Answer:

Step-by-step explanation:
Represent the sofa with S and the love seat with L.
So, we have:
--- Total Cost

Required
Determine the value of L
Substitute 2L for S in the first equation.


Divide both sides by 3



<em>Hence, a love seat costs 117.0</em>
<em></em>
<u>Using Graph</u>
See attachment for graph
S is plotted on the y-axis and L is on the x-axis.
The green line represents
while the orange line represents 
When the line of the graph is traced to the x-axis, we have:

Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Here you go. just put the equation into a table
Answer:
Length = 14 inches
Width = 3 inches
Step-by-step explanation:
length * width = area
(x + 8 ) (x - 3) = 42
Use FOIL method
x*x - x*3 + 8*x - 8*3 = 42
x² -3x + 8x - 24 = 42
x² + 5x - 24 - 42 = 0
x² + 5x - 66 = 0
Sum = 5
Product = 66
Factors = 11 , (-6)
x² + 5x -66 = 0
x² + 11x - 6x - 6*11 =0
x(x + 11) - 6(x + 11) = 0
(x + 11) (x -6) = 0
x + 11 is ignored because length and width will not have negative value.
x - 6 = 0
x = 6
Length = x + 8 = 6 + 8 = 14 inches
Width = x - 3 = 6 - 3 = 3 inches
The experimental probability so far is 19/34, since she made 19 good shots out of 34.
So, based on this results, and until new updates arrive, we can assume that she makes point with probability 19/34.
