Solve the equation
9(k - 2) = -6
what is k?
Answer:
k= 4/3
Step-by-step explanation:
distribute 9 9k- 18=-6
add 18 to both sides 9k= 12
divide by 9
The value of k is 4/3 or 1.334.
What is Equation?A statement that supports the equality of two expressions that are connected by the equals sign "=" is an equation.
An equation is a condition on a variable in algebra. It only holds true for a specific value of the variable.
Polynomial equations and linear equations are two prominent families of equations that algebra takes into account.
Given equation
9(k - 2) = -6
9k - 18 = -6
add 18 both sides
9k - 18 + 18 = -6 + 18
9k = 12
k = 12/9 =4/3 = 1.334
Hence the value of k is 4/3 or 1.334.

Rotate the vector (5,1) 90°
clockwise about the origin.
Answer:
(-1, 5)
Step-by-step explanation:
this is correct
The new coordinates of the vector (5,1) after rotating it 90° clockwise about the origin would be (-1,5).
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
Rotating a vector 90° clockwise in a 2D coordinate system can be accomplished by "flipping" the vector's x and y coordinates and then negating one of them.
In this case, the original x-coordinate is 5 and the y-coordinate is 1.
When we negate the x-coordinate and swap the positions of x and y, we get the new coordinates of (-1,5).

The graph of an absolute value function contains the points (1, 2), (0, 0), and (–1, 2). Shawn thinks the function this graph represents is f(x) = 2|–x|. Brielle thinks the function this graph represents is f(x) = 2|x|. Determine who is correct and explain why.
Answer:
Shawn and Brielle are correct, since absolute has the following property: [tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]
Step-by-step explanation:
Both Shawn and Brielle are correct, because the absolute value has the following property:
[tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]
Which means that [tex]|x|[/tex] and [tex]|-x|[/tex] gives the same result.
Answer:
Both Shawn and Brielle are correct. The absolute value parent function is symmetric with respect to the y-axis, and the absolute value of negative x is a reflection across the y-axis, so the graph of these two functions would look identical. Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

Answer:

Step-by-step explanation:
This I am pretty sure on.
The only side you can 100% say is similar is DE. since it is the same line.
The angles GDE and FDE are the same since there is a line divivding it in half.
All other answers use two or more sides, unless marked with a little dash, indicating that they are the same size, you really can't use those side.

Answer:
Angle C is 54 degrees
Step-by-step explanation:
Angle B is 67 degrees and Angle A is 59 degrees. You add those two together to get 126 and subtract that from 180 to get the measure of Angle C
The measure of angle C is 54°.
From the diagram given, triangle A'B'C is a reflection of triangle ABC, therefore, triangle A'B'C' is similar to triangle ABC.
This implies that:angle A = angle A' = 59°
angle B = angle B' = 67°
angle C = angle C' = ?
Therefore,angle C = 180 - (angle A + angle B) ---> Sum of angles in a triangle equals 180°.
Plug in the valuesangle C = [tex]180 - (59 + 67)\\[/tex]
angle C = 54°
Therefore, the measure of angle C is 54°.

1.) Given : S is the midpoint of RT; PR = PT
Prove : PRS = PTS
2.) Given : E is the midpoint of AB and CD
Prove: AEC=BED
Answer: 1.
Given: S is the midpoint of RT
PR=PT
To Prove: PRS=PTS
Step-by-step explanation:
If PR=PT in a triangle PRT, then the triangle is isosceles triangle.
Therefore, ∠PRT=∠PTR (opposite angles of an isosceles triangle are equal)
In ▲PRS and ▲PTS
PR=PT
∠PRT=∠PTR
PS=PS (PS is common)
therefore, ▲PRS≅▲PTS
Therefore, ∠PRS=∠PTS
Hence proved.
Answer: 2.
Given: E is the midpoint of AB and CD.
To Prove: AEC=BED
Step-by-step explanation:
If AB and CD are the diagonals of rectangle, then
diagonals AB=CD, sides AC=BD and AD=BC
In ▲AEC and ▲BED,
∠AEC=∠BED(vertically opposite angles)
AE=BE
AC=BD
therefore, ▲AEC≅▲BED
Therefore, ∠AEC=∠BED
Hence Proved.
The proofing of each part should be explained below.
Prove:a.
In the case when
PR=PT in a triangle PRT,
So the triangle is an isosceles triangle.
Therefore, ∠PRT=∠PTR
Now
In ΔPRS and ΔPTS
PR=PT
So,
∠PRT=∠PTR
So,
PS=PS (PS is common)
ΔPRS≅ΔPTS
Hence proved.
2.
In the case when AB and CD are the diagonals of the rectangle,
So,
diagonals AB=CD, sides AC=BD and AD=BC
In ΔAEC and ΔBED,
So,
∠AEC=∠BED
That means
AE=BE
AC=BD
therefore, ΔAEC≅ΔBED
Hence Proved.
