Answer:
go to a called math and way but without the space or the and
Step-by-step explanation:
Well, you want to solve for a. You first add the 4 to both sides.
3a-4<5
3a<9
Then you want to get a by itself so you divide both sides by 3. Since the 3 is positive you don't have to worry about switching the sign. It stays this way <
After you divided both sides by 3 you get a<3
Answer:
Step-by-step explanation:
You can't ever let this go negative. At least not at the grade you are in.
It can be 0.
So the domain must start at x = 7
sqrt(5*7 - 35) = sqrt(0) = 0
x can have any value (including 7) between 7 and infinity. If you choose a number less than 7 (like 6) the square root will go negative and that's not to be done.
So the interval is
7 ≤ x < ∞
