Answer:
4.7
Step-by-step explanation:
the median is the middle number in a set of numbers so first we need to put them in order
1.9 3.4 [4.7] 6.5 7.6
this one is easy since we have an odd number of digits
the answer is 4.7
Graphs can be used to represent functions.
See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>
The function is given as: 
When k = 1,
We have:
----- substitution property of equations
So, the equation is: when k = 1
When k = 0.4,
We have:
----- substitution property of equations
So, the equation is: when k = 0.4
When k = -1,
We have:
----- substitution property of equations
So, the equation is: when k = -1
See attachment for the graphs of: , and

Answer:
The right answer is the last option, 12,12.
Step-by-step explanation:
Given:
12 rectangular planks
2 sides per plank
Length = 8 ft
Width = 3 ft
Area of a rectangle = Length * Width.
A = 8ft * 3ft
A = 24 ft²
24 ft² x 2 sides of a plank = 48 ft²
48 ft²/plank * 12 planks = 576 ft² is the total area Alex needs to varnish.
576 ft² ÷ 125 ft² = 4.608 pint or round to 5 pints
5 pints x $3.50/pint = $17.50 Total cost that Alex need to spend to varnish all the wooden planks.
10x+4-2x+4
= 8x+8
If you want the x
8x=-8
X=-1
