>

y = 1.25 + x

In what year 200, the population of Virginia was about 7,400,000.
Rus_ich [418]
For this case we have the following function:
 f (x) = 7,400,000 (1,054) ^ x
 Where,
 x represents time in years.
 Substituting f (x) = 15000000 we have:
 15000000 = 7,400,000 (1,054) ^ x
 Clearing x we have:
 (1,054) ^ x = (15000000) / (7400000)
 log1.054 ((1.054) ^ x) = log1.054 ((15000000) / (7400000))
 x = log1.054 ((15000000) / (7400000))
 x = 13.4 years
 Rounding to the nearest year:
 x = 14 years
 Answer:
 
the population will reach 15,000,000 in 2014.

General form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)
jonny [76]

 

hello :<span>
<span>an equation of the circle Center at the A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
