Answer:

6y+4x+5=0

Step-by-step explanation:

y=-(2/3)-(5/6)

y+2/3=-5/6

y+2/3+5/6= 0

y+4/6+5/6=0

Answer:

The 2 pound bag of gummy bears

Step-by-step explanation:

You do 1.5/4.35 which = 2.9 the 2.9 is $2.90 per pound

Then, you do 5.3/2 which = 2.6 this 2.6 is $2.60 per pound

$2.60 < $2.90 there for the 2 pound bag of gummy bears is the better deal

Select the correct answer.

Reptile [31]

Answer:

Option B R(2,4) is correct

Step-by-step explanation:

The equation of the circle is:

$(x-a)^2 + (y-b)^2 = r^2$

Where r = radius

a and b are coordinates of the center of circle.

To check which point lies on a circle, we need to verify the equation

$(x-6)^2 + (y-1)^2 = (5)^2$

We will check for each option.

Option A Q(1,11)

x=1 and y =11

$(1-6)^2 + (11-1)^2 = 25\\(-5)^2 + (10)^2 = 25\\25 + 100 = 25\\125 \neq 25$

So, Option A is incorrect

Option B R(2,4)

x =2 and y = 4

$(2-6)^2 + (4-1)^2 = 25\\(-4)^2 + (3)^2 = 25\\16 + 9 = 25\\25 = 25$

Option B is correct.

Option C S(4,-4)

x =4 and y =-4

$(4-6)^2 + (-4-1)^2 = 25\\(-2)^2 + (-5)^2 = 25\\4 + 25 = 25\\29 \neq 25$

Option C is incorrect

Option D T(9,-2)

x =9 and y =-2

$(9-6)^2 + (-2-1)^2 = 25\\(3)^2 + (-3)^2 = 25\\9 + 9 = 25\\18 \neq 25$

Option D is incorrect.
