Answer:

16 miles

Step-by-step explanation:

If 1.5 inches is equal to 4 miles, it would also mean that  3 inches is equivalent to 8 miles, since 4*2=8 and 1.5*2=3. Since we need to find it for 6 inches, we just double the number again to get 6 inches = 16 miles. (3*2=6; 8*2=16)

What is the slope of the line that passes through the points (-8, -3) and
Alchen [17]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)

m = \frac{-3+3}{-12+8} = \frac{0}{-4} = 0

Let C ( t ) be the number of US cell phone subscribers in millions in t years since 1995. A linear model for the data is F ( t )
Andru [333]

ANSWER

In 16 years time.


EXPLANATION.



If the number of subscribers is 324 million, then it means


f(t)=324


But we were given that,


f(t)=18.997t+16.711



This implies that,


324=18.997t+16.711


We now solve for t,



324-16.711=18.997t



307.289=18.997t



\frac{307.289}{18.997}=t



16.17566=t



That will be approximately in the 16th year.
