Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin
The inequality 4(x – 3) + 4 < 10 + 6x is solved as x > -9. Then the variable x is greater than the negative 9. Then the correct option is B.
<h3>What is inequality?</h3>
Inequality is defined as an equation that does not contain an equal sign.
The inequality equation is given below.
4(x – 3) + 4 < 10 + 6x
Then the steps of solving are given below.
1. The distributive property: 4x – 12 + 4 < 10 + 6x
2. Combine like terms: 4x – 8 < 10 + 6x
3. The addition property of inequality: 4x < 18 + 6x
4. The subtraction property of inequality: –2x < 18
5. The division property of inequality: x > –9
Then x is greater than the negative 9.
Then the correct option is B.

Answer:
53
Step-by-step explanation:
Take the mean of each row in the accidents reported column so for example 0-4 would be 0+4/2 = 2
Then times it by the frequency which in this case is 15:
2 x 15 = 30
Do this for each rows and then add it all up:
30 + 28 + 120 + 34 = 212
Then divide it by number of row which in this case is 4:
212/4 = 53
