(x) basically means y, and f'(x) means dy/dx. The x can have a value, so for example, f(x) = 2x + 1, then f(1) = 3.

What is the value of x in the equation -6 x = 5 x + 22?<br> A. -22<br> B. -2<br> C. 2<br> D. 22

Novosadov [1.4K]

Answer:

B. -2

Step-by-step explanation:

-6x = 5x + 22

Put the like terms together, so subtract 5x from the right side. This will result in the new equation, -11x = 22

Now, divide by -11. This will result in the final equation, x = -2

The most recent census for a city indicated that there were 919,716 residents. The population of the city is expected to increas

OLEGan [10]

Answer:

1,474,951.

Step-by-step explanation:

Given a population that increases by a constant percentage, we can model the population's growth using the exponential model.

$P(t)=P_o(1+r)^t,$ where \left\{\begin{array}{lll}P_o=$Initial Population\\r$=Growth rate\\$t=time (in years)\end{array}\right\\P_o=919,716\\r=3.7\%=0.037\\$t=13 years$

Therefore, the population of the city in 13 years time will be:

$P(t)=919,716(1+0.037)^{13}\\\\=919,716(1.037)^{13}\\\\=1,474,950.9\\\\\approx 1,474,951$

The population be at that time will be approximately 1,474,951.

Really struggling on this

Angle 4 would be 77degrees because angle two is vertical to angle four.

Angle 3 and Angle 1 are equal because they are vertical to each other.

You would subtract 180 (degrees) minus 77 (degrees) and get 103 (degrees).

So Angle 3 and Angle 1 would both be 103 degrees.

You would get 180 degrees from the line.
