A train's travel is represented by the equation y = 17.5x, where y represents the total number of miles the train travels in 3 hours. If this relationship is graphed on a coordinate plane, which statement is true?
The graph passes through (0,0) and (17.5, 1), and the slope represents the train traveling at a rate of 1 mile every 17.5 hours.
The graph passes through (0,0) and (17.5, 1), and the slope represents the train traveling at a rate of 17.5 miles every hour.
The graph passes through (2,35) and (4,70), and the slope represents the train traveling at a rate of 1 mile every 17.5 hours.
The graph passes through (2,35) and (4,70), and the slope represents the train traveling at a rate of 17.5 miles every hour.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

sorry i just need to anwers this to get points
