Answer:
If 23-26, that is -3
Well, because 23 can't minus 26, that's why you have to rearrange so that you can find the correct answer by letting -26 + 23.
Answer:
do it
Step-by-step explanation:
can determine that 8 is more than -9 by looking which one is more further to the right, since I see 8 I assume it is 8 and that would be correct
Kelly's sister is x years old.
Kelly is 3 years younger than her sister, so Kelly is x - 3 years old.
The sum of their ages is x + x - 3 = 2x - 3.
The sum of their ages is 34, so
2x - 3 = 34
2x = 37
x = 18.5 Kelly's sister's age.
x - 3 = 18.5 - 3 = 15.5 Kelly's age.
Kelly's sister is 18.5 years old.
Kelly is 15.5 years old.
Answer:
{ x | -3 <= x < +1 }
Step-by-step explanation:
We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).
Thus the domain is { x | -3 <= x < +1 }
Answer:
f light is imagined as a flow of particles, the particles are called photons with each photon carrying a discrete packet of energy.
