Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)
__
This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form
x +2y = 3 . . . . . . . . . standard form
In the triangle below, which of the following best describes Xy?
Y
40°
40°
A. Angle bisector
B. Median
C. Altitude
O
D. Perpendicular bisector
Answer:
option A is correct answer of this qn
The word which best describes XV is Angle Bisector.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given is a triangle XYZ.
Here a line segment is drawn from the vertex X to the opposite side YZ.
Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.
Here, it is not given that, YV = ZV, so it is not median.
Altitude is the perpendicular line joining the vertex to the opposite side.
Here, it is not given the line is perpendicular. so it is not altitude.
Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.
Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.
So the line is angle bisector.
Hence the correct option is Angel Bisector.

There are 10 animals in the field. some are buffalo and some are ducks there are 34 legs in all. how many of each animal are in the field?
Answer:
7 buffalos and 3 ducks
Step-by-step explanation:
create a system of equations:
4 y + 2 x = 34
y + x = 10
* y is for buffaos and x is for ducks
solve the equation:
y=10-x
4(10-x)+2x=34
x=3
y=10-3
y=7
7 buffalos and 3 ducks

Answer:
if it is a trapzium then area will 14.5 ft sq
Answer:
area = 14.5 ft^2
Step-by-step explanation:
area = (6.5 x 2) + (0.5)(1.5)(2) (the base of the triangular shape is 8 - 6.5 = 1.5)
area = 13 + 1.5 = 14.5 ft^2

Identify the LCD: It is 24
Therefore we have:
14 21/24 - 15 - 20/24 - 14 21/24
Combining the whole numbers, we get
14 - 15 - 14, or -15
and combining the fractions, we get
21 - 20 - 21
----------------- = -20/24
24
and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6
