I believe let me know if it wrong
The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.
Answer:
Since the graph looks like this, I would say solid line
X = Juan's age
y = Eliza's age
Some key words/phrases we can use to help us make the equation are:
-is (whatever comes after this word usually equals the end result, or what it equals)
-two years younger
-than
-half her brother's age
.
just break it down :)
x/2 (half her brother's age) - 2 (two years younger) = y (Eliza is...)
| basically,
v
x/2 - 2 = y
So if Juan is 6, then we need to plug in 6 for x.
6/2 - 2 = y
3 - 2 = y
1 = y
ANSWER: Eliza is one year old.
Answer:
x ≤ -11.25 or x > -8.75
Step-by-step explanation:
The graph here shows a disjunction compound inequality, in which either of the statements is true. That is for the compound inequality to be true, either one or the other statement is true. The word "OR" is used in stating this inequality.
On the graph, the directed line to our left has a full circle which starts at -11.25.
This means x ≤ -11.25.
The other directed line to our right has an empty circle, and starts at -8.75.
This means x > -8.75.
✅The compound inequality representing the graph will be written as:
x ≤ -11.25 or x > -8.75
