Vertex = (2, 2)
Range = {f(x): f(x) >= 2}
Answer:The dependency ratio is an age-population ratio of those typically not in the labor force and those typically in the labor force. It is used to measure the pressure on the productive population
Step-by-step explanation:
it’s system of substitutions ?
so try
a = 2
b = 5

A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so

A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So




We can rewrite that without the primes and combine the powers of 2.

Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
Answer:
2. 4a+2c = 5000
4. a + c = 1600
