A. y=-2/3x-4/3
B. y= - 2/3x-10/3
C. y= -2/3x-2/3
D. y= -2/3x -17/4
Answer:
B: y = -2/3x - 10/3
Step-by-step explanation:
The point is at (-2,-2), therefore when you input -2 into the desired equation, it should yield -2 as our output. If we use the equation B, the equation becomes
-4/3 - 10/3 which is -6/3. After dividing it we get -2 as the output.
To find the line yourself we use the point slope formula
y - y1 = m(x - x1)
The line is parallel to the one on the graph so the slope or m is equal to -2/3
We input the coordinates we want for y1 and x1.
y - (-2) = -2/3 (x - (-2))
y + 2 = -2/3x - 4/3
y + 6/3 = -2/3x - 4/3
y = -2/3x - 10/3

In the diagram, △RST∼△R′S′T′ . Determine the length of RS¯¯¯¯¯¯¯ . Show your work on paper or in the box below.
The length of RS is such that △RST∼△R′S′T′ will be 6 feet.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Given two triangles are similar △RST∼△R′S′T′
If two triangles are similar then the ratio of the corresponding side must be the same.
Therefore,
RS/R'S' = TS/T'S'
(12x + 2)/(5x + 1) = 9/4
By cross multiplication,
48x + 8 = 45x + 9
3x = 1
x = 1/3
Therefore,RS = 12(1/3) + 2
⇒ 6 feet
Hence "The length of RS is such that △RST∼△R′S′T′ will be 6 feet".

Which figure below does not illustrate rotational symmetry?
Answer:
the answer is F
Step-by-step explanation:
The correct option is option F , that is figure F shows the rotational symmetry.
What is rotational symmetry ?
An object's ability to maintain the same shape when rotated about its own axis is known as rotational symmetry.
Some figures are given and we have to tell which figure doesn't illustrate rotational symmetry.
Let's check them all , one by one.
F)
We know that rotational symmetry meant a figure looks the same when it is rotated. Here , if we consider a point on the circle and try to rotate it about its own axis , then we get to know that the figure does not looks same in all directions.
So , this figure doesn't have rotational symmetry.
G)
This figure is when rotated about its own axis , we get that that it looks same in all directions. This figure has rotational symmetry.
H)
This figure also has rotational symmetry.
G)
We know that a triangle follows the rotational symmetry. If we rotate it , we get the same looks in all directions. This figure has the rotational symmetry.
Therefore , the correct option is option F , that is figure F shows the rotational symmetry.

What is the magnitude of the vector shown?

13
StartRoot 5 EndRoot
StartRoot 13 EndRoot
Answer:
D. sqrt 13
Step-by-step explanation:
took on edge :)
The required magnitude of the vector is √13. Option D is correct.
A graph is given, that shows the vector, the magnitude of the vector is to be determined.
Vector form is defined as representing any point in space that has both magnitude and direction. A point k in space is represented as a vector OKi + OKj, which denotes the vector line, OK joining the line from the origin O to the point k. The vector form is used to define a line or a plane in a 3D space.
From the figure,
given vector can be expressed as,
[tex]\bar v = 3\bar i+2\bar j[/tex]
now the magnitude of vactor,
[tex]|\bar v| = \sqrt{3^2+2^2}\\|\bar v| = \sqrt{9+4}\ \\|\bar v| = \sqrt{13}\[/tex]
Thus, the required magnitude of the vector is √13. Option D is correct.

A pond contains 20 tadpoles, of which f are frog tadpoles and the others are toad tadpoles. If 10 more frog tadpoles are added to the pond, the probability of catching a frog tadpole is doubled. Find f
Answer:
The value of f is 5
Step-by-step explanation:
Initially, the number of frog tadpoles = f
The initial probability of catching a frog tadpole = f/20
Adding 10 more frog tadpoles,
Number of frog Tadpoles = f +10
Total number of tadpoles in the pond = 20+10 = 30
new probability of catching a frog tadpole = (f+10)/30
New probability of catching a frog tadpole = 2 x Initial probability of catching a frog tadpole
(f+10)/30 = 2 x (f/20)
(f+10)/30 = f/10
f+10 = f x 30/10
f+10 = 3f
2f = 10
f = 5

3 |d + 1 |-7>= -1
I don’t know if it’s no solution or not
Answer: [tex]d \ge 1 \ \text{ or } \ d \le -3\\\\[/tex]
Both parts are needed to form the full solution set.
=============================================
Work Shown:
[tex]3|d+1|-7 \ge -1\\\\3|d+1| \ge 6\\\\|d+1| \ge 2\\\\d+1 \ge 2 \ \text{ or } \ d+1 \le -2\\\\d \ge 1 \ \text{ or } \ d \le -3\\\\[/tex]
In the second step, I added 7 to both sides. In the third step, I divided both sides by 3. Afterward, I used the rule that [tex]|x| \ge k[/tex] breaks down into [tex]x \ge k \ \text{ or } \ x \le -k[/tex] for some positive value k. The last thing to do is to subtract 1 from both sides to fully isolate d.
