Answer:

Step-by-step explanation:
Given the expression

According to the order of operation with respect to PEMDAS
so
Thus, the expression becomes

There are no like terms involved in the expression.
The expression is very much simplified.
Thus:

its X < 1 or x > 3
where every the point goes is where the graph goes is what I do
Answer:
The actual distance between the two houses is:
3.2 km
Step-by-step explanation:
Proportions:
1cm ⇔ 100000 cm
3.2 cm ⇔ W cm
W = 3.2*100000/1
W = 320000 cm
1 km = 100000 cm
320000cm = 320000/100000 = 3.2km
For

and

, it's helpful to remember the half-angle identities:


So


For

, the Pythagorean identity suffices:

which means

since

.
A.) it opens up because it is positive. B. The vertex is a minimum, because it opens up C/ The axis of symmetry is X=-1, the Vertex is (-1,-2). The Y interecept is y= -1
