Identify which lines are parallel. y=2;y=x+2;y=2x-1;y=2x+1
1 answer:
Answer:
y=2
Step-by-step explanation:
A parallel line are lines that never intersect.
-They are generally formed when a line when lines are perfectly horizontal to the x axis or the vertical to the y-axis.
=>y=2 is the only parallel line .
=>y=x+2 is not parallel as the (x+2) is not a constant
=>y=2x-1 is not parallel as the (2x-1) is not a constant
=>y=2x+1 is not parallel as the (2x+1) is not a constant

Answer:
Number of child tickets = 800
Number of adult tickets = 330
Step-by-step explanation:
Let c = number of child tickets
and a= the number of adult tickets.
We are given:
The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults.
On a certain day, 1,130 enter the festival and 2, 520 is collected.
Making equations:
(because total people entered are 1130, so adding number of adult and child tickets will give us total number of people)
(because total money collected is 2520, so adding coat of adult and child tickets will give us total money)
Now, solving these equations simultaneously, we can find values of x and y
Let:
From equation 1 find value of c and put it in eq(2)
Putting value of c in eq(2)
So, we get value of a = 330
Now, punting value of a in eq(1) to get value of c
So, we get value of c = 800
Therefore:
Number of child tickets = c= 800
Number of adult tickets = a = 330
Answer:
y = (1/3)x + 10.
Step-by-step explanation:
The path of the baseball is shown in the image below. We can see that the baseball passes through the point (0, 0) and (60, 20). The equation of the baseball path is gotten using the formula:
The equation of a straight line is given as y = mx + b, where m is the slope, b is the y intercept
The slope of the baseball path is 1/3
The second player is at (90, 40) and runs parallel to the baseball path.
If two lines are parallel then they have the same slope.
Since the player moves parallel to the baseball path, the slope would also be 1/3. The equation of the players path is gotten using:
