Answer:
They are equivalent
Step-by-step explanation:
3/6 is equal to 1/2
2/4 is equal to 1/2
Ah, thank you. your question truly made the most of sense.
Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).
Answer:
mph or miles per hour
Step-by-step explanation:
Answer:
y=45x+25
Step-by-step explanation:
y=45x+25
25 is a one-time fee so it is at the end. 45 is the monthly fee so it goes in front of x.
