Abby bought two slices of pizza and

Misha Larkins [42]

The solution is price of 1 slice of pizza is $ 1.75 and price of 1 bottle of water is $ 1.25

Solution:

Let "p" be the price of 1 slice of pizza

Let "b" be the price of 1 bottle of water

Given that Abby bought two slices of pizza and three bottles of water for $7.25

So we can frame a equation as:

two slices of pizza x price of 1 slice of pizza + three bottles of water x price of 1 bottle of water = $ 7.25

$2 \times p + 3 \times b = 7.25$

2p + 3b = 7.25 ------- eqn 1

Cameron bought four slices of pizza and one bottle of water for $8.25

So we can frame a equation as:

four slices of pizza x price of 1 slice of pizza + one bottles of water x price of 1 bottle of water = $ 8.25

$4 \times p + 1 \times b = 8.25$

4p + 1b = 8.25 ----- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "p" and "b"

Multiply eqn 1 by 2

4p + 6b = 14.5 ----- eqn 3

Subtract eqn 2 from eqn 3

4p + 6b = 14.5

4p + 1b = 8.25

( - ) ------------------

5b = 6.25

Substitute b = 1.25 in eqn 1

2p + 3b = 7.25

2p + 3(1.25) = 7.25

2p + 3.75 = 7.25

2p = 3.5

Thus the solution is:

price of 1 slice of pizza = $ 1.75

price of 1 bottle of water = $ 1.25

What is the equation for the line of reflection for ABCD to A’B’C’D’? Explain.

expeople1 [14]

Answer:

$y = \frac{4}{5} x - \frac{1}{5}$

Step-by-step explanation:

calculate midpoint of AA'

calculate midpoint of DD'

A(-5,1)

A'(-1,-3)

D(1,5)

D'(3,1)

then midpoint is

$\frac{x_{d} + x_{d^{1}}}{2} = 2 \\ \frac{y_{d} + y_{d^{1}}}{2} =3 \\ \\ \frac{x_{a} + x_{a^{1}}}{2} = - 3 \\ \frac{y_{a} + y_{a^{1}}}{2} = - 1$

then find slope

$\frac{ y_{2} -y_{1}}{x_{2} -x_{1}} = \frac{4}{5}$

then apply equation

$y = \frac{4}{5} x + b$

substitute any point of the 2 midpoints to find b

$b = \frac{ - 1}{5}$

then the equation is

$y = \frac{4}{5} x - \frac{1}{5} \\$
