Part A:

We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.

Part B:

As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.

Answer: Option D. y+2x=3


Solution

If a line with a slope of -2:

Slope: m=-2

crosses the y-axis at (0,3):

(0,3)=(0,b)→b=3

What is the equation of the line?

y=mx+b

Replacing the known values:

y=-2x+3

Adding 2x both sides of the equation:

y+2x=-2x+3+2x

y+2x=3

Find the hypotenuse of an isosceles right triangle when the legs each measure 3\sqrt{x} 2inches.
Tresset [83]

The hypotenuse of the right triangle measures 3 units.

<h3>How to find the hypotenuse?</h3>

Here we know that both legs measure:

L  =\frac{3}{\sqrt{2} }

If we use the Pythagorean theorem, we will see that the hypotenuse H can be written as:

H^2 = (\frac{3}{\sqrt{2} } )^2 +  (\frac{3}{\sqrt{2} } )^2 \\\\H^2 = \frac{9}{2} + \frac{9}{2} = \frac{18}{2} = 9\\\\H = \sqrt{9} = 3

Then we conclude that the hypotenuse of the right triangle measures 9 units.

If the area of a square plot of<br> land is 9 miles squared, what is<br> the perimeter of this land?
tatyana61 [14]

Answer:

\huge{ \fbox{ \sf{12 \: miles}}}

Step-by-step explanation:

Given,

Area of a square plot = 9 miles

<u>First</u><u>,</u><u> </u><u>finding</u><u> </u><u>the</u><u> </u><u>length</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>land</u>

\boxed{ \sf{Area \: of \: a \: square \:  =  \:  {length}^{2} }}

\mapsto{ \sf{9 =  {length}^{2} }}

\mapsto{ \sf{ {length}^{2}  = 9}}

\mapsto{ \sf{ \sqrt{ {(length)}^{2} }} =  \sqrt{9} }

\mapsto{ \sf{length = 3 \: miles}}

<u>Now</u><u> </u><u>,</u><u> </u><u>finding</u><u> </u><u>the</u><u> </u><u>perimeter</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>land</u> :

\boxed{ \sf{perimeter \: of \: a \: square = 4 \: * length}}

\mapsto{ \sf{perimeter \:  =  \: 4 \:  * \: 3}}

\mapsto{ \sf{perimeter \:  = 12 \: miles}}

The perimeter of the land = 12 miles

Hope I helped!

Best regards! :D
