Answers

Answer:

6.75

Step-by-step explanation:

We are given that function

[tex]f(x)=\frac{9x-18}{4}[/tex]

5 is an element in the domain of f(x)

i.e

x=5

We have to find the corresponding element of 5 in the range of f(x).

Substitute x=5 in the given function

[tex]f(5)=\frac{9\times 5-18}{4}[/tex]

[tex]f(5)=6.75[/tex]

Hence, the corresponding element of 5 is 6.75 in the range.

Answers

Answer:

Let's solve your equation step-by-step.

27+9x=12x−6

Step 1: Simplify both sides of the equation.

27+9x=12x−6

27+9x=12x+−6

9x+27=12x−6

Step 2: Subtract 12x from both sides.

9x+27−12x=12x−6−12x

−3x+27=−6

Step 3: Subtract 27 from both sides.

−3x+27−27=−6−27

−3x=−33

Step 4: Divide both sides by -3.

−3x

−3

Answer:

x = 23.33333

y = 35

Step-by-step explanation:

3x+2y=70

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000

y-intercept = 70/2 = 35

Calculate the X-Intercept :

When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333

x-intercept = 70/3 = 23.33333

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -3.000/2.000 = -1.500

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

this is Solving Proportions

Answers

Answer:

Step-by-step explanation:

3 is to 8 as x is to 32

3/8=x/32

x=12

The number of dimes cannot be 10 because the number of dimes in the jar will be equal to 12.

What is the ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.

As per the data in the question,

The ratio of Dimes to pennies: 3 : 8

Number of Pennies in jar = 32

Assume that the number of Dimes in the jar is x.

So, the number of dimes will be,

x = (32 × 3)/8

x = 12 Dimes.
