Answer:

Freddie would have walked 25 miles after 12 and a half hours.

Step-by-step explanation:

Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:

4/2 = Miles per hour

2 miles per hour

2X = Y

2X = 25

X = 25/2

X = 12.5

Therefore, Freddie would have walked 25 miles after 12 and a half hours.

Step-by-step explanation:

Equation of line in point-slope form is

[tex]y-y_1 = m(x-x_1)[/tex]

Here

[tex]m=6 \ \ \ and \ \ \ (x_1, y_1) = (2, 7)[/tex]

Substituting values in equation

[tex]y-7=6(x-2)[/tex]

Answer:

1.62

Step-by-step explanation:

smaller number: y

x - y = 1        x = y+1

xy = 1

(y + 1) * y = 1

y² + y - 1 = 0

y = (-1 ± √(1² - 4 * 1 * -1)) / 2 = (-1 ± √5) / 2

small number: (-1 - √5) / 2 = - 1.62

Graph A

Step-by-step explanation:

Based on the inequality shown, you know that the graphed line needs to be both solid and must be shaded above. This is because of the equal to or greater than sign that points toward the y. So, from that you can cancel out b and c because neither are shaded above the line. Then, you can further cancel out d because it has a dashed and not solid line.

Step-by-step explanation:

I believe the sale price for the chair would be 134.56 hope this helps

Answer:

$ 134.56

Step-by-step explanation:

Regular price = $175 .90

Reduction = 10% of 175.90

                 = 17.59

Price after reduction = 175.90 - 17.59 = $ 158.31

Second reduction = 15% of 158.31

                             = 0.15 * 158.31

                             = 23.7465

                             = $ 23.75

New price = 158.31 - 23.75

                  = $ 134.56

Answer:

12 cows - 48 legs

4 ducks- 8 legs

- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.

Step-by-step explanation:

22 total animals

56 total legs

ducks have 2 legs

cows have 4 legs

12 times 4 = 48 ( 12 cows with 4 legs each cow =  48 legs)

4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)

Creating a system of equation using the scenario described, the number of cows and ducks owned are 6 and 16 respectively.

The equation goes thus :

c + d = 22 - - - (1)

4c + 2d = 56 - - - (2)

From (1)

c = 22 - d - - - - (3)

Substitute (3) into (2)

4(22 - d) + 2d = 56

88 - 4d + 2d = 56

88 - 2d = 56

-2d = 56 - 88

-2d = - 32

d = 16

From (3)

c = 22 - 16

c = 6

Hence, the number of cows and ducks owned are 6 and 16 respectively.

Answer:

The translation is 1  unit to the left and  5 units down

Step-by-step explanation:

The explanation is given below;

Given that

The transform function is [tex]f(x) = \sqrt{x+1} - 5[/tex]

It can be seen that

The parent function is

[tex]f(x) = \sqrt{x}[/tex]

After that

The parent function would be transform 1 units to the left [tex]\sqrt{x+1}[/tex]

And afterwards it would be transform in 5 units down [tex]\sqrt{x+1} - 5[/tex]

So

The parent function [tex]f(x) = \sqrt{x}[/tex] would be  translate in 1  unit to the left and  5 units down

Step-by-step explanation:

If a line is perpendicular to a circle's radius at its outer endpoint, then the line is _Tangent_ to that circle.

A line segment which touches a circle specified to only one point is called a tangent to that circle.

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

If there is circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.

We need to find the if a line is perpendicular to a circle's radius at its outer endpoint, then the line is _____(what) to that circle.

If a line is perpendicular to a circle's radius at its outer endpoint, then the line is _Tangent_ to that circle.
