X=number of miles
stars cost is 35+price for driving
price for driving=cost per mile times number oof miles
starts=35+0.25x
express is 17+0.4x
when will prices be equal?
set eaqual to each other
35+0.25x=17+0.4x
subtract 0.25x from both sides
35=17+0.15x
subtract 17 from both sides
18=0.15x
divide both sides by 0.15
120=x
answer is 120 miles
answer is D
Answer:
Domain; [-1, 3)
Range; (-5, 4]
Step-by-step explanation:
The domain of a function is defined as the set of x-values for which the given function is real and defined. In order to find the domain of the graphed function, we have to determine the lowest and the highest x-values for which the function is defined. From the graph, the least value of x is -1 while the greatest x value is 3 but the function is not defined at this point. Therefore the domain of the function is;
[-1, 3)
On the other hand, the range refers to the set of y-values for which the function is real and defined. The least y-value from the given graph is -5 while the greatest y -value is 4. Therefore, the range of the graphed function is;
(-5, 4]
Answer:
y = 1/2x - 1
Step-by-step explanation:
The x value is divided by 2 and then has 1 subtracted from it.
also for future posts, put the question in the title that way people know what you need and can click if they know the answer.
![\dfrac{3.6\cdot 10^{7}\,m}{3\cdot 10^{8}\,m/s}=0.12\,s](https://tex.z-dn.net/?f=%5Cdfrac%7B3.6%5Ccdot%2010%5E%7B7%7D%5C%2Cm%7D%7B3%5Ccdot%2010%5E%7B8%7D%5C%2Cm%2Fs%7D%3D0.12%5C%2Cs)
It takes 0.12 seconds for the radio signal to reach the surface from the satellite.

3(3a) = 9a
3(4) = 12
3(3a +4) = 9a +12
