Answer:

Each of the domain values, x, should only output a single unique range value, y.

This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.

-1 outputs a 3

and

-1 outputs a 5

If I were to draw a vertical line at the domain value of -1 that vertical line would intersect the points (-1,3) and (-1,5). Which indicates that the relation

The value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

The expression is given as:

3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two

Rewrite properly as:

[3² * 3⁻⁵]/[5⁻²]

Apply the negative exponent law of indices

So, we have

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3⁻² * 3⁵]

Apply the exponent law of indices

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3³]

This gives

[3² * 3⁻⁵]/[5⁻²] = 25/27

Hence, the value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

Answer:

Step-by-step explanation:

You want an inequality to determine how many miles eddie can travel if he has $15 to spend on a taxicab that charges $1.75 for the flat fee and $0.25 for each mile.

The mileage charge is the per-mile charge ($0.25) multiplied by the number of miles (m). It will be $0.25m.

The total charge is the mileage charge plus the flat fee. Eddie wants that to be no greater than $15.

  1.75 +0.25m ≤ 15

We can solve this inequality in 2 steps.

  0.25m = 13.25 . . . . . subtract 1.75

  m = 53 . . . . . . . . . . . divide by 0.25 (or multiply by 4)

Eddie can travel 53 miles if he has $15 to spend.

Step-by-step explanation:

Answer:

x = 3, y = 1

Step-by-step explanation:

Given the 2 equations

2x + y = 7 → (1)

3x - 4y = 5 → (2)

Multiplying (1) by 4 and adding to (2) will eliminate the y- term

8x + 4y = 28 → (3)

Add (2) and (3) term by term to eliminate y

11x = 33 ( divide both sides by 11 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

2(3) + y = 7

6 + y = 7 ( subtract 6 from both sides )

y = 1

solution is x = 3 and y = 1

Answer:

It will take him 1 hour 35 minutes to finish a 10 mile race

Answer is (C)

Cody runs 10-mile in 1 hour 35 minutes.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Cody runs 4 miles in 38 minutes.

Now,

Since, Cody runs 4 miles in 38 minutes.

Hence, The time to run 10 miles = 38 × 10 / 4

                                                  = 380/4

                                                  = 95 minutes

                                                  = 1 hour 35 minutes

Thus, Cody runs 10-mile in 1 hour 35 minutes.

Step-by-step explanation:

The area of the window is [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]

The shape of the Norman window is described as a rectangle surmounted by a semicircle.

Let 'x' be the width of the window.

Then this width corresponds to the diameter of the semicircle.

That is, radius of the semicircle = x/2

Now given the perimeter of the whole window = 25 ft

This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.

Perimeter of the semicircle = [tex]\frac{2\pi r}{2} = \frac{\pi x}{2}[/tex] , where r is the radius of the semicircle.

Now let 'y' be the length of the window.

Then sum of three sides of the window = 2y + x

So 2y + x + [tex]\frac{\pi x}{2}[/tex] = 25

Therefore, [tex]y =( 25 - x - \frac{\pi x}{2} ) / 2[/tex]

Area of the window = Area of the semicircle + Area of the rectangle =

 [tex]\frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2[/tex]

 So Area of the window = [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]

Since there are 3 x's in the graphic, we have to think what times 3 is 24? The answer to that is 8!

The value of x in the diagram is 8.

A tape diagram is a rectangular visual model that resembles a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction, and commonly multiplication.

It is also known as a divided bar model, fraction strip, length model or strip diagram.

From the diagram, you will notice that:

x + x + x = 24

Add the three x:

3x = 24

Divide both sides by 3:

x = 24/3

x = 8

Thus, the value of x is 8.

Explanation:

Of your original given list, let's write down the parallelograms. They are:

So we cross those off the list since we want a quadrilateral with no sides parallel. A parallelogram, by definition, is a quadrilateral with both pairs of opposite sides that are parallel.

We can also rule out the trapezoids because a trapezoid is a four sided figure (quadrilateral) where we have exactly 1 pair of parallel sides, while the other sides are not parallel.

Lastly, we can rule out the kite because any kite has perpendicular diagonals.

The only thing left is quadrilateral. In my opinion this answer should be more specific and say "quadrilateral that isn't a parallelogram, a trapezoid, or a kite", but I think I see what your teacher was going for here.

Here is the correct order of the step:

Identify: Anna's time is the unknown

Strategize : let x = Anna's time

Set up : 7(40) = x(50)

Solve: x = 5.6

Check: 7(40) = 5.6(50)

The first step is to determine the distance Allen travelled:

Distance = average speed x time

40 x 7 = 280 miles  

The second step is to determine the time it took Anna to travel 280 miles.

Time = distance / average speed
