Jason is 5 years older than bill,and bill is twice as old as sharon.how old is jason ?whic expression represent the best way to solve the following problem? A.2x+5. Or b.x2+5 or x+y+5 d.x2+y2+5 the question can b.becaused they said is not good!

Answers

Answer 1

Answer:

It is A. 2x+5

Bill is twice as old as Sharon, making it 2x.

Jason is 5 years older than Bill, making it 2x+5

(It can also be B. because 2x+5 and x2+5 are the same thing)

Draw quick pictures and write to explain how to break apart addends to find the sum of 324 + 231

Answers

Answer: The explanation of the given addition is mentioned below.

Step-by-step explanation:

Since Here we have numbers 324 and 231.

So if we want to add these two numbers then at first we should add 4 and 1, That is 4+1= 5, which is the once place digit of our answer.

Now we should add 2 and 3 , that is , 2+3 =5 which is the tense place digit of our answer.

Finally we should add 3 and 2 the result is 3+2= 5 , which is the hundreds place digit of our answer.

Thus the complete result is 555.

If set D is not the empty set but is a subset of set E, then which of the following is true? D ∩ E = D
D ∩ E = E
D ∩ E = Ø

Answers

Concept:
If every element of a set D is an element of set E, then D is the subset of E.
e.g
D={1,2,3}, E={1,2,3,4}
As all the elements of D are in E, so D is the subset of E.
Now the intersection of two sets D and E is the set of all elements which belong to both D and E.
As, in our example the set D={1,2,3} is the intersection of set D and set E.

From the above discussion, it is proved that If set D is not the empty set but is a subset of set E then
D ∩ E = D is the true answer.

Write the given expression in terms of x and y only tan(sin−1 x + cos−1 y)

Answers

Answer:

$\tan \left ( \sin ^(-1)x+ \cos ^(-1)y\right )=(xy+√(\left ( 1-x^2 \right )\left ( 1-y^2 \right )))/(y√(1-x^2)-x√(1-y^2))$

Step-by-step explanation:

We need to express $\tan \left ( \sin ^(-1)x+ \cos ^(-1)y\right )$ in terms of x and y .

Let $\sin ^(-1)x=\theta \,,\,\cos ^(-1)y=\phi$ , we get

$x=\sin \theta \,,\,y=\cos \phi$

Formulae Used:

$\sin ^2\theta +\cos ^2\theta =1\n\sin ^2 \phi +\cos ^2 \phi =1$

$\cos \theta =√(1-\sin^2 \theta)=√(1-x^2)\n\sin \phi=√(1-\cos ^2 \phi)=√(1-y^2)$

$\tan \theta =(\sin \theta )/(\cos\theta )=(x)/(√(1-x^2))\n\tan \phi =(\sin \phi)/(\cos\phi)=(√(1-y^2))/(y)$

We know that $\tan \left ( \theta +\phi\right )=(\tan \theta +\tan \phi )/(1-\tan \theta \,\tan \phi )$

$\tan \left ( \sin ^(-1)x+ \cos ^(-1)y\right )=((x)/(√(1-x^2))+(√(1-y^2))/(y))/(1-(x√(1-y^2))/(y√(-x^2)))\n\therefore \tan \left ( \sin ^(-1)x+ \cos ^(-1)y\right )=(xy+√(\left ( 1-x^2 \right )\left ( 1-y^2 \right )))/(y√(1-x^2)-x√(1-y^2))$

What is the graph of the system y= -2x + 3 and 2x + 4y= -8

Answers

y = -2x + 3
2x + 4y = -8

y = -2x + 3
y + 2x = 3

2x + 4y = -8

Subtract those equations
3y = -11
y = -11/3

y = -2x +3
-11/3 = -2x + 3
2x = 3 + 11/3
x = 3/2 + 11/6
x = 20/6
x = 10/3

therefore above lines will intersect in this ( 10/3 , -11/3 ) coordinates

Answers

Answer:

-18

Step-by-step explanation:

-4(-2)+(-12)÷(+3)+-20+(+4)+(-6). [B.E.D.M.A.Srule](Firstbracket)

= 8 - 12 ÷ 3 - 20 + 4 - 6. (Thendivision)

= 8 - 4 - 20 + 4 - 6. (Thenafteraddition)

= 8 + 4 - 4 - 20 - 6

= 12 - 30. (Atlastsubtraction)

= -18 (Ans)

Answer:

-18

Step-by-step explanation:

$-4(-2)+((-12))/(+3)-20+(+4)+(-6)=8-(12)/(3)-20+4-6=8-4-20+4-6=-18$
