Select proportional or not proportional to correctly classify the pair of ratios. 1.2/3 and 1.8/4.5
Gnesinka [82]

Answer:

Proportional.

Step-by-step explanation:

Find the cross products. If they are same, then they are proportional.

\dfrac{1.2}{3} = \dfrac{1.8}{4.5}

Cross multiply,

1.2 * 4 .5       =         3*1.8

      5.40      = 5.4

So, they are proportional.

Or

Multiply the numerator and denominator of 1.2/3 by 1.5

\dfrac{1.2*1.5}{3*1.5}=\dfrac{1.8}{4.5}

From this we come to know they are proportional

Or

1.2 : 3 :: 1.8 : 4.5

Product of means = 3*1.8 = 5.4

Product of extremes = 1.2*4.5 = 5.4

Product of means = product of extremes. So, they are proportional.

What are the domain and range of the function represented by the set of ordered pairs? \ (-6,5),(-3,2),(-1,0),(5,-4)\
stellarik [79]

Answer:

The domain and the range of the function represented by the set of ordered pairs are {-6, -3, -1, 5} and {5, 2, 0, -4}

Step-by-step explanation:

In any set of ordered pairs,

  • The domain is the values of x (set of x) ⇒ the first number in each ordered pair
  • The range is the value of y (set of y) ⇒ the second number in each ordered pair

Let us solve the question

∵ The set of ordered pairs is {(-6, 5), (-3, 2), (-1, 0), (5, -4)}

∵ The first number in each ordered pair represents x

∴ x = -6, -3, -1, 5

∵ The set of x is the domain of the function

∴ The domain of the set of ordered pairs = {-6, -3, -1, 5}

∵ The second number in each ordered pair represents y

∴ y = 5, 2, 0, -4

∵ The set of y is the range of the function

∴ The range of the set of ordered pairs = {5, 2, 0, -4}

The domain and the range of the function represented by the set of ordered pairs are {-6, -3, -1, 5} and {5, 2, 0, -4}
