Answer:
The answer is A. {(5, 0), (-8, -5)}
Step-by-step explanation:
It's not B. because Since
x
=
−
8
produces
y
=
−
5
and
y
=
5
, the relation
(
5
,
0
)
,
(
−
8
,
−
5
)
,
(
−
8
,
5
)
,
(
−
5
,
−
8
)
is not a function.
The relation is not a function.
It's not C. because Since there is one value of
y
for every value of
x
in
(
5
,
0
)
,
(
0
,
5
)
,
(
−
5
,
−
5
)
It's not D. because Since
x
=
5
produces
y
=
0
and
y
=
−
5
, the relation
(
5
,
0
)
,
(
0
,
−
8
)
,
(
5
,
−
5
)
is not a function.
The relation is not a function.
Answer:
Add 81/4 to both sides.
Step-by-step explanation:
x^2 − 9x − 8 = 0
x^2 - 9x = 8
Take the coefficient of the x term: -9
Divide by 2: -9/2
Square it: 81/4
Add 81/4 to both sides.
From question,
lacy learned 34 recipes in 17 weeks,
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in
= 40*2
=80 recipes.

Answer:
7/12
Step-by-step explanation:
7/9 times 6/8 (which is simplified to 3/4) comes out simplified to 7/12. You would do this because you have 7 blue marbles and 9 total marbles at first, then you take one of each away. You want to find the probability, so you multiply both fractions
