The answer is B. 2x-y=0, because parallel lines have the same slope (2x), and when you substitute 0 for Y, you get 0 for X-- the origin, (0,0)
The answer is 75
explanation: 180cm divided by 45 cm is 4, so 300cm divided by 4 is 75
Answer:
(-3,2)
Step-by-step explanation:
Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota
Answer:
(x, y) = (4, 3)
Step-by-step explanation:
The first equation gives an expression for y that can be substituted into the second equation:
3(2x -5) -x = 5
5x -15 = 5 . . . . . . simplify
5x = 20 . . . . . . . .add 15
x = 4 . . . . . . . . . . divide by 5
y = 2(4) -5 = 3 . . substitute for x in the first equation
(x, y) = (4, 3)

Solution by graphing confirms this result.
