15
Explanation:
If the zero is c, the factor is (x-c).
So for zeros of
−
3
,
−
1
3
,
5
, the factors are
(
x
+
3
)
(
x
+
1
3
)
(
x
−
5
)
Let's take a look at the factor
(
x
+
1
3
)
. Using the factor in this form will not result in integer coefficients because
1
3
is not an integer.
Move the
3
in front of the x and leave the
1
in place:
(
3
x
+
1
)
.
When set equal to zero and solved, both
(
x
+
1
3
)
=
0
and
(
3
x
+
1
)
=
0
result in
x
=
−
1
3
.
f
(
x
)
=
(
x
+
3
)
(
3
x
+
1
)
(
x
−
5
)
Multiply the first two factors.
f
(
x
)
=
(
3
x
2
+
10
x
+
3
)
(
x

)
Multiply/distribute again.

The answer is: [B]: x <span>> -10
__________________________
Explanation:
___________
Given the inequality:
___________
</span>→ <span>x + 2 > - 8 ;
____________
</span>→ Subtract<span> "2" from EACH side; to isolate "x" on one side; and solve, or simplify, for "x" ;
_______________________
</span>→ x + 2 − 2 > - 8 − 2 ; to get:
_______________________
→ x > -10 ; which is: 'Answer choice: [B]'.

perpendicular means negative reciprocal so it would be -1/3
Answer:
see below
Step-by-step explanation:
10 are blue, 30 are yellow, 20 are red, and 40 are green.
There are 100 marbles in the bag
The color that has the most marbles is green
P( green) = 40/100 = 40%
P( yellow) = 30/100 = 30%
P( red) = 20/100 = 20%
P( blue) = 10/100 = 10%
You will be more likely to pick a green marble
