Answer:
The equation r = 3 - cos Ф is correct for the graph ⇒ 3rd answer
Step-by-step explanation:
Equations of the form r = a + b sin Ф, r = a - b sin Ф, r = a + b cos Ф, and r = a - b cos Ф represent limacons
- Equations r = a + b sin Ф, r = a - b sin Ф are symmetric to the vertical axis
- Equations r = a + b cos Ф, r = a - b cos Ф are symmetric to the horizontal axis
- The shape of the limacons depends on the values of a and b
∵ The figure is a circle
- That means a is greater than twice b
∴ a > 2b
∵ The circle is symmetric to the x axis
∵ The majority of the circle lies in quadrants two and three
- That means most of the graph at the negative part of x
∴ The form of the equation is r = a - b cos Ф
Lets look to the answer to find the right one
∵ a > 2b
∴ a = 3 and b = 1 because 3 > 2(1)
∴ The answer is r = 3 - cos Ф
The equation r = 3 - cos Ф is correct for the graph

Answer:
(6,4)
Step-by-step explanation:
This question asks you to dilate by a factor of 2, and from the origin. Because it is from the origin, we can simply multiply the coordinates of Y by 2
3*2=6
2*2=4
so the result is 6,4
Answer:
11x
Step-by-step explanation:
4(x+3)+2x=6(x+2)
BIDMAS
x+3=3x
x+2=2x
3x+2x+2x7x
7x+4=11x
i think im so sorry if this isnt helpful
