help please, i don't know what to do for b. I've did a which is -2
Answer:
y=-2x+6
Step-by-step explanation:
So you know the perpendicular gradient is -2 so the equation so far is y=-2x+?
Find the midpoint of AB which is:
(3,0)
Using this, plug it into the equation you've formed:
0= -6 + ?
? = 6
So the equation of the perpendicular line is y=-2x+6

A. 112
B. 98
C. 84
D. 28
The information given in the triangle shows that the total distance from A to B to C to D to E will be C. 84.
How to calculate the triangle?From the information given, ABF = EDG, GCF are equilateral and AG = 21 while CG = 1/4.
The total distance from A to B to C to D to E will be:
= 21/CG
= 21 / 1/4
= 21/0.25
= 84
In conclusion, the correct option is 84.

What is an Outlier in a Dataset?Outlier in a data set is simply the extremely low data point or an extremely high data point compared to other points in the dataset.
It will stand out from the other values in the dataset.
Given a dot plot which represents the height in inches of the Deep Purple Gymnastics Team members.
Only mean and range is affected by the outlier, median will not, since the middle value of the data set remains the same even if the end values are changed.
Here outlier is at the lowest end, which is 60.
Mean is the average of the data points. Since the outlier is at the low end, mean decreases.
Median stays the same.
Range is the difference of maximum and the minimum value. Range increases since the minimum value is lower.
Hence the mean decreases, median stays the same and range increases.

So the Answer will be D.
Step-by-step explanation:
Cuz if you look it up online it will give you words or maybe links that youu shouldn't look at cuz they don't really give it to you. It shows that ''A rotation turns each point on the preimage a given angle measure around a fixed point or axis. Each point on triangle ABC is rotated 45° counterclockwise around point R, the center of rotation, to form triangle DEF.'' So indee that D. is right. (I am only 11 and i am helping lol)

The diagram is a floor plan for a new building. Find the perimeter.
Answer:
154
Step-by-step explanation:
the perimeter is the summation of all the sides of the plane. so
15 + 14 + 20 + 9 + 15 + 13 + 50 + 18 = 154
i think this is ✅
Using the labelled size of segments, the perimeter of the given figure is 154 units. Hence, the fourth option is true.
Use the concept of perimeter defined as:
The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges.
According to the figure,
The perimeter of the given building is the sum of the lengths shown in the figure.
18 + 15 + 14 + 20 + 9 + 15 + 13 + 50 = 154.
Hence,
The required perimeter is 154 units, which is option fourth.

Find the value f x,
[tex]7x-\left(x-12\right)=32-4x[/tex]
Answer:
x = 2.
Step-by-step explanation:
7x - (x - 12) = 32 - 4x Distributing the negative over the parentheses:-
7x - x + 12 = 32 - 4x Bringing like terms together:-
7x - x + 4x = 32 - 12 Simpifying:
10x = 20
x = 2.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
In order to solve for the variable [tex]x[/tex], simply move all terms with the variable to one side and all constants to the other. [tex]7x-(x-12)=32-4x[/tex] => [tex]7x-x+12=32-4x[/tex] => [tex]6x+12=32-4x[/tex] => [tex]10x=20[/tex] => [tex]x=2[/tex].
You can check this answer by plugging it back into the equation as a substitute for the variable. [tex]7(2)-(2-12)=32-4(8)[/tex] => [tex]14-(-10)=32-8[/tex] => [tex]24=24[/tex], since the equation is true, this proves that x = 2 is the correct answer.

The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.
What is multiplication?It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expressions are 2i and (4 – 5i).
Then the product of the expression will be given as
2i (4 – 5i)
8i – 10i²
And we know that i² = -1
Then we have
