It’s very very good jk it’s important because it helps with percentages
Answer:
where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is
.
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as ![(a,-a^2-2a+8)](https://tex.z-dn.net/?f=%28a%2C-a%5E2-2a%2B8%29)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
where −5 ≤ x ≤ 3.
Answer:
Percentage change=140%
Step-by-step explanation:
The expression for the percentage change is as follows;
C={(F-I)/I}×100
where;
F=final quantity
I=initial quantity
C=percentage change
In our case;
C=unknown
F=24 gallons
I=10 gallons
replacing;
percentage change={(24-10)/10}×100
percentage change=(14/10)×100
percentage change=140%
Answer:
Step-by-step explanation:
basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below
