Does (x, y) satisfy the inequality?
Full solution
Q.
Does
(

)
(9, 4)
(
9
,
4
)
make the inequality
y
≥
6
x
+
7
y \geq 6x + 7
y
≥
6
x
+
7
true?
\newline
Choices:
\newline
(A) yes
\newline
(B) no
Substitute values into inequality:
Substitute the values
9
,
4
9, 4
9
,
4
into the inequality
y
≥
6
x
+
7
y \geq 6x + 7
y
≥
6
x
+
7
. The substituted inequality is
4
≥
6
(
9
)
+
7
4 \geq 6(9) + 7
4
≥
6
(
9
)
+
7
.
Calculate right side:
Calculate the right side of the inequality
6
(
9
)
+
7
6(9) + 7
6
(
9
)
+
7
. Simplify this to get
54
+
7
54 + 7
54
+
7
.
Add values:
Add
54
54
54
and
7

7
to get
61

61
. The inequality now reads
4
≥
61
4 \geq 61
4
≥
61
.
Check inequality:
Determine if the point
(
9
,
4
)
(9, 4)
(
9
,
4
)
makes the inequality
4
≥
61
4 \geq 61
4
≥
61
true. Since
4
4
4
is not greater than or equal to
61
61
61
, the statement is false.
