Yes! That graph matches the equation
x
=
−
7
or
x
=
−
8
Explanation:
Find a pair of factors of
56
with sum
15
.
The pair
7
,
8
works in that
7
⋅
8
=
56
and
7
+
8
=
15
Hence:
0
=
x
2
+
15
x
+
56
=
(
x
+
7
)
(
x
+
8
)
So:
x
=
−
7
or
x
=
−
8

Step-by-step explanation:
Answer:
<u>D. Taylor correctly found the distance between –4 and 45, but this number represents the total distance the team moved in both directions, not the team’s total gain.</u>
Step-by-step explanation:
The team only ended up gaining the 45 yards on the second play and had gained -4 on the first play. 45-4≠49, but the total distance between -4 and 45 is 49.
