Answer:

Step-by-step explanation:

hello :

the distance between (0, 2) and (-4, 4)is : √((-4-0)²+(4-2)²) =√(16+4) =√20

but : 20 = 4×5 so :√20= √(4×5) =√4×√5 = 2√5....(answer: C)

Solve the following system of equations by graphing.

MrMuchimi

Answer:

<h2>Graph b</h2>

Step-by-step explanation:

The equation of a linear function in slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The graph of linear function is a straight line therefore we need only two points to the plotting the graph.

$-4x+3y=-12\qquad\text{add 4x to both sides}\\\\3y=4x-12\qquad\text{divide both sides by 3}\\\\y=\dfrac{4}{3}x-4\\\\for\ x=0\to y=\dfrac{4}{3}(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=3\to y=\dfrac{4}{3}(3)-4=4-4=0\to(3,\ 0)$

$-2x+3y=-18\qquad\text{add 2x to both sides}\\\\3y=2x-18\qquad\text{divide both sides by 3}\\\\y=\dfrac{2}{3}x-6\\\\for\ x=0\to y=\dfrac{2}{3}(0)-6=0-6=-6\to(0,\ -6)\\\\for\ x=3\to y=\dfrac{2}{3}(3)-6=2-6=-4\to(3,\ -4)$

Min-Jee is planting two rectangular flower beds. One bed is 2.78 feet by 4.81 feet, and the other bed is 2.78 feet by 5.61 feet.

Answer: $(2.78+4.81)(2.78+5.61)$

Step-by-step explanation:

<h3> The complete exercise is attached.</h3><h3></h3>

The area of a rectangle can be calculated with this formula:

$A=lw$

Where "l" is the lenght and "w" is the width.

Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.

Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.

Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:

$2.78*4.81 +2.78*5.61$
