Given quadrilateral TUVX ~ quadrilateral MNOP and VX = 5, XT = 10, and OP = 7, what is PM?

Answers

Please see the pic, I'd solved in it.
(PM)/(OP)=(XT)/(VX)
(PM)/(7)=(10)/(5)
We can either simplify 10/5 to 2 or just continue.
(PM)/(7)=2
PM=7 units
OR
PM×5=10×7
5PM=70
PM=14 units
We get the same answer either ways.

Which system of linear inequalities is represented by the
graph?

Answers

Answer:

y <x+1

y>x-2

Step-by-step explanation:

According to the graph, the system is formed by two inequalities. Let's find out the equation to each line in first place.

Notice that the upper line passes through points (-1,0) and (0,1). First, we find its slope

m=(y_(2)-y_(1) )/(x_(2)-x_(1) )=(1-0)/(0-(-1))=(1)/(1)=1

Then, we use the point-slope formula to find the equation

y-y_(1) =m(x-x_(1) )\ny-0=1(x-(-1)\ny=x+1

Now, the dashed line indiactes that the inequalities must have sings < or >.

Notice that point (0,0) is part of its solution, that means the inequality is

y <x+1

We do the same process to find the other inequality.

The line passes through points (0,-2) and (2,0).

m=(y_(2)-y_(1) )/(x_(2)-x_(1) )=(0-(-2))/(2-0)=(2)/(2)=1

Then,

y-y_(1) =m(x-x_(1) )\ny-0=1(x-2)\ny=x-2

Notice that point (0,0) is part of its solution, so the inequality is

y>x-2

Therefore, the system of inequalities is

y <x+1

y>x-2

Answer:

y<x+1      y>x-2

Step-by-step explanation:

upper line: (0,1) (-1,0)

y=x+1

Lower line: (0,-2) (2,0)

y=x-2

I did not see any solid boundry on the line

Shaded: y<x+1      y>x-2

What is the approximate area of a circle with a radius of 13cm? A.40.8cm² B.530.7cm² C.784cm² D.2461.8cm²

Answers

It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths 
the area of a circle can be found by the formula A=pi*r^2. Pi equals 3.14 so multiply that by 13^2. 13^2 equals 169. So 3.14 * 169 = 530.66 cm^2 and that rounded is B) 530.7cm^2
