Billy's dog weighs 30 pounds. Ruth's dog weighs two sixths as much as Billy's dog. How many pounds do Billy's dog and Ruth's dog
GaryK [48]

The number of pounds that Billy's dog and Ruth's dog weigh in all is; 40 pounds

<h3>Algebra Word Problems</h3>

Weight of billy's dog = 30 pounds

Weight of Ruth's dog = 2/6 of billy's dog = 2/6 * 30 = 10 pounds

Thus, total weight of both billy and ruth's dog is;

Total weight = 30 + 10

Total weight = 40

If the range of the coordinate transformation (, ) = (−2,−3 +1) is (4, −2), (2, −5), (−6, 4), what is the domain?
Alex17521 [72]

Consider the below figure attached with this question.

Given:

The transformation is:

f(x,y)=(-2x,-3y+1)

The range is (4,-2), (2, −5), (−6, 4).

To find:

The domain of the transformation.

Solution:

We have,

f(x,y)=(-2x,-3y+1)

For the point (4,-2),

(-2x,-3y+1)=(4,-2)

On comparing both sides, we get

-2x=4

x=\dfrac{4}{-2}

x=-2

And,

-3y+1=-2

-3y=-2-1

-3y=-3

y=\dfrac{-3}{-3}

y=1

So, the domain of (4,-2) is (-2,1).

Similarly,

For the point (2,-5),

(-2x,-3y+1)=(2,-5)

On comparing both sides, we get x=-1,y=2. So, the domain of (2,-5) is (-1,2).

For the point (-6,4),

(-2x,-3y+1)=(-6,4)

On comparing both sides, we get x=3,y=-1. So, the domain of (-6,4) is (3,-1).

So, the domain of the given transformation is (-2, 1), (-1, 2), (3, -1).

Therefore, the correct option is A.
