Answer:

(4, 4) is the solution to both lines A and B.

Step-by-step explanation:

The solution to a system of equations is the point at which the two lines intersect. Lines A and B intersect at point (4,4). This means (4,4) is the point which makes both equations true for the same values. The correct answer is     "(4, 4) is the solution to both lines A and B."

Cerrena [4.2K]

Answer:

<u><em>x=9</em></u>.

<em><u>perimeter=68</u></em>

<em><u>area=168</u></em>

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to  multiply the length and the width so 28x6 which is <em><u>168</u></em>.

hope that helped :)

A rectangular prism has a width of 51 ft and a volume of 144 ft3. Find the volume of a similar prism with a width of 17 ft. Roun
meriva

Answer:

5.3\ ft^3

Step-by-step explanation:

Similar shapes with scale factor k have proportional volumes with coefficient k^3 i.e.

\dfrac{V_{large}}{V_{small}}=k^3,

where

k=\dfrac{\text{width of large prism}}{\text{width of small prism}}.

Since

\text{width of large prism}=51\ ft,\\ \\\text{width of small prism}=17\ ft,

then

k=\dfrac{51}{17}=3.

Hence,

\dfrac{144}{V_{small}}=3^3\Rightarrow V_{small}=\dfrac{144}{27}=\dfrac{16}{3}=5\dfrac{1}{3}\approx 5.3\ ft^3.

Kristin graphed the locations of several places in her school on the coordinate plane shown below. Determine if each statement a
wel

Answer:

Step-by-step explanation:

1). Coordinates of Art → (1, -5).

   Coordinates of Library → (1, 9)

   Coordinates of Science → (-5, -5)

   Distance between Art and Library = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

                                                             = \sqrt{(1-1)^2+(9+5)^2}

                                                             = 14 units

   Distance between Art and Science = \sqrt{(1+5)^2+(-5+5)^2}

                                                               = 6 units

   Since 14 > 6,

   Art is closer to Science than Library.

   Answer is False.

2). Coordinates of Cafeteria → (-7, 9)

    True.
