What is the interval notation for the graph shown below?
Scrat [10]
<h3>Answer: Bottom left corner (southwest corner)</h3>

(4, \infty)

The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"

The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity

The interval from 4 to infinity is written as (4, \infty) which is like saying 4 < x < \infty

Pls help meee!!
maksim [4K]

Answer:

7*6-x

or

42-x

Step-by-step explanation:

decrease means subtraction,

product means multiplication

let x be the number you are decreasing by.

I am not really sure how to explain this, but here I go.

you take away x from the number that equals 6*7.

6*7 is 42 and you take away x from that, you get 42-x

or if you want to leave it unsimplified,

6*7-x

Please answer this im so confused
-Dominant- [34]

Step-by-step explanation:

  1. Since,in question 21 the trspezium is an isoseles tapizium
  2. therefore,9x-17=4x+28
  3. 5x=45
  4. x=9
  5. therefore q=9x-17
  6. =9*9-17
  7. =81-17
  8. q=64
  9. therefore 2t=360-128(since its isoseles triangle therefore adjacent base angles are equal)
  10. 2t=23
  11. t=116
  • In question 28
  1. 2(K+M)=360
  2. 2(3x+16 + 11x-18)=360
  3. 2(14x-2)=360
  4. 28x-4=360
  5. 28x=364
  6. x=13
  7. J=K
  8. Isoleses angles are equal
  9. 3x+16=J
  10. 39+16=J
  11. J=55
  • In question 29
  1. Bd=Ec (Congeruent sides of congurent trisnle are equal,BED~=CDE)
  2. 8x-27=2x+33
  3. 6x=60
  4. x=10
  5. Therefore,Bd=8x-27
  6. Bd=80-27
  7. Bd=53
