Answer: $7.25 per pound

Step-by-step explanation:

3x3.5 + 5x = 46.75

5x+10.5 = 46.75

5x = 36.25

x = 7.25

Answer:

the price per pound for the turkey would be 7.25

Step-by-step explanation:

first you would do 3x3.50 to find the total cost for the cheese

now you subtract that from 46.75

once you have that answer you divide by 5 :)

Calculate the area of triangle ABC with altitude CD, given A(−7, −1), B(−1, 5), C(0, 0), and D(−3, 3)

Snezhnost [94]

Answer:

A=25 (Rounded)

Step-by-step explanation:

The first step is to find the length of BA which is the base, then you have the find the length of CD, the hight.

To find the distance, you need to use the distance formula which is

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$ (It does not matter if A is x1 or is B is x1, it just has to remain consistent)

I am going to first find BA

$d=\sqrt{\left({-7}-{-1}\right)^{2}+\left({-1}-{5}\right)^{2}}$

Next, subtract accordingly

$d=\sqrt{\left({-7}+{1}\right)^{2}+\left({-1}-{5}\right)^{2}}$

$d=\sqrt{\left({-6}\right)^{2}+\left({-6}\right)^{2}}$

Once you do that, you want to square -6 and -6 which will give you

$d=\sqrt{\left({36}\right)+\left({36}\right)}$

Now add 36 with 36 which will leave you with

$d=\sqrt{{72}}$

Do that same thing for CD. If you did it right, you should be left with

$d=\sqrt{{18}}$

to find the area of a triangle, you must use the formula

$A=\frac{B*H}{2}$

The Base is $\sqrt{{72}}$ (BA) and the Hight is $\sqrt{{18}}$ (CD). substitute to get

$A=\frac{\sqrt{{72}}*\sqrt{{18}}}{2}$

Multiply the Base by the Hight to get

$A=\frac{\sqrt{{1,296}}}{2}$

Divide 1,296 by 2 to get

$A=\sqrt{{648}}$

Which is equal to

$A=25.455844122715710878430397035775$

Rounding it to the nearest whole number you get

A=25

Hope this helps. Feel free to ask any follow-up questions.

Have a good day! :)

The range of which function includes –4?

TiliK225 [7]

Answer:

The function $f(x)=\sqrt{x-5}$

Step-by-step explanation:

The Range of any function is complete set of all possible resulting values of the dependent variable , after substituting the domain.

so, the function $f(x)=\sqrt{x-5}$ has range $f(x)$\geq$ -5$

This includes - 4 .

Hence, the function is $f(x)=\sqrt{x-5}$ .

Y= 2/3x -1 y= -x + 4

blondinia [14]

Answer:

$x=3\\y=1$

Step-by-step explanation:

To solve the system of equations you must apply the proccedure shown below:

- Make both equations equal to each other.

- Solve for x.

Then:

$\frac{2}{3}x-1=-x+4\\\\\frac{2}{3}x+x=4+1\\\\\frac{5}{3}x=5\\5x=5*3\\x=\frac{15}{5}\\\\x=3$

- Substitute the value of x obtained into any on the original equations to find y:

$y=-3+4\\y=1$
