Answer:
A. y= -2x-3
Step-by-step explanation:
multiply the parenthasis by -2 to get -2x-8 then add 5 to both sides with equals y= -2x-3
6x + 6 > 3x+ 15
3x > 9
x > 3
You would put the number of bottles sold on the "x" axis and the cost on the "y" axis. If you graph properly it will show a linear relationship, which means you'll have a line like this ➝ / that corresponds with the data.
Answer:
5ft > can ride the roller coaster??
Step-by-step explanation:
im not 100% sure what u mean
Step-by-step explanation:
x² + (y − 1)² = 9
This is a circle with center (0, 1) and radius 3. We can parameterize it using sine and cosine.
Use the starting point to determine which should be sine and which should be cosine.
Use the direction to determine the signs.
Use the number of revolutions and the interval to determine coefficient of t.
(A) Once around clockwise, starting at (3, 1). 0 ≤ t ≤ 2π.
The particle starts at (3, 1), which is 0 radians on a unit circle. It makes 1 revolution (2π radians). Therefore:
x = 3 cos t
y = 1 − 3 sin t
(B) Two times around counterclockwise, starting at (3, 1). 0 ≤ t ≤ 4π.
The particle starts at (3, 1), which is 0 radians on a unit circle. It makes 2 revolutions (4π radians). Therefore:
x = 3 cos t
y = 1 + 3 sin t
(C) Halfway around counterclockwise, starting at (0, 4). 0 ≤ t ≤ π.
The particle starts at (0, 4), which is π/2 radians on a unit circle. It makes 1/2 revolution (π radians). Therefore:
x = -3 sin t
y = 1 + 3 cos t
