Answer:
Domain: All Real Numbers
Step-by-step explanation:
Since this function is a linear function, it will use any x-value in order to continue with being a linear function. Therefore, if the line goes on for infinity, every x-value will be used for infinity. Therefore, the domain will be All Real Numbers since every number on the x-axis has a possibility of being used.
Prove ABCD is a parallelogram by showing both pairs of opposite sides are parallel, given the following points. Show all work!!! HELP PLEASEE
The prove that the angle ABCD is said to be a parallelogram that shows both pairs of opposite sides as parallel figure is given below.
What is the parallelogram about?The four points in the shape above are : A, B, C, D.
Where
A = (-2,-4)
B = (1,2)
C = (2,10)
D = (-1,4)
We place or sit vector AB with vector DC and vector AD with vector BC
and so we find and place their coordinates.
vector AB (1-(-2), 2-(-4))
vector DC (2-(-1),10-4)
vector AD (-1-(-2), 4-(-4))
vector BC (2-1,10-2)
So we obtained:
vector AB (3,6)
vector DC (3,6)
vector AD (1,8)
vector BC (1,8)
Next step is to calculate for the lengths :
AB= [tex]\sqrt{3^{2} + 6^{2} }[/tex] DC= [tex]\sqrt{3^{2} + 6^{2} }[/tex]
Thus, AB = DC
AD = [tex]\sqrt{1^{2} + 8^{2} }[/tex] BC =[tex]\sqrt{1^{2} + 8^{2} }[/tex]
Hence one can say that AD is equal to BC.
Therefore, angle ABCD IS known to be a parallelogram .

Answer:
z = 3[tex]\sqrt{13}[/tex]
Step-by-step explanation:
According to Euclidian theorem we can find the measure of z using the following equation:

What is the property of Exterior Angle of a Triangle ?According to the exterior angle property the measure of exterior angle is equal to the sum of opposite interior angles.
In the given figure it can be seen that one of the exterior angle is 90 degree ,
which is making a supplementary angle with the interior angle corresponding to it , angle B in the figure
Therefore the interior angle B is 90 degree ,
The value of angle C = p degree
To determine the value of angle C
The exterior angle next to angle A = 140 degree
By the exterior angle property
140 = 90 +p
p = 50 degree
The value of P is 50 degree , Option D is the correct answer.

Step-by-step explanation:
believe it or not, the area of any triangle is
baseline × height / 2
we have here 2 triangles, both with the same baseline (8 cm), but with 2 different heights : 6.5 cm and 4.6 cm.
so, their areas are
8 × 6.5 / 2 = 4 × 6.5 = 26 cm²
8 × 4.6 / 2 = 4 × 4.6 = 18.4 cm²
so, in total, the shaded region is

What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:

find x and y !!!!
pls pls help
Answer:
x = 59°, y = 31°
Explanation:
Angles (x) and (x - 28) sum ups to 90° on a straight line.
→ x + (x - 28) = 90
→ 2x - 28 = 90
→ 2x = 90 + 28
→ 2x = 118
→ x = 59°
Then find value of y
Angle y, x, 90° lies on a straight line which sum ups to 180°
→ x + y + 90° = 180°
→ 59 + y + 90° = 180°
→ y = 180° - 149°
→ y = 31°

Answer:
2q + 6
Step-by-step explanation:
To simplify, we will use the distributive property.
-(2q + 6) simplifies to -2q - 6 (In this case we are distributing the - sign or -1)
3(2q + 4) simplifies to 6q + 12
So if we recombine: -2q - 6 + 6q + 12 - 2q

-2q + -2q + 6q = 2q
-6 + 12 = 6
