A railway system on a hillside moves passengers at a constant rate to an elevation of 50 m. The elevations of a train are given

for 2 different
locations.
a. Write an equation in point-slope form to represent the elevation of the train in terms of time. How can the equation be used to find the rate
of increase in elevation of the train in meters per second?
b. At what elevation does the train start initially? Write a linear equation in a form that gives the information as part of the equation. Explain
your reasoning
a. If x is the time in seconds and y is the elevation of the train in meters, then represents the elevation of the train in terms of time.
(Type an equation. Type your answer in point-slope form. Use integers or decimals for any numbers in the equation.)

Solve the simultaneous equations<br> x + 7y = 15<br> x + 2y = 5
Juliette [100K]

Answer:

x=1, y=2

Step-by-step explanation:

x + 7y = 15

x + 2y = 5

Subtract the two equations

x + 7y = 15

-x - 2y =- 5

------------------------

0x +5y = 10

Divide by 5

5y/5 = 10/5

y =2

Now find x

x+2y = 5

x +2(2) = 5

x +4 = 5

Subtract 4 from each side

x-4+4 = 5-4

x = 1

Which expression is equivalent? 8(3x − 6) A) 24x + 48 B) 24x − 48 C) −24x + 48 D) −24x − 48
Irina18 [472]
If this is distributive property, you would change 8(3x-6) to 8(3)x-8(6) and another way to say that is 24x-48 so it would be b and for d there are two negative signs which would equal positive so b and d
