Step-by-step explanation:

[tex] \frac{1}{x} - \frac{1}{x - 2} = 3[/tex]

× All by x(x-2) both sides of equation

(x-2)-x = 3x(x-2)

x-2-x = 3x² - 6x

-2 = 3x² - 6x

0 = 3x² - 6x +2

3x² - 6x + 2 = 0

and use the formula

[tex]x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

Find the midpoint between the two points (-2, 6) and (-4,-4).

answer ( ?,?) ​

Answers

Hey there! I'm happy to help!

To find the x value of the midpoint, add the x values and divide by 2.

-2+(-4)=-2-4=-6

-6/2=-3

For the y value, add the y values and divide by 2.

6+(-4)=6-4=2

2/2=1

So, our midpoint is (-3,1).

HELP PLS! What is the value of x? Enter your answer in the box. ___°

Answers

Answer:

127°

Step-by-step explanation:

I remember a teacher gave me a solution to solve these types of questions.

choose only one corner and draw lines from that Corner to the rest of the corners to form triangles.

for example, in this question, I choose 120°. 1 line to 125°, 1 to 133°, one to 112°. you can't draw any straight lines to the rest of the corners.

now you have 4 triangles. and the sum of the angles of each triangle, is 180°. so, the sum of the angles of this Irregular hexagon is 4×180=720°.

now:

112+133+120+100+128+x=720

593+x=720

x=720-593

x=127°

Find the midpoint of the segment with the following endpoints (-3,-9)(-7,-3)

Answers

Answer:

(-5,-6)

Step-by-step explanation:

Let(-3,-9)=(x1,y1)

(-7,-3)=(x2,y2)

Using midpoint formula,

Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)

=((-3+(-7))/2,(-9+(-3))/2))

=((-3-7)/2),(-9-3)/2))

=((-10/2),(-12/2))

=(-5,-6)

Thus midpoint(x,y)=(-5,-6)

The equation T = A3/2 is great if you know A and want to find T. Now, identify the correct inverse equation, which can be used to find A when you are given T. A = T2/3 A = T3/2 T = A2/3 T = A3/2

Answers

The inverse equation of the equation is: A =T2/3

The equation is given as:

T = A3/2

To calculate the inverse equation, we start by multiplying both sides of the equation by 2

T2 = A3

Next, we divide both sides of the equation by 3

A =T2/3

The equation cannot be further simplified

Hence, the inverse of the equation is: A =T2/3

Math problem a recipe for a dessert requires 3 4/5 cups of strawberries and 1.5 cuos of yogurt . How many cups of strawberries should be used if the recipe was tripled

Answers

Answer:

The number of cups of strawberries to be used is 11 2/5 cups

Step-by-step explanation:

Here, we want to know how many cups of strawberries to be used given that the recipe was tripled.

From the question, we are told that the recipe required 3 4/5 cups of strawberries.

Now, by tripling the recipe, it means we will be tripling the individual cups too.

So the number of cups of strawberries to be used will be ;

3 4/5 * 3

3 4/5 as improper fraction is 19/5

so we have 19/5 * 3 = 57/5 = 11 2/5

What type of sequence is the following numbers? 16, 32, 48, ... SOMEONE HELP ME

Answers

Answer:

the sequence would be an arithmetic sequence.


Explanation:

it is adding 16 to each value, 16 + 16 = 32,
32 + 16 = 48
hope this helps! :)

The given sequence of numbers, 16, 32, 48, forms an arithmetic sequence.

Given is a sequence of numbers 16, 32, 48.......... we need to check the type of the sequence.

To determine if a sequence is arithmetic, we can check if the difference between any two consecutive terms is the same.

Let's calculate the differences between the terms in the given sequence:

32 - 16 = 16

48 - 32 = 16

As we can see, the difference between each pair of consecutive terms is 16. This constant difference confirms that the sequence is arithmetic.

In an arithmetic sequence, each term can be obtained by adding the common difference to the previous term. In this case, we add 16 to each term to get the next term:

16 + 16 = 32

32 + 16 = 48

Therefore, the pattern of the given sequence is that each term is obtained by adding 16 to the previous term.

Hence the sequence is an arithmetic sequence.

Consider the triangle. Triangle A B C is shown. Side A B has a length of 15, side B C has a length of 8, side C A has a length of 12. The measures of the angles of the triangle are 32°, 53°, 95°. Based on the side lengths, what are the measures of each angle? mAngleA = 95°, mAngleB = 53°, mAngleC = 32° mAngleA = 32°, mAngleB = 53°, mAngleC = 95° mAngleA = 43°, mAngleB = 32°, mAngleC = 95° mAngleA = 53°, mAngleB = 95°, mAngleC = 32°

Answers

Answer:

B

Step-by-step explanation:

mAngleA = 32°, mAngleB = 53°, mAngleC = 95°

The order of sides is equal to the order of opposite angles, which helps us to find that m ∠A = 32°, m ∠B = 53°, and m ∠C = 95°.

Hence, the second option is the right choice.

What is the relation between the sides and the angles of a triangle?

In a triangle ABC, where a = BC, b = CA, and c = AB, and we are given that a > b > c, then we can see that ∠A > ∠B > ∠C, that is, the sides and the opposite angles follow the same order.

The largest side of the triangle is opposite the largest angle, while the shortest side of the triangle is opposite the shortest angle.

How to solve the question?

In the question, we are asked to consider a triangle ABC, where AB has a length of 15, BC has a length of 8, and CA has a length of 12.

The angles of this triangle are 32°, 53°, and 95°.

We are asked to find the measure of each angle based on the side lengths.

The side opposite  ∠A is BC = a.

The side opposite  ∠B is CA = b.

The side opposite  ∠C is AB = c.

We are given that, AB = 15, BC = 8, and CA = 12.

Thus we can write that AB > CA > BC or c > b > a.

Now, we know that opposite angles follow the same order.

Therefore, we can write that ∠C > ∠B < ∠A.

The 3 angles given to us are 32°, 53°, and 95°.

Thus, we can say that m ∠A = 32°, m ∠B = 53°, and m ∠C = 95°.

Hence, the second option is the right choice.

Answer: Associative Property

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

Explanation:

The given equation is in the form

a + (b+c) = (a+b) + c

where,

a = -2.2b = -3.7c = -1.4

The associative property of addition is what specifically is being applied. There's a multiplication version of this property as well. The associative property is the idea where we can move parenthesis around to group terms in different ways, and still get the same result regardless of what we did with the parenthesis.

------------

The associative property only works with addition and multiplication. Something like subtraction will be a different story

Eg: 1-(2-3) is different from (1-2)-3, so a-(b-c) is not the same as (a-b)-c
