4. The system of equations 3x – 6y = 20 and 2x – 4y = 3 is

expeople1 [14]

3x - 6y = 20
-6y = -3x + 20
y = 1/2x - 20/6.....slope = 1/2...y int = -20/6 = -10/3

2x - 4y = 3
-4y = -2x + 3
y = 1/2x - 3/4..slope = 1/2...y int = -3/4

same slope, different y int = parallel lines = no solution = inconsistent

Jet001 [13]

Answer:

f(x-7) = x -12

Step-by-step explanation:

horizontal translation 7 units right: f(x-7)

f(x) = x - 5

The expression below shows the population of foxes in a forest after 12x years.

Mazyrski [523]

We know that:
$(x^{m}) ^{n}= x^{mn}$
$f(x)= 50*(1.05) ^{12x} = 50 * ( 1.05^{12})^{x} = \\ =50*(1.7959) ^{x}$
Answer: A ) f ( x ) = 50(1.05)^x
