Please help me to find this answer

Let the numbers are x and y

According to the question

⇒x+y=1000.....eq1⇒x 2 −y 2

=256000∵x 2 −y 2

=(x+y)(x−y)

⇒1000∗(x−y)=256000

⇒x−y=256.....eq2

Adding eq1 and eq2

⇒2x=1256⇒x=628

Put the value of x in eq1

⇒628+y=1000⇒y=372

The numbers are 628 and 372

Answer:

[tex]x= 80^o[/tex]

Step-by-step explanation:

Given

[tex]\angle Z = 36^o[/tex]

[tex]\angle WYZ = 100^o[/tex]

Required

Find x

[tex]\angle WYZ[/tex] and x are on a straight line.

So:

[tex]\angle WYZ + x= 180^o[/tex]

Make x the subject

[tex]x= 180^o -\angle WYZ[/tex]

Substitute known value

[tex]x= 180^o -100^o[/tex]

[tex]x= 80^o[/tex]

Answer:

80 is correct

Step-by-step explanation:

Answer:

The third choice is the correct one.

Step-by-step explanation:

The absolute value of six means that it's the distance from 0 to six, and that distance will be positive regardless of the number being negative or not.

Answer: The third answer is correct

Step-by-step explanation:

Since |6| is the absolute value of positive six, the value of an absolute value of any number is always positive.

Step-by-step explanation:

Answer:

1217

Step-by-step explanation:

Given

[tex]Subjects = 2353[/tex]

[tex]Improvement = 1136[/tex]

Required

The number that didn't improve --- missing from the question.

Let the unimproved be represented as x.

So, we have:

[tex]x + Improvement = Subjects[/tex]

Substitute known values

[tex]x + 1136 = 2353[/tex]

Solve for x

[tex]x =- 1136 + 2353[/tex]

[tex]x =1217[/tex]

Answer:

Step-by-step explanation:

Replace (x, y) with (1, 1) and verify if the equations are correct.

You would ignore the x and y in the equations. Testing one of each pair.

It is obvious that only b. is correct.

Answer:

[tex]\angle C \cong \angle F[/tex]

Step-by-step explanation:

Given

[tex]AB \cong DE[/tex]

See attachment

Required

What proves [tex]\triangle ABC \cong \triangle DE F[/tex] by AAS

We have:

[tex]\angle A \cong \angle D[/tex] --- Angle

[tex]AB \cong DE[/tex] --- Side

We need to prove that one more angle are congruent

[tex]\angle B \cong \angle E[/tex]

The above angles are congruent; however, it will prove [tex]\triangle ABC \cong \triangle DE F[/tex] by ASA

So, we make use of:

[tex]\angle C \cong \angle F[/tex] because it completes the proof by AAS

Answer:

3, 11, 35.

Step-by-step explanation:

The first 3 terms of the sequence can de written as:

n, 3n + 2, 3(3n + 2) + 2

So when n = 3 the first 3 terms are

3, 3(3) + 2,  3(3(3) + 2)) + 2

= 3 , 9 + 2, 33 + 2

= 3, 11, 35.

Answer:

4x+2y

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

The angles are vertical angles and vertical angles are equal

150 = 4x+50

Subtract 50 from each side

150-50 = 4x+50-50

100 = 4x

Divide by 4

100/4 = 4x/4

25 = x

Answer:

a). Not a proposition

b). Proposition

Step-by-step explanation:

A statement or a proposition is defined as a statement which is known to be true or it is known to be false. But a proposition cannot be both false and true.

If the sentence is not known to be true or false then the sentence is not considered to be a proposition or a statement.

a). All dogs go to heaven.

We do not have any idea that whether all dogs go to heaven or not. Since we do not know whether the sentence is true or false, hence it is not a proposition or a statement.

b). Do you have a Nintendo Switch or a PlayStation 5

In this sentence, I can have either a Nintendo Switch or a PlayStation 5. So the sentence can be either true or false. Since we know the sentence is can be either true or can be false, thus it is a proposition.

Answer:

The answer is −3y^2−y.

Steps:

Distribute the Negative Sign:

=−2y2+−1(y2+y)

=−2y2+−1y2+−1y

=−2y2+−y2+−y

Combine Like Terms:

=−2y2+−y2+−y

=(−2y2+−y2)+(−y)

=−3y2+−y

Answer:

-3y^2 - y

Step-by-step explanation:

-2y^2 - (y^2 + y)

Find the opposite of y^2 + y, so distribute the negative sign to the values inside the parentheses to get:

−2y^2 −y^2 − y

Then combine like terms to get:

-3y^2 - y

Answer:

option c is the answer for your question

Answer: Bill, 1

Step-by-step explanation:

Given

Bill and will run a 400 yard race.

Bill win by 20 yard

Suppose the speed of Bill and Will are [tex]\mathbf{v_b}, \mathbf{v_w}[/tex]

time taken for them is same for the first time

[tex]\Rightarrow t_b=t_w\\\\\Rightarrow \dfrac{400}{v_b}=\dfrac{400-20}{v_w}\\\\\Rightarrow \dfrac{v_b}{v_w}=\dfrac{400}{380}\ or\ \dfrac{20}{19}\\[/tex]

Now Bill starts 20 yards behind the starting line

Ratio of their time to cover the distances is

[tex]\Rightarrow \dfrac{t_b}{t_w}=\dfrac{\dfrac{420}{v_b}}{\dfrac{400}{v_w}}\\\\\Rightarrow \dfrac{t_b}{t_w}=\dfrac{420}{400}\times \dfrac{v_w}{v_b}\\\\\Rightarrow \dfrac{t_b}{t_w}=\dfrac{21}{20}\times \dfrac{19}{20}\\\\\Rightarrow \dfrac{t_b}{t_w}=\dfrac{399}{400}[/tex]

The obtained ratio is less than 1. Thus, the time taken by Bill is less than Will.

For the same time Bill wins

[tex]\therefore \dfrac{v_b\times t}{v_w\times t}=\dfrac{420}{x}\\\\\Rightarrow x=19\times 21\\\Rightarrow x=399\ m[/tex]

Thus, Will has covered only 399 yards.

This time Bill wins by 1 yards.

Step-by-step explanation:

The domain is the list of the first numbers of the ordered pairs. If there are any duplicates, the relation is not a function. Here, the first numbers are {6, -9, 1}. Most folks find it convenient to list them in numerical order:

  {-9, 1, 6} . . . . domain of G

__

The range is the list of second numbers of the ordered pairs. Only the distinct values are reported. Here, the second numbers are {0, -3, -3}.
