Answer:

B. Square

Step-by-step explanation:

Finding the side lengths :

Side 1

⇒ d₁ = √(-4 - 0)² + (8 - 8)²

⇒ d₁ = √16

d₁ = 4

=============================================================

Side 2

⇒ d₂ = √(-4 + 4)² + (8 - 4)²

⇒ d₂ = √16

d₂ = 4

===========================================================

Side 3

⇒ d₃ = √(-4 - 0)² + (4 - 4)²

⇒ d₃ = √16

d₃ = 4

============================================================

Side 4

⇒ d₄ = √(0 - 0)² + (8 - 4)²

⇒ d₄ = √16

d₄ = 4

As all sides of the figure are equal, and it creates 4 right angles, it is a square.

Solvex - 5+ 7 = 15.
A. x = 13 and x = -3
-13 and x = 3
C. x = -13 and x = -3
OD. x = 13 and x = -13
OB. x =

Answers

Answer:

A. X= 13 and X= -3

Step-by-step explanation:

subtract 7 from both sides, simplify, break down the problems into 2 equations, solve equations, and boom once solve both equations you get 2 solutions.

The solutions to the equation are x = 13 and x = -3.

Therefore, the correct option is A.

Given is an expression |x-5| + 7 = 15, we need to solve for x,

To solve the equation |x - 5| + 7 = 15 for x, we'll need to isolate the absolute value expression and then solve for x.

Here's the step-by-step process:

Step 1: Subtract 7 from both sides of the equation:

|x - 5| = 15 - 7

|x - 5| = 8

Step 2: Break the equation into two cases, one with the positive value inside the absolute value and one with the negative value inside the absolute value.

Case 1: x - 5 is positive:

For this case, the equation |x - 5| = 8 becomes:

x - 5 = 8

Now, solve for x:

x = 8 + 5

x = 13

Case 2: x - 5 is negative:

For this case, the equation |x - 5| = 8 becomes:

-(x - 5) = 8

Simplify and solve for x:

-x + 5 = 8

-x = 8 - 5

-x = 3

Multiply both sides by -1 to isolate x:

x = -3

So, the solutions to the equation are x = 13 and x = -3.

Find the equation of a line that passes through the points (-4, -2) and (6, 3).

Answers

Answer:

[tex]y=\frac{1}{2} x[/tex]

Step-by-step explanation:

The equation of a line through two points can usually (except when the line is a vertical line) be written in slope intercept form,  [tex]y=mx+b[/tex] , where "m" is the slope of the line, and "b" is the y-intercept of the line.

General outlineFind the slopeFind the y-intercept
Step 1.  Find the slope

To find "m", use the formula for slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{(3)-(-2)}{(6)-(-4)}[/tex]

[tex]m=\dfrac{3+2}{6+4}[/tex]

[tex]m=\dfrac{5}{10}[/tex]

[tex]m=\dfrac{1}{2}[/tex]

So, the slope is 1/2 and we know that the equation for the line that passes through these two points should look like: [tex]y=\frac{1}{2} x+b[/tex]

Step 2.  Find the y-intercept

To find "b", substitute one of the known points, and solve for "b":

[tex]y=\frac{1}{2} x+b[/tex]

[tex](3)=\frac{1}{2} (6)+b[/tex]

[tex]3=3+b[/tex]

Subtracting 3 from both sides to isolate the "b"...

[tex](3)-3=(3+b)-3[/tex]

[tex]0=b[/tex]

So, the y-intercept is 0.  Substituting into our line equation, [tex]y=\frac{1}{2} x+(0)[/tex] which simplifies to [tex]y=\frac{1}{2} x[/tex]

The population of a town is growing exponentially and can be modeled by the

measured in years 1950.

C. According to this model approximately what is the population in 1960?

Answers

The population of the town in 1960 is 48.80 thousands

How to determine the population in 1950?

The equation of the model is given as:

f(t) = 42e^(0.015t)

1960 is 10 years after 1950.

This means that:

t = 10

Substitute t = 10 in f(t) = 42e^(0.015t)

f(10) = 42e^(0.015 * 10)

Evaluate

f(10) = 48.80

Hence, the population of the town in 1960 is 48.80 thousands

Multiplication is the process of multiplying. Jay lost 30 pounds in a period of 6 months.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

A.) The newly recorded temperature in January will be six times the temperature in February, therefore, we can write,

January = 6 × February = 6×(-3°F) = -18°F

Hence, the newly recorded temperature in January will be equal to -18°F.

B.) Change in water level on each day of the drought was equal to -4 inches, while the drought lasted for 1 week(7days), Thus, the net change in water level can be written as,

net change = 7 × -4 = -28inches

Hence, the net change in the water level during the drought was equal to -28 inches.

C.) Jay went on a diet for six months and lost 5 pounds each month, therefore, the net change in the weight will be equal to,

Net Change = 6 × 5 = 30 pounds

Solve for h.
6h= 7h + 5
H= ?

Answers

Answer:

h = -5

Step-by-step explanation:

1) Subtract 7th from both sides

6h = 7h + 5

6h - 7h= 7h + 5 - 7h

2) Simplify

- Combine like terms

6h - 7h = 7h + 5 - 7h

-h = 7h + 5 - 7h

- Combine like terms

-h = 7h + 5 - 7h

-h = 5

3) Divide both sides by the same factor

-h = 5

-h/-1 = 5/-1

4) Simplify

Cancel terms that are in both the numerator and denominator

h/-1 = 5/-1

h = 5/-1

Divide the numbers

h = 5/-1

h = -5

I used equation A to reduce to a usable substitute by dividing all by 3

And then isolating “h”.

Now substitute the value of “h” into equation B and solve for “p”

P=$1.50

To check your work, substitute p ($1.50) into equation B and solve for “h”

h=$4.00

Now substitute the p and h values into either equation A or B and solve, they equal the numbers given

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² - 8x + 8y + 23 = 0

volume = length × width × height

volume = 5 in. × 4 in. × 10 in.

Now lets simplify this fraction :

Divide top and bottom by 2 until you can't :

320/2000 = 160/1000

160/1000 = 80/500

80/500 = 40/250

40/250 = 20/125

Now we divide top and bottom by 5 as 2 is not a factor of 125 :

20/125 = 4/25
