Answer:
n > 2 or n < 6
Step-by-step explanation:
3 - | 4 - n | < 1
Let's move 3 to the other side of the equation:
- | 4 - n | < 1 - 3
- | 4 - n | < -2
Both sides of the equation are negative, so we can simplify by multiplying them with -1:
(- | 4 - n | < -2*-1
| 4 - n | < 2
We cannot get rid of the module because it's not for a single number and we dont know what n is equal to but there is a rule that we can use to remove the module:
- if | x | < a and a > 0 then -a < x < a. So if we use it we get the following:
- 2 < 4 - n < 2
These are two equations, separate and solve them separately
4 - n < 2
- n < 2 - 4
- n < -2
n > 2 (< turns into > because we changed sign)
and
- 2 < 4 - n
4 - n > -2
-n > -2 - 4
n < 6 (we change the sign of the numbers so the equation changes too)
So after solving the two equation we get the answers
Find a solution to the system of equations.
5x+2y=16
7x+3y=23
X= Y=
Answer:
x = 2 and y = 3
Step-by-step explanation:
-3(5x+2y=16)
2(7x+3y=23)
-15 x - 6y = -48
14 x + 6y = 46
the y's cancel out
- x = - 2
x = 2
5x + 2y = 16
5(2) + 2y = 16
2y = 6
y = 3
Find the area of the composite figure.
So in fig 1 :
L = 14m W = 9mArea = L × WArea = 9 × 14Area = 126 m²In fig 2 :
L = 7mW = 16 - 9 = 7mArea= L × WArea = 7 × 7Area =49m² TA = 126 + 49TA = 175 m²The area of the composite figure is,
A = 175 m²
We have to given that,
A composite figure is shown.
In first part,
Lenght (L) = 14m
Width (W) = 9m
Hence, We get;
Area = L × W
Area = 9 × 14
Area = 126 m²
For second part,
Lenght (L) = 7m
Width (w) = 16 - 9 = 7m
Hence, We get;
Area= L × W
Area = 7 × 7
Area =49m²
So, We can formulate;
The area of the composite figure is,
A = 126 + 49
A = 175 m²

Are they similar or why are they not
Answer:
Yes they are similar due to the parallel lines of XY & BC. So, technically, the small and big triangle both will share the same base angles because corresponding angles are equal. Thus, angle AYX will be equal to angle YCB, for example.
In addition, two shapes are similar if one is an enlargement of another.

Find the distance between (−4, −3) and (−2, 0). Round your answer to the nearest tenth.
Answer:Given the two points you entered of (-4, -3) and (-2, 0), we need to calculate 8 items:
Item 1: Calculate the slope and point-slope form:
Slope (m) = y2 - y1
x2 - x1
Slope (m) = 0 - -3
-2 - -4
Slope (m) = 3
2
Calculate the point-slope form using the formula below:
y - y1 = m(x - x1)
y - -3 = 3/2(x + 4)
Item 2: Calculate the line equation that both points lie on.
The standard equation of a line is y = mx + b where m is our slope, x and y are points on the line, and b is a constant.
Rearranging that equation to solve for b, we get b = y - mx. Using the first point that you entered = (-4, -3) and the slope (m) = 3/2 that we calculated, let's plug in those values and evaluate:
b = -3 - (3/2 * -4)
b = -3 - (-12/2)
b = -6
2
-
-12
2
b = 6
2
This fraction is not reduced. Using our GCF Calculator, we see that the top and bottom of the fraction can be reduced by 6
Our reduced fraction is:
1
0.33333333333333
Now that we have calculated (m) and (b), we have the items we need for our standard line equation:
y = 3/2x + 3
Item 3: Calculate the distance between the 2 points you entered.
Distance = Square Root((x2 - x1)2 + (y2 - y1)2)
Distance = Square Root((-2 - -4)2 + (0 - -3)2)
Distance = Square Root((22 + 32))
Distance = √(4 + 9)
Distance = √13
Distance = 3.6056
Item 4: Calculate the Midpoint between the 2 points you entered. Midpoint is denoted as follows:
Midpoint =
x2 + x1
2
,
y2 + y1
2
Midpoint =
-4 + -2
2
,
-3 + 0
2
Midpoint =
-6
2
,
-3
2
Midpoint = (-3, -3/2)
Item 5: Form a right triangle and calculate the 2 remaining angles using our 2 points:
Using our 2 points, we form a right triangle by plotting a 3rd point (-2,-3)
Our first triangle side = -2 - -4 = 2
Our second triangle side = 0 - -3 = 3
Using the slope we calculated, Tan(Angle1) = 1.5
Angle1 = Atan(1.5)
Angle1 = 56.3099°
Since we have a right triangle, we only have 90 degrees left, so Angle2 = 90 - 56.3099° = 33.6901
Item 6: Calculate the y intercept of our line equation
The y intercept is found by setting x = 0 in the line equation y = 3/2x + 3
y = 3/2(0) + 3
y = 3
Item 7: Determine the parametric equations for the line determined by (-4, -3) and (-2, 0)
Parametric equations are written in the form (x,y) = (x0,y0) + t(b,-a)
Plugging in our numbers, we get
(x,y) = (-4,-3) + t(-2 - -4,0 - -3)
(x,y) = (-4,-3) + t(2,3)
x = -4 + 2t
y = -3 + 3t
Calculate Symmetric Equations:
x - x0
z
y - y0
b
Plugging in our numbers, we get:
x - -4
2
y - -3
3
Step-by-step explanation:
The distance between (-4, -3) and (-2, 0) rounded to the nearest tenth is approximately 3.6 units.
What is coordinate geometry?A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.
The distance between two points (x1, y1) and (x2, y2) in a 2-dimensional plane is given by the distance formula:
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
Using this formula, we can find the distance between (-4, -3) and (-2, 0) as follows:
D = √ [ ( 0 + 3)² + (-2 + 4 )² ]
D= √(2² + 3²)
D = √(13)
D ≈ 3.6
Therefore, the distance between (-4, -3) and (-2, 0) rounded to the nearest tenth is approximately 3.6 units.
