Which equation has the same solution as x^2+10x+9 = 4

1 answer:

8 0

To factor you must play with factors which multiply to
9

(
1
×
9
,

3
×
3
,

9
×
1
)
(
x
−
9
)
(
x
−
1
)
=
0
Now, solve each factor for
0
:
x
−
9
=
0
x
−
9
+
9
=
0
+
9
x
−
0
=
9
x
=
9
and
x
−
1
=
0
x
−
1
+
1
=
0
+
1
x
−
0
=
1
x
=
1

Which equation represents a linear function?

quester [9]

Answer:

Step-by-step explanation:

y = 9 - X is a linear function; x is to the first power.

y = x2 + 1 does NOT represent a linear function; it's a quadratic function.

y=x² + 5 does NOT represent a linear function; it's a quadratic function.

y = [xl - 9 does NOT represent a linear function; it's an absolute value function. This function has two halves, each of which is a linear function.

But the best answer here is that y = 9 - X is a linear function; x is to the first power.
