In quadrilateral HJKL shown below, point J can be mapped to point K by a 46 counterclockwise rotation about point H, and point K can be mapped to point L by a 72 counterclockwise rotation about point H.
Explain why HJ must be congruent to HL.
Determine the measure of HJL
By transitive property, HJ is congruent to HL.
Measure of ∠HJL = 31°
What is quadrilateral?A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles.
There are two types of quadrilateral : concave quadrilateral and convex quadrilateral.
Convex quadrilaterals are then sub-categorized to quadrilaterals like trapezoid, parallelogram, rectangle, rhombus, and square.
Given,
In quadrilateral HJKL,
Point J can be mapped to point K by a 46° counterclockwise rotation about point H.
So, ∠JHK = 46°
and HJ = HK --------(1)
point K can be mapped to point L by a 72 counterclockwise rotation about point H.
So, ∠KHL = 72°
and HK = HL --------(2)
By equation (1) and (2), applying transitive property
HJ = HL
Now, in triangle JHL
HJ = HL
Angles in a triangle are equal if opposite sides to them are equal
∴ ∠HJL = ∠HLJ
Sum of interior angles of a triangle is equal to 180°
∠HJL + ∠HLJ + ∠JHL = 180°
∠HJL + ∠HJL + ∠JHK + ∠KHL = 180°
2∠HJL + 46° + 72° = 180°
2∠HJL = 180° - 118°
2∠HJL = 62°
∠HJL = 31°
Hence, by the calculation HJ is congruent to HL
and 31° is measure of ∠HJL.

Angle STV is a straight angle the measure of angle STW is 125 the measure of angle WTV is X what is the value of X
Answer:
x = 55°
Step-by-step explanation:
If ∡STV is a straight angle (or 180°) and ∡STW is 125°, then we can assume that the angles look something like this
V | / W
| /
| x° /
T | /
| 125°
|
S |
Now this means that to get ∡WTV, we need to subtract ∡STW from ∡STV, which would look like this:
180 - 125 = 55
This means ∡WTV (or x) = 55°
Which graph represents y as a function of x?

The last one is the answer.

i don’t know can someone help
Answer:
x = -13
Step-by-step explanation:
Equation:
(6x+8)/7 = -10
Multiply both sides by 7:
7* (6x+8)/7 = -10*7
6x+8 = -70
Subtract both sides by 8:
6x + 8 - 8 = -70 - 8
6x = -78
Divide both sides by 6:
6x/6 = -78/6
x = -13
Check answer:
(6*(-13) + 8)/7 = -10
(-78 + 8)/7 = -10
(-70)/7 = -10
-10 = -10
Our answer is correct :)
Answer:

A number is 8 less than 5 times the same number.
Write this item into an algebraic expression or equation.
A number x is 8 less than 5 times the same number x. This means that :
x +8= 5x
We can also write :
5x = x +8
5x - x = x + 8 - x
4x = 8
4x / 4 = 8 / 4
x = 2
CAN SOMEONE HELP ME!!!
Answer:
g(x) = 0.5(0.8)^x + 2.
Step-by-step explanation:
At large positive values the required function needs to tend to the value 2, so that excludes the 2 middle functions.
The function is also decreasing so the value in the parentheses must be < 1,
so it must be the last function.

Write an equation of the line that passes through (2, -1) and (-3, 3). help please
Answer:
[tex]y=-\displaystyle\frac{4}{5}x+\displaystyle\frac{3}{5}[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis).
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (2, -1) and (-3, 3):
[tex]m=\displaystyle\frac{-1-3}{2-(-3)}\\\\m=\displaystyle\frac{-4}{2+3}\\\\m=-\displaystyle\frac{4}{5}[/tex]
Therefore, the slope of the line is [tex]-\displaystyle\frac{4}{5}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\displaystyle\frac{4}{5}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-\displaystyle\frac{4}{5}x+b[/tex]
Plug in one of the given points and solve for b:
[tex]-1=-\displaystyle\frac{4}{5}(2)+b\\\\-1=-\displaystyle\frac{8}{5}+b\\\\b=\displaystyle\frac{3}{5}[/tex]
Therefore, the y-intercept is [tex]\displaystyle\frac{3}{5}[/tex]. Plug this back into [tex]y=-\displaystyle\frac{4}{5}x+b[/tex]:
[tex]y=-\displaystyle\frac{4}{5}x+\displaystyle\frac{3}{5}[/tex]

Answer:
4x2 - 4x + 4.
Step-by-step explanation:
x2 - 3x - 4 - (x - 3x2 - 8) Distribute the negative over the parentheses:
= x2 - 3x - 4 - x + 3x2 + 8 Bring like terms together:
= x2 + 3x2 - 3x - x - 4 + 8
= 4x2 - 4x + 4.
