Answer:

slop = 2/3

Step-by-step explanation:

slope = rise/run

Start at the lower left point (-2, -1).

We need to go to the upper right point (4, 3) by going only vertically (rise) and horizontally (run).

First we go up 4. The rise is 4.

Then we go right 6. The run is 6.

slope = m = rise/run = 4/6 = 2/3

slope = 2/3

Answer:

0

Step-by-step explanation:

-6(2(1/3)+3(2/3(3))=

Starting with pedmas (parenthesis, exponents, division, mulitplication, addition, subtraction).

We look at 2*1/3 and 2/3*3

[tex]2*\frac{1}{3}=\frac{2}{3}[/tex] and [tex]\frac{2}{3}*3=2[/tex]

To find the greatest common factor, line both numbers up and continue adding that specific number until you find two factors that correlate with both numbers.

With that being said, let's begin.

8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88

Simply add 8.

11: 11, 22, 33, 44, 55, 66, 77, 88

Simply add 11.

The greatest common factor of 8 and 11 is 88.

Answer:

y = x + 8

Step-by-step explanation:

Let's build the equation:

There are 8 entries to start

y = 8

Adding 1 entry every day

y = x + 8

Step-by-step explanation:

the essential thing to remember here (and please, burn this into your brain for life) : the sum of all angles in a triangle is always (really always) 180 degrees.

therefore, in 12 and 13 we only need to add all 3 angles, and their sum must be 180.

from there we get really all 4 answers.

the next thing to consider is when a triangle had two equal angles, then it is an isoceles triangle (the 2 sides leading away from these 2 angles are equally long). that gives us the answers for 14 and 15.

12.

3x + 18 + 7x - 58 + 2x - 8 = 180

12x - 48 = 180

12x = 228

x = 19

angle A = 3x+18 = 3×19 + 18 = 57+18 = 75 degrees

angle B = 7x-58 = 7×19 - 58 = 133-58 = 75 degrees

angle C = 2x-8 = 2×19 - 8 = 38 - 8 = 30 degrees

13.

8x - 17 + 19x + 4 + 5x + 1 = 180

32x - 12 = 180

32x = 192

x = 6

angle Q = 8x-17 = 8×6 - 17 = 48-17 = 31 degrees

angle R = 19x+4 = 19×6 + 4 = 114+4 = 118 degrees

angle S = 5x+1 = 5×6 + 1 = 30+1 = 31 degrees

14.

KL = 9x - 14

LM = 7x - 37

KM = 3x + 23

angle K = angle L

so, the sides LM and KM must be equally long. that gives us

7x - 37 = 3x + 23

4x = 60

x = 15

KL = 9x-14 = 9×15 - 14 = 135-14 = 121

LM = 7x-37 = 7×15 - 37 = 105-37 = 68

KM = 3x+23 = 3×15 + 23 = 45+23 = 68

15.

XY = 13x - 21

YZ = 8x - 6

XZ = x + 4

angle X = angle Z

so, the sides XY and ZY (or YZ) must be equally long. that gives us

13x - 21 = 8x - 6

5x = 15

x = 3

XY = 13x-21 = 13×3 - 21 = 39-21 = 18

YZ = 8x-6 = 8×3 - 6 = 24-6 = 18

XZ = x + 4 = 3+4 = 7

Answer:

Should be -69 1/3

Step-by-step explanation:

Let X equal the decimal number

Equation 1:

X=69.3333333333¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

With 10 digits in the repeating decimal group,

create a second equation by multiplying

both sides by 1010 = 10000000000

Equation 2:

10000000000X=693333333333.3333333333¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

Subtract equation (1) from equation (2)

10000000000XX9999999999X===693333333333.3333333333...69.3333333333...693333333264

We get

9999999999X=693333333264

Solve for X

X=6933333332649999999999

Find the Greatest Common Factor (GCF) of 693333333264 and 9999999999, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 3333333333,

693333333264÷33333333339999999999÷3333333333=2083

Simplify the improper fraction,

=6913

In conclusion,

−69.3333333333¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯=−6913

Answer:

a = 25°

Step-by-step explanation:

Subtraction is a mathematical operation that reflects the removal of things from a collection. The least possible height of the mont blanc is 4800 meters.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given the height of mont blanc is 4810 m correct to the nearest 10 meters. Therefore, the least possible height of the mont blanc can be written as,

Least height = 4810m - 10m = 4,800 meters

Hence, the least possible height of the mont blanc is 4800 meters.

If I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

The term PEMDAS describes the sequence in which arithmetic operations must be carried out in an equation.

It is given that the length of the toy model car is 15 inches and the actual car is 20 feet

As we know 1 foot consists of 12 inches as a result  20 feet has 240 inches.

The scale distance between the toy model and the actual car is the difference between the actual length and the model length.

Scale distance = 240 inches - 15 inches

Scale distance =225 inches

Thus, if I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

It will take 2 seconds a jet to accelerate from 200 m/s to 300 m/s with a constant acceleration of 50 m/s.

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

Given:

A constant acceleration is of 50 meter per second.

A jet to accelerate from 200 m/s to 300 m/s.

Acceleration is 100 meters per 2 seconds.

That means,

it will take = (300 - 200)/ 50 m/s

                = 2 seconds.

Therefore, it will take 2 seconds.

Answer:

1.99c + 59 ≥ 75, where c ≥ 8.04

Step-by-step explanation:

Answer:

1. C,  2. A,  3. C,  4. B

Step-by-step explanation:

Parallel:  slopes are equal.  In problem 2, the slopes appear to be 2 ("rise over run") One line passes through points (2, 1) and (3, 3) -- y increases by 2 if x increases by 1.  The other line passes through points (0, 3) and (1, 5)  -- y increases by 2 if x increases by 1.  The lines have the same slope.

Perpendicular:  slopes are opposite reciprocals (they have opposite signs).  In problem 4, that happens:  2/3  and  -3/2.  That is not the relationship between slopes in problem 3.  1/3 and 3 are not opposite reciprocals.

Corrected!  #4 is B (perpendicular)
