How do I find reflect it? would I have to keep the points the same of would point B replace point A

Point A is at (-2, -2). When you reflect it over the x axis, the y coordinate flips from negative to positive. The x coordinate stays the same.

The reflection rule stated algebraically is (x,y) \to (x, -y), which means (x, y) turns into (x, -y)

So (-2, -2) becomes (-2, 2) after using that rule.

Repeat for points B through D

  • B is at (-2, -4) which moves to (-2, 4)
  • C is at (-5, -4) which moves to (-5, 4)
  • D is at (-5, -2) which moves to (-5, 2)

Check out the diagram below.

Count from each point to the x-axis across and go back out the same number on the opposite side of the x-axis

For instance from point d to the x axis is 2 so now start on the xaxis at -5,0 and go up 2 more so the new point for point D would be -5,2

The perimeter of the rectangular playing field is 320 yards. the length of the field is 4 yards less than triple the width. what
fgiga [73]
Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides


Check:
<span> 2 * 60 + 2 * 130 = 380 </span>

Using just yes or no, can you make more than one triangle when you are given 3 different line segments?
iogann1982 [59]

Answer:

No

Step-by-step explanation:

A triangle is made up of three line segments therefore, it would be impossible to make multiple triangles with only 3 line segments. You could stretch the line segments but they would never make other triangles since each attempt would be missing one line segment. What can be done with these 3 line segments is making more than one type of triangle. For example, we can make acute triangles, an obtuse triangle, right triangles, etc.

PLZZZ HELP ASAP!!!!!!!
patriot [66]

Answer:

2. y = x + 16; 0.21y = 0.27x + 2.88

Step-by-step explanation:

You have two conditions:

  • Volume of 18 % + volume of 27 % = volume of 21 %
  • Mass of acid in 18 % + mass of acid in 27% = mass of acid in 21 %

For the first condition,

16 + x = y     Transpose

(1)    y = x + 16

=====

For the second condition

  V₁c₁    +  V₂c₂  =  V₃c₃

16×0.18 + 0.27x = 0.21y

   2.88 + 0.27x = 0.21y               Transpose

(2)           0.21y = 0.27x + 2.88

The system of equations is y = x + 16; 0.21y = 0.27x + 2.88
