Answer:

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.

Answer:

E(-2, -1.5)

Step-by-step explanation:

Coordinates of the points C and D:

C(1, 6), D(-3, -4)

The point E has coordinates of (x, y).

The point E is at 3/4 of CD from C and 1/4 of CD from the point D.

Find coordinates of E:

x = -3 + 1/4(1 + 3) = -3 + 1 = -2
y = -4 + 1/4(6 + 4) = -4 + 2.5 = -1.5

. Which category(s) does 75% belong? I. Real II. Whole III.Rational IV. Integer V. Irrational VI. Natural * A. III and IV only B

kifflom [539]

Answer: B.) 1 and 111 only.

Step-by-step explanation:

75% = 75/100 = 0.75

0.75 falls into the category of rational numbers. Rational numbers comprises of numbers which can be expressed in the form a/b where a and b are integers and B is not 0. Here, both 75 and 100 are integers, thus 75% is a rational number.

Irrational numbers are the opposite of rational numbers thus, 75% is not irrational.

All rational numbers and irrational numbers are REAL numbers, hence, 75% is a real number.

Natural numbers are whole digits starting from 1 e.g ( 1, 2, 3,......). Hence 75% is not a natural number

Whole numbers are natural numbers including 0. (0, 1, 2,.....). Hence, 75% is not a whole number

Integer numbers are comprises of both positive and negative whole numbers. (..., - 1, - 2, 0, 1, 2,...). Hence, 75% is not an integer.
