Answer: one puppy weighs 5 pounds

Step-by-step explanation:

Let the weight of one puppy be x and the weight of adult dog be y.

Then from the first statement

3x + 3y = 60

Also from the second statement

4x + 2y = 50

combining the two equations together , we have

3x + 3y = 60 ............................... equation 1

4x + 2y = 50 ................................. equation 2

solving the system of linear equation by elimination method , multiply equation 1 by 4 and equation 2 by 3 , we have

12x + 12y = 240 ................................ equation 3

12x + 6y = 150 ....................................... equation 4

subtract equation 4 from equation 3

6y = 90

y = 15

substitute y = 15 into equation 1 to get the value of x.

3x + 3 ( 15 ) = 60

3x + 45 = 60

3x = 60 - 45

3x = 15

x = 5

1 puppy weighs 5 pounds and 1 adult dog weighs 15 pounds

Find the value of y. Round your answers to the nearest tenth
ANTONII [103]

Answer:

y ≈ 4.3

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{AB}{RS} = \frac{ED}{VU} , substitute values

\frac{6}{4} = \frac{8}{y+1} ( cross- multiply )

6(y + 1) = 32

6y + 6 = 32 ( subtract 6 from both sides )

6y = 26 ( divide both sides by 6 )

y ≈ 4.3 ( to the nearest tenth )

Which is one of the transformations applied to the graph of f(x)=x2 to change it into the graph of g(x) = -x2 + 16x – 44?
KatRina [158]

Answer:

Only option D is one of the transformations needed.

Step-by-step explanation:

The graph of f(x)=x^2 is a positive parabola with x=0 as the zero in ordinates and also 0 as a zero x. This is, the graph passes in (0,0) and this is the only point it crosses both axis, then for every x value we will gave a positive f(x).

Here I attach a graph that shows both, f(x)=x^2 and g(x)=-x^2+16x-44.

As you can see, for transforming f(x) in g(x) we need to reflect it over the x axis, as g is open downwards. Then, as the quadratic term is still being x^2 we do not wide it (as you see in the graph both curves are equally widened).

Then, we can also see that the graph is shifted right, so we do not shift it left 8 units (notice that we shift it right 8 units).

So, after reflecting over the x axis and shifting right we need to shift it UP, as we can see the graph is over the x axis.

So, the three transformations needed are:

1. reflect over the x axis

2. shift right 8 units

3. shift up 20 units.

So, from the options you proposed we chose only d, to which we MUST add the transformations noted above.

Sorry for the mistake!
