Which equation is written in slope-intercpet form and has a slope of -5 and a y intercept of 5?

Answer:

To determine whether (1, 5) is a solution of a given system, you need to substitute these values into the equations of the system and check whether the resulting statements are true.

For example, if the given system is represented by the equations y = 2x + 1 and y = x - 3, then you would substitute 1 for x and 5 for y in each equation and check whether the resulting statements are true.

Substituting these values into the first equation, we get:

5 = 2(1) + 1

5 = 2 + 1

5 = 3

This statement is not true, so (1, 5) is not a solution of this system.

On the other hand, if the given system is represented by the equations y = 2x + 1 and y = 5, then substituting the values (1, 5) into both equations would result in true statements, so (1, 5) would be a solution of this system.

Step-by-step explanation:

a local winery bottles 14 different white wines. to help customers with their purchasing choice, the winery offers customers 5 white wine tasting samples free of charge 2002 many ways does a customer have to choose 5 different white wines to taste, using the concept of combination formula.

The number of possible ways to choose items from a collection when the order of choice is irrelevant is determined using the combination formula. Combination, to put it simply, is the process of choosing items or things from a bigger group where order is irrelevant.

The combination formula is: n! / (n-r)! r! , where n is the total number of items (14 in this case) and r is the number of items being selected at once (5 in this case),

Plugging our numbers into the formula we get:

= 14! / (14-5)! 5!

= 2002

After simplifying, we get 2002.

So, there are 2002 ways of picking 5 different white wines to taste from a group of 14 local winery bottles.

Answer:

  a)  y = 16/x²

  b)  x = 4/5

Step-by-step explanation:

You want the equation for y in terms of x when y is inversely proportional to the square of x, and y is 16 when x is 1. Further, you want the value of x when y is 25.

The wording "inversely proportional to the square" means the form of the equation is ...

  y = k/x² . . . . . . where k is the constant of proportionality

The value of k can be found from the given (x, y) pair.

  k = x²y = (1)²(16) = 16

The equation is ...

  y = 16/x²

Solving for x gives ...

  x = √(16/y)

Then the value of x for y = 25 is ...

  x = √(16/25)

  x = 4/5

Step-by-step explanation:

6*(60/15) = 1.5 (milles)

9*(60/40) = 13.5 (milles)

1.5 + 13.5 = 15 (milles)

15 / (45/60) = 20 (milles per hour)

The speed of Amy is 8.6 mph.

Speed is defined as the rate of change of distance with time. It has the dimension of distance by time. Thus, the SI unit of speed is given as the combination of the basic unit of distance and the basic unit of Time. Thus, the SI unit of speed is metre per second.

Given that, Jessica runs for 15 minutes at an average speed of 6 miles per hour. She then runs for 40 minutes at an average speed of 9 miles per hour. It takes Amy 45 minutes to run the same total distance that Jessica runs.

Calculating the distance covered by Jessica,

15 minutes = 0.25 hours

Speed = distance / time

Distance = speed × time

Distance = 0.25 × 6 = 1.5 mile

And,

40 minutes = 2/3 hours

Distance = 2/3 × 9 = 6 miles

Total distance covered by Jessica = 1.5+6 = 6.5 miles

Since, Amy covers the same distance in 45 minutes,

Therefore, 45 minutes = 3/4 hours

Speed = 6.5/0.75 = 8.6 mph

Hence, The speed of Amy is 8.6 mph.

Answer:

x = [tex]\frac{20}{7}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] x - 5= [tex]\frac{1}{2}[/tex] x + 2x - 10

multiply through by 4 ( the LCM of 4 and 2 ) to clear the fractions

3x - 20 = 2x + 8x - 40

3x - 20 = 10x - 40 ( subtract 10x from both sides )

- 7x - 20 = - 40 ( add 20 to both sides )

- 7x = - 20 ( divide both sides by - 7 )

x = [tex]\frac{-20}{-7}[/tex] = [tex]\frac{20}{7}[/tex]

Answer:

[tex]x=\frac{20}{7}[/tex]

Step-by-step explanation:

Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

[tex]\frac{1}{2}x+2x-10=\frac{3}{4}x-5[/tex]

Simplify the left side of the equation by combing [tex]\frac{1}{2}[/tex] and [tex]x[/tex].

[tex]\frac{x}{2}+2x-10=\frac{3}{4}x-5[/tex]

To write [tex]2x[/tex] as a fraction with a common denominator, multiply by [tex]\frac{2}{2}[/tex].

[tex]\frac{x}{2}+2x*\frac{2}{2} -10=\frac{3}{4}x-5[/tex]

Simplify terms by combining [tex]2x[/tex] and [tex]\frac{2}{2}[/tex]. Combine the numerators over the common denominator.

[tex]\frac{x+2x*2}{2} -10=\frac{3}{4}x-5[/tex]

Raise x to the power of 1.

[tex]\frac{x^1+2x*2}{2} -10=\frac{3}{4}x-5[/tex]

Factor [tex]x[/tex] out of [tex]x^1[/tex].

[tex]\frac{x*1+2x*2}{2} -10=\frac{3}{4}x-5[/tex]

Factor [tex]x[/tex] out of [tex]x+2x*2[/tex].

[tex]\frac{x*1+x(2*2)}{2} -10=\frac{3}{4}x-5[/tex]

Factor [tex]x[/tex] out of [tex]x*1+x(2*2)[/tex]

[tex]\frac{x(1+2*2)}{2} -10=\frac{3}{4}x-5[/tex]

Multiply 2 by 2.

[tex]\frac{x(1+4)}{2} -10=\frac{3}{4}x-5[/tex]

Add 1 and 4.

[tex]\frac{5x}{2} -10=\frac{3}{4}x-5[/tex]

Combine [tex]\frac{3}{4}[/tex] and [tex]x[/tex].

[tex]\frac{5x}{2} -10=\frac{3x}{4}-5[/tex]

Move all terms containing [tex]x[/tex] to the left side of the equation.

[tex]\frac{7x}{4}-10=-5[/tex]

Move all terms not containing [tex]x[/tex] to the right side of the equation.

[tex]\frac{7x}{4}=5[/tex]

Multiply both sides of the equation by [tex]\frac{4}{7}[/tex]

[tex]\frac{7x}{4}*\frac{4}{7} =5*\frac{4}{7}[/tex]

Answer:

The slope of the perpendicular line is -2.

Step-by-step explanation:

A perpendicular line has a slope that is the negative inverse of the slope of the reference line.  The reference line in this problem is 3x-6y=144.

Let's rearrange this equation to standard slope-intercept form of y=mx+b, where m is the slope and b is the y-intercept (the valuue of y when x=0).

3x-6y=144

-6y=144-3x

-6y=-3x + 144

 y = (3/6)x + (144/-6)

 y = (1/2)x - 24

This line has a slope of (1/2) and a y-intercept of -24.  A line perpendicular to this will have a slope that is the negative inverse of (1/2).  This would be -2.  The new line will take form:

 y = -2x + b

We are not given b, and there is not enough information to calculate one, so let's assume a value of -24, so that it intersects the original line at (0, -24).  See the attached graph.

The possible coordinates of point A such that the distance to point B is 10 units are:

(-5, -4) and (-5, 8)

We know that the distance between two points (a, b) and (c, d) is:

distance = √( (a - c)² + (b - d)²)

In this case, we know that:

B = (3, 2)

A = (-5, y)

And the distance is 10 units, then we can write:

10 = √( (3 + 5)² + (2 - y)²)

10² = 8² + (2 - y)²

100 - 64 =  (2 - y)²

36 =  (2 - y)²

±√36 = 2 - y

±6 = 2 - y

y=n-3^2 is linear

Step-by-step explanation:

A linear equation is an equation between two variables that give a straight line with plotted on a graph.

The two variables used are "n" and "3^2"

When graphed, it forms a diagonal, straight line.

Check the picture below.

A rectangle is constructed on a semicircle so that the length equals the diameter. The width of the rectangle is approximately 10.65 inches.

Generally, Let the width of the rectangle be x. Then the length of the rectangle is 3x.

The diameter of the semicircle is also the length of the rectangle, so it is 3x.

The area of the rectangle is x*(3x) = 3x^2. The area of the semicircle is (1/2)πr^2, where r is the radius of the semicircle. Since the diameter of the semicircle is 3x, the radius is (3x)/2. The area of the semicircle is (1/2)π((3x)/2)^2 = (9/8)πx^2.

The total area of the figure is the sum of the area of the rectangle and the area of the semicircle. We can set up the equation:

3x^2 + (9/8)πx^2 = 750

(21/8)πx^2 = 750

x^2 = 750/(21/8)*π

x = √(750/(21/8)*π)

To find the approximate dimensions of the rectangle, we can use the fact that pi is approximately 3.14. This gives us:

x = √(750/(21/8)*3.14)

= √(750/6.71)

= √(112.64)

= approximately 10.65 inches.

The width of the rectangle is approximately 10.65 inches. The length of the rectangle is 3 times the width, so it is approximately 31.95 inches.
