They are vertical angles, and so set them equal to each other

x + 40 = 3x

Isolate the x. Subtract x from both sides

x (-x) + 40 = 3x (-x)

Simplify

40 = 3x - x

40 = 2x

Isolate the x. Divide 2 from both sides

40/2 = 2x/2

x = 40/2

x = 20

20, or (A) is your answer

hope this helps

in 1950, the U.S. federal budget was $39.4 billion, in 2000, the federal budget was $2025.2 billion. The exponential function is

Slav-nsk [51]

Answer:

The budget in 2010 is $4453.10915 billion

Step-by-step explanation:

We are given exponential function as

$f(t)=39.4e^{0.0787932t}$

where t is the time in years since 1950

now, we can find time in 2010

t=2010-1950=60

now, we can plug t=60

and we get

$f(60)=39.4e^{0.0787932\times 60}$

we get

$f(60)=4453.10915$

So, the budget in 2010 is $4453.10915 billion
