What is the equation of the vertical line through (2,3)?

Answer»

Answer:

x = 2

Step-by-step explanation:

If you plot this point and draw a vertical line, you will see that the x-coordinate for any point on this line NEVER CHANGES. The x-coordinate will always be 2 for any point on this line.

Thus we can REPRESENT this line with x = 2.

Answer»

Answer:

Subtract 2/5 from 4/7

Solution:

The additive INVERSE of 2/5 is -2/5

THEREFORE, 4/7 - 2/5 = 4/7 + (-2/5)

⇒ 4/7 - 2/5 = 4 × 5/7 × 5 + (-2) × 7/5 × 7

= 20/35 + -14/35

= 20 + (-14)/35

= 6/35

Therefore, 4/7 - 2/5 = 6/35

2. Subtract -6/7 from -5/8.

Solution:

The additive inverse of -6/7 is 6/7

Therefore, -5/8 - (-6/7) = -5/8 + 6/7, [Since, -(-6/7) = 6/7)]

⇒ -5/8 - (-6/7) = -5 × 7/8 × 7 + 6 × 8/7 × 8

⇒ -5/8 - (-6/7) = -35/56 + 48/56

⇒ -5/8 - (-6/7) = -35 + 48/56

⇒ -5/8 - (-6/7) = 13/56

Therefore, -5/8 - (-6/7) = 13/56

3. Subtract -4/9 from 2/5

Solution:

The additive inverse of -4/9 is 4/9.

Therefore, 2/5 - (-4/9) = 2/5 + 4/9, [Since, -(-4/9) = 4/9)]

⇒ 2/5 - (-4/9) = 2 × 9/5 × 9 + 4 × 5/9 × 5

⇒ 2/5 - (-4/9) = 18/45 + 20/45

⇒ 2/5 - (-4/9) = 18 + 20/45

Therefore, 2/5 - (-4/9) = 38/45

4. The sum of two RATIONAL numbers is -3/5. If one of the NUMBER is -9/20, find the other.

Solution:

Sum other number = -3/5, One number = -9/20

Therefore, the other number = Sum of the two rational numbers - One of the given rational number.

= -3/5 - (-9/20)

= -3/5 + 9/20, [Since - (-9/20) = 9/20]

= (-3) × 4 + 9 × 1/20

= -12 + 9/20

= -3/20

Therefore, the required rational number is -3/20.

5. Which rational number should be added to -7/11 so as to get 4/7?

Solution:

Su of the given number and the required rational number = 4/7.

Given rational number = -7/11.

Therefore, the required number = Sum - Given number

= 4/7 + 7/11

= 4 × 11/7 ×11 + 7 × 7/11 × 7

= 44/77 + 49/77

= 44 + 49/77

= 93/77

Thus, the rational number 93/77 should be added to -7/11 so as to get 4/7.

6. What should be SUBTRACTED from -4/5 so as to get 6/15?

Solution:

Difference of the given rational number and the required rational number = 6/15.

Given rational number = -4/5.

Therefore the required rational number = -4/5 - 6/15

= -4/5 + -6/15

= (-4) × 3/5 × 3 + -6/15

= -12/15 + -6/15

= (-12) + (-6)/15

= -18/15

= -6/5

Thus, the rational number -6/5 subtracted from -4/5 so as to get 6/15.

If HCF of 408 and 1032 is expressible in the form of 1032 m - 480 x 5, find m. ​

Answer»

Answer:

plz mark as brainliest

Step-by-step explanation:

First FIND out the hcf

1032=408×2 + 216

408=216×1 + 192

216=192×1 + 24

192=24×8 + 0

so, now SINCE the REMAINDER has COME zero

so the hcf will be 24

now if we put hcf=1032-408×5

1032m-408×5=24

1032m-2040=24

1032m=24+2040⇒2064

m=2064÷1032⇒2

2 is the VALUE of m.

Worker A completes a task in 8 days and worker B completes the same task in 10 days. If both A and B work together, in how many days they will complete the task?

Answer»

Answer:

both will complete the WHOLE TASK in 40/9

Step-by-step explanation:

WORKER A completes the task in 8 days. So in one day he will complete 1/8 part of the task.

So, A's one day work =1/8

Similarly, B's one day work =1/10

∴ (A+B)'s one day work =1/9 + 1/10 = 9/40

9/40 of the task is completed in one day so both will complete the whole task in 40/9

A man borrows Rs 6000 at 5% CI. If he repays 1200 at the end of each yr find the amount outstanding at the begining at the third yr. previous answer is wrong.​

Answer»

Answers

Given Principle amount = Rs . 6000

And

Rate of INTEREST = R = 5% compounded annually

So,

Interest after 1 year = 6000 × 5 × 1100 = 60× 5 = Rs . 300

Total money owed after 1 year = 6000 + 300 = 6300

And

Rs. 1200 paid , So

Total money starting of second year = 6300 - 1200 = Rs.5100

And

Interest after 2 year = 5100 × 5 × 1100 = 51× 5 = Rs . 255

money owned after 2 year = 5100 + 255 = 5355

And

Rs. 1200 paid , So

Total money outstanding starting of Third year = 5355 - 1200 = Rs.4155 ( Ans )
