Answer:

The domain of f(x) corresponds to the set of real numbers.

D f(x) ∈ ∀X; D f(x) ∈ R

Step-by-step explanation:

f(x)=X+18-3X-15

f(x)=-2X+3 (right line with negative slope)

This function exists for all values of X, so the domain corresponds to the set of real numbers.

D f(x) ∈ ∀X; D f(x) ∈ R

An oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours. Which graph has a slope that best represent
pentagon [3]

Answer:

Graph G

Step-by-step explanation:

The graphs are attached

Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours, hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour

Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per secong

The slope (rate of change) of a line (m) is given by:

m=\frac{y_2-y_1}{x_2-x_1}

a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:

Slope\ of\ line\ F=\frac{-20-0}{10-0} =-2\ meters\ per\ second

b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:

Slope\ of\ line\ G=\frac{-70-0}{10-0} =-7\ meters\ per\ second

c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:

Slope\ of\ line\ H=\frac{-35-0}{10-0} =-3.5\ meters\ per\ second

d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:

Slope\ of\ line\ j=\frac{-3.5-(-3.5)}{10-0} =0\ meters\ per\ second
