1.
yes
x is number of group acts
y is number of indivual acts


2. I would eliminate x by multiplying 2nd equation by -3 then adding

12x+6y=120
<u>-12x-3y=-90 +
</u>0x+3y=30

3y=30
divide by 3
y=10

sub
4x+y=30
4x+10=30
4x=20
divide 4
x=5

each group act takes 5 mins and each individual takes 10 minutes

If the equation of the line y = 2x - 6 is changed to y = -2x - 6, how is the graph changed?
-Dominant- [34]

Answer:

from sloping up to sloping down ⇒ answer D

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

* Now lets solve the problem

∵ The equation of the line is y = 2x - 6

∵ The equation is changed to y = -2x - 6

- If the both signs of x and the number are changed means the

 equation is multiplied by -1

∴ The line is reflected across the x-axis

- If the sign of x only is changed

∴ The line is reflected across the y-axis

- From the equation 2x changed to -2x, but -6 not changed

∴ The sign of x only changed

∴ The line is reflected across the y-axis

* The graph is reflected across the y-axis

∴ from sloping up to sloping down
