Answer:
i think its c
Step-by-step explanation:
As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.
In order to solve for x we can set up the proportion between the horizontal and vertical sides:

Solving this proportion for x implies 
Now you can solve for m and p using the pythagorean theorem, because both triangles are right:

Then, we know that the hypothenuse of the big triangle is m+p, so we have

which implies

So since this is a linear equation, which is y=mx+b, you use what it tells you in the word problem. so mx is the rate, since in this equation 200 per ton of sugar that's your mx, so its 200x. then for your b value, which in this case is the cost of truck rental, so its 5,400.
your equation is C=200s+5400
the variables are the same so you can use Y and X, but I used the variables used in the word problem.
Y=200x+5400
Answer:
sometimes true
Step-by-step explanation:
Answer: Y-intercept is (0,-1/7) and the slope is -3/7
Step-by-step explanation:
State the slope and the y-intercept for the graph of each
equation y= -3/7x–1/7
To find the y-intercept,
you plug in 0 in for x for y= -3/7x–1/7
y=-3/7(0)-1/7
y=0-1/7
y=-1/7
The y-intercept is (0,-1/7)
To find the slope, you first check that the equation is in the form of y=mx+b
y= -3/7x–1/7 is in the from of y=mx +b.
The m is the slope
hence, in y= -3/7x–1/7 the slope is -3/7
