The distance between the two points is 5 units

Explanation:

Given that the two points are located at (-9,-8) and (-6,-4)

We need to determine the distance between these two points using Pythagorean theorem.

The distance between the two points can be determined using the formula,

c=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substituting the coordinates (-9,-8) and (-6,-4) in the above formula, we get,

c=\sqrt{(-6+9)^2+(-4+8)^2}

Simplifying, we get,

c=\sqrt{(3)^2+(4)^2}

Squaring the terms, we get,

c=\sqrt{9+16}

Adding the terms, we have,

c=\sqrt{25}

Simplifying, we get,

c=5

Thus, the distance between the two points is 5 units.

Linear equation: -1
Anika [276]

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality

Is 9 a solution to the equation 21=3p-5? Show work
Dmitry_Shevchenko [17]

Answer:

No

Step-by-step explanation:

21 = 3p - 5

<u>Step 1</u> : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

<u>Step 2</u> : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.

Help I have to turn this in. In a couple hours

28. Surface Area

This is some sort of house-like model so for every face we see there's a congruent one that's hidden.  We'll just double the area we can see.

Area = 2 × ( [14×9 rectangle] + 2[15×9 rectangle]+[triangle base 14, height 6] )

Let's separate the area into the area of the front and the sides; the front will help us for problem 29.

Front =  [14×9 rectangle] + [triangle base 14, height 6]

          = 14×9 + (1/2)(14)(6) = 14(9 + 3) = 14×12 = 168 sq ft

OneSide =  2[15×9 rectangle] = 30×9 = 270 sq ft

Surface Area = 2(168 + 270) = 876 sq ft

Answer: D) 876 sq ft

29.  Volume of an extruded shape is area of the base, here the front, times the height, here 15 feet.  

Volume = 168 * 15 = 2520 cubic ft

Answer: D) 2520 cubic ft

The sum of two numbers is 10. twice the first number is 4 more than twice the second. what are the two numbers?
Ludmilka [50]
X+ y = 10
2x = 2y+4

2x/2 = 2/2y+4/2
x = y + 2

x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4

x + y =10
x + 4 =10
x +4-4 =10-4
x = 6

Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
