Identify the segment bisector of —
XY
Answer:
line n
Step-by-step explanation:
Line 'n' is the segment bisector.
We have a line segment XY given in figure.
We have to identify its segment bisector.
Define Segment bisector.A segment bisector divides a line segment into two equal parts.
According to the question, we have -
Line Segment XY and its Mid - Point M. It can be seen that the line 'n' is the segment bisector of the segment XY.
Hence, line 'n' is the segment bisector.

how to factorise
x^2-9
Answer:
[tex](x+3)(x-3)[/tex]
Step-by-step explanation:
This equation is called a "difference in perfect squares".
The resulting answer should be: [tex](x + y)(x-y)[/tex] where the y variable is the square root of the given number. In this instance, the integer 9
So knowing that the square root of 9 is 3 we can plug in 3 for both of the y spots which results in our answer.
If you wish to check this answer you can peform the "FOIL" method (first, outside, inside, last) in order to solve the equation which would result in:
[tex]x^{2}-9[/tex]

Answer:
417,808
Step-by-step explanation:
original weight = x
A 27% decrease is the same as multiplying by 0.73
27% = 0.27
1 - 0.27 = 0.73
x × 0.73 = 305,000kg
To find x, divide 305,000kg by 0.73
305,000 ÷ 0.73 = 417,808.2192 ≈ 417,808

Find the x and y intercepts for the following equation. 2x– 7y=-14
A. X int. = -7 Yint. = 2
B. X int. = 7 Yint. = -2
C. Xint. = 2 Yint. = -7
D. X int. = -2 Y int. = 7
Answer:
C: Xint = 2, Yint. = -7
Step-by-step explanation:
Given the equation, 2x - 7y = -14:
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0. To solve for the y-intercept, set x = 0:
2x - 7y = -14
2(0) - 7y = -14
0 - 7y = -14
-7y = -14
Divide both sides by -7 to solve for y:
-7y/-7 = -14/-7
y = 2
Therefore, the y-intercept = 2.
Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:
2x - 7y = -14
2x - 7(0) = -14
2x - 0 = -14
2x = -14
Divide both sides by 2 to solve for x:
2x/2 = -14/2
x = -7
x-intercept = -7.
Therefore, the correct answer is C: Xint = 2, Yint. = -7

What is the multiplicative inverse of 1 5/42
Answer:
I'm not to sure
Answer:
inverse of 5/42 = -42/5 = -8 2/5 = -8.4
inverse of 15/42 is flipped -42/5 = -2.8
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= 8.4
if 15/42 then -1/1 ÷15/42 = -14/5
= -2.8
Step-by-step explanation:
if the question was 15/42 then we divide by -1 /15/42 = -42 / 15
so we can divide all by -1 or -1/1
The calculation steps are ;
-1/1÷ 15/42
= -1/1×42/15
= -1 × 42 / 1 × 15
= -42/15
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= -8.4
if 15/42 then -1/1 ÷15/42 =–14/5
= –2.8

are 9 and 1/9 reciprocals?
Answer:
yes
Step-by-step explanation:
9 can be represented as 9/1, which is the reciprocal of 1/9.
Answer:
yes, they are
Step-by-step explanation:
Since a reciprocal is basically an inverse fraction,
9 is also known as 9/1
whn inverted, you get 1/9.
the same applies vice versa
1/9 --> 9/1
therefore, making then reciprocals

What re linear angles
Answer:
In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other. The linear pair of angles are always supplementary as they form on a straight line. In other words, the sum of two angles in a linear pair is always 180 degrees.
