First one.
tan(pi/2) is the asymptote, and 2pi/4*x = pi/2*x, between 0<x<2, goes from 0 to pi, so it only passes thru pi/2.
FIRST one
Answer:
x=−7
Step-by-step explanation:
(x+4)(2)−3(x+4)−3=0
(x)(2)+(4)(2)+(−3)(x)+(−3)(4)+−3=0(Distribute)
2x+8+−3x+−12+−3=0
(2x+−3x)+(8+−12+−3)=0(Combine Like Terms)
−x+−7=0
61 is the composite Number your welcome
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:
