Answer:

x = 8

Step-by-step explanation:

The perimeter of a body is the sum of all its sides.

  Perimeter of the triangle;

       hypothenuse + opposite + adjacent  = x+6 + x + 3 + x + 9 = 3x + 18

  Perimeter of the rectangle  = x+1 + x + 4 + x + 1 + x + 4 = 4x + 10

Now,

 Since their perimeter is equal;

                           3x + 18 = 4x + 10

                             3x - 4x  = 10 - 18

                               -x  = -8

                               x = 8

Write an equation for a circle given that the endpoints of the diameter are
(-8,5) and (4,-3)

Answers

Answer: (2,2)

so Using the distance formula,

d = sqrt(x2-x1)^2 +(y2-y1)^2 .

Substituting the values of x and y.

we get,

d = sqrt(-4-8)^2 +(-3-7)^2

d = 2 sqrt 61  

diameter = 2*radius

              = 2 sqrt 61

              = 2 r

              = r

              = sqrt 61

          r^2 = 61  

midpoint of the diameter is:  

Xm= 8-4 / 2

     = 2  

Ym = 7-3 / 2  

     = 2  

Hence,

The center is (2,2)

2(x + 4) - 6 = 5x - 17

Answers

Answer:

x=6.3  :)

Step-by-step explanation:

2(x+4)-6=5x-17

2x+8-6=5x-17

2=3x-17

19=3x

19/3=6.3

Answer:

2(x+4) -6 = 5x-17

2x + 8 - 6 = 5x - 17

8 -6 + 17 = 5x - 2x

2 + 17 = 3x

19 = 3x

divide both side by the coefficient of x which is 3

19/3 = 3x/3

x = 19/3

x = 6 1/3. or 6.33

I Need help plz.ASAP

Answers

1-3/0--1 = -2/1 = -2

The slope is -2

y=-2x+b

1 = -2(0)+b

1 = b

The y-intercept is 1

The equation is

y = -2x + 1

First, we want to find the slope. To do this we use the equation y2-y1 / x2-x1. For the problem, we use the points (-1,3) and (0,1). This would look like: 3-0/1--1. This would simplify to 3/2. To find the y-intercept, find the point (0, y). In this problem, that point would be (0,1). Now you can plug this into y = mx+b. Therefore, your equation is y = 3/2x + 1.
