Claire correctly solved the proportion StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction for x by using cross products to get the equation 16 x = 144 and then dividing both sides by 16 to get x = 9. She showed that she can use cross products to solve the proportion because she gets the same answer if the solves it as shown.


StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction. StartFraction x over 4 EndFraction times 4 = StartFraction 36 over 16 EndFraction times 4. x = StartFraction 144 over 16 EndFraction. X = 9.

What property allowed her to go from StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction to StartFraction x over 4 EndFraction times 4 = StartFraction 36 over 16 EndFraction times 4 ?

Answers

Answer 1

Answer:

The property used here is: Multiplication property of Equality

Step-by-step explanation:

Claire solved the expression [tex]\frac{x}{4}=\frac{36}{16}[/tex] by two ways

Way 1: Solving using proportion:

[tex]\frac{x}{4}=\frac{36}{16}[/tex]

By cross multiplying:

[tex]16x=144[/tex]

Divide both sides by 16

[tex]x=9[/tex]

Way 2:

She also solve the same expression [tex]\frac{x}{4}=\frac{36}{16}[/tex] by using following steps

Multiply both sides by 4

[tex]4\times( \frac{x}{4})=4\times(\frac{36}{16})\\x=\frac{144}{16}\\x=9[/tex]

We need to tell the name of property that allowed her to go from [tex]\frac{x}{4}=\frac{36}{16}[/tex] to [tex]4\times(\frac{x}{4})=4\times(\frac{36}{16})[/tex]

The property used here is: Multiplication property of Equality

The property states that if A , B and C are real numbers then

A = B and AC = BC are equivalent.

We will use the KFC method to figure out the answer:

3/5 ÷ 2/1

We keep the first fraction

3/5 ÷ 2/1

Flip the last fraction (swap the numbers)

3/5 ÷ 1/2

Change the sign (to a multiplication symbol)

3/5 x 1/2

Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).

3 x 1 = 3

5 x 2 = 10

The answer is 3/10 because it cannot be simplified any further.

The range of function g is (3, infinity) .
Function g is positive over the interval (negative infinity, infinity) .

Answers

Answer:

A,B,D,E

Step-by-step explanation:

The statements which are true shown below,

Function g is 4 units above function f.Function g has a y-intercept of (0,4)The range of function g is (3, ∞).Function g is positive over the interval (-∞ , ∞ ).

From graph attached below, It is observed that

Graph of function g is 4 units above the graph of parent exponential function.Domain of the function is defined as all the input values for which function is defined. From graph of function g, the domain of function is (-∞ , ∞ )The y- intercept is the point at which graph of function crosses the y-axis. Graph of function g crosses y-axis at (0, 4). Therefore, Function g has a y-intercept of (0,4).Function g increasing over the interval (-∞, 0) .Range of function is known as output values of function. From graph, it is observed that the range of function g is (3, ∞).Since, graph of function g is above x- axis. Therefore, Function g is positive over the interval (-∞ , ∞ ).
