Lisa is asked to draw a quadrilateral with the following specifications. adjacent angles are supplementary opposite angles are supplementary the measures of two adjacent sides are both 5 inches Which of the following statements about this quadrilateral is true.

Answers

Answer 1
Answer:

Answer:

B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)

Step-by-step explanation:

If all angles that are either adjacent or opposite are supplementary, all angles must be 90°

If at all times adjacent sides are 5 inches, all sides are equal.

Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

System of equations,

3x - 6y =2

5x + 4y = 1

Answers

3x-6y=2 (label equation 1)
5x+4y=1 (label equation 2)
-6y=-3x+2 (rearranged equation 1)
y=1/2x-1/3 (label equation 3)
 substitute equation 3 into equation 2 
5x+4(1/2x-1/3)=1
5x+2x-4/3=1
15x+6x-4=3 (multiplied everything by 3)

21x-4=3
     +4  +4
21x=7
x= 7/21
x=1/3
sub x=7/21 into equation 3
y= 1/2(1/3) -1/3
y= -1/6


Therefore x=1/3 and y= -1/6

Raphael paid $167 for a camera during a 75% off sale. what was the cameras regular price?

Answers

As the camera was at 25% of the original price, this means you've got to multiply this number to by 4 to get the original price.
167*4= 668
Therefore, the camera's regular price is $668
Hope this helps :) 
The original price of the camera was $292.25. I changed 75 percent to a decimal which became 0.75. Then I added $167 plus 0.75 which equals 292.25. When the dollar sign was added, $292.25 was the camera's original price. 

Hope I helped! :)

The graph of this quadratic function is a parabola. What is the equation of the axis of symmetry?y=x^2+-6x+5

Answers

Answer:

The answer to your question is x = 3

Step-by-step explanation:

Equation

                               y = x² + 6x + 5

Process

1.- Find the vertex

                              x² - 6x     = y - 5

                              x² - 6x + (3)² = y - 5 + (3)²

                              (x - 3)² = y - 5 + 9

                              (x - 3)² = y + 4                                

Vertex = (3, -4)

2.- It is vertical parabola and the axis of symmetry is parallel to the y-axis and crosses the point 3.

The equation of the axis of symmetry is   x = 3

Radius of a circle with diameter 240mm

Answers

The radius of the circle with the given diameter would be = 120mm.

What is the diameter of the circle?

The diameter of the circle is defined as a line segment that passes through the center of a circle and has two endpoints at the circumference.

The radius is defined as the distance from the centre of a circle to any point on the boundary. The radius:

= Diameter/2

Therefore, the radius of the circle = 240/2 = 120mm
