Answer:
the relation is NOT a function
domain: {
1,-2,1}
range: {
-2, 0, 2, 3}
Step-by-step explanation:
Answer: 24 and 76
Step-by-step explanation:
{
d
+
q
=
100
10
d
+
25
q
=
2140
From the first equation, we have
d
=
100
−
q
Substituting that into the second equation, we have
10
(
100
−
q
)
+
25
q
=
2140
⇒
1000
−
10
q
+
25
q
=
2140
⇒
15
q
=
1140
⇒
q
=
1140
15
=
76
Knowing that
q
=
76
we can substitute that value into the first equation to obtain
d
+
76
=
100
∴
d
=
24
Thus, Sue has
24
dimes and
76
quarters.
That'd be 3000 + 30 + 0.03 + 0.003, or 3030.033
hope this helped :)

plzz tell me if I was wrong
For every ticket purchased, the cost will increase by $15.00 because x indicates that $15 is the unit rate for each ticket.
Okay so triangle DEA = 71 degrees
And angle DEB = 90 degrees (right angle)
90 - 71 = 19 degrees
Angle EBA = 90 degrees (right angle)
That leaves the 90 degrees + 19 degrees = 109 degrees
There’s 180 degrees in a triangle so
180 - 109 = 71 degrees
