Answer:
4
Step-by-step explanation:
Just plug in -9 to the equation
6(-9) + 9y = -18
-54 + 9y = -18 isolate 9y
54 - 54 + 9y = -18 + 54
9y = 36 isolate y
9y/9 = 36/9
y = 4
Answer:
Step-by-step explanation:
You must have made a mistake
the point-slope equation y – 8 = 1/2 (x – 4)?
If so，res is f(x)=1/2 x+6
Answer:
I can't see all the options but just go horizontally to the left 4 then vertically 3 up

Answer:
mean= 17.5
Q1= .5
Q3= 30.5
interquartile= 30
Step-by-step explanation:
The expression for the area in terms of the width is:
A
=
w
2
+
7
w
When
w
=
12
, the area is
228
units.
Explanation:
We know that the formula for the area of a rectangle is:
Area = length x width
A
=
l
w
In this specific case, though, we are told that the length is
7
units greater than the width:
l
=
w
+
7
We can substitute this value for
l
into our area formula, and then there will be only one variable on the right-hand side:
A
=
l
w
=
(
w
+
7
)
w
=
w
2
+
7
w
This expression is the answer to the final sentence in the question, asking us to write an expression for
A
in terms only of
w
.
Now we can use our expression to find the area in the situation where
w
=
12
:
A
=
w
2
+
7
w
=
12
