y=2x+6
y=2x+2
Solve y=2x+6 for y
Substitute 2x+6 for y in y=2x+2
y=2x+2
2x+6=2x+2
Add -2x to both sides
2x+6-2x= 2x+2-2x
6=2
Add -6 to both sides
6-6=2-6
0=-4

OK so for the first one, you have 3 TVs for 1200 dollars. The 90 dollars is a 1 time cost. so what u want to do is multiply 3 by 1200 and then add 90.
Answer:
33333 x 166667 = 5555511111
I think that is the answer you wanted
Step-by-step explanation:
166667
x 33333
<u>5555511111 </u>
Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them
2x²+9x-16x-72
2x²-7x-72
The question is asking for the lower bound of the 95% two tailed Confidence interval of the normally distributed population.
95% C.I. is given by 200 + or - 1.96(25) = 200 + or - 49 = (151, 249)
Therefore, the minimum weight of the middle 95% of players is 151 pounds.
