Help! Exponential Equation WITHOUT CALCULATOR

ale4655 [162]

$
1.
(2^{x} -2^{-x})^{2} = 4^{2} \\ \\2^{2x}-2*2^{x}*2^{-x} + 2^{-2x} =4^{2} \\ \\2^{2x}-2*2^{x-x} + 2^{-2x} =4^{2} \\ \\ 2^{2x}+ 2^{-2x} - 2=16 \\ \\ 2^{2x}+ 2^{-2x} = 18

\\ \\ 2.( 2^{x})^{3} - (2^{-x}^) ^{3}= (2^{x} -2^{-x})(2^{2x}+2^{x}*2^{-x}+2^{-2x})
\\ \\ ( 2^{x})^{3} - (2^{-x}^)^{3}=(2^{x} -2^{-x})(2^{2x}+2^{-2x}+2^{x}*2^{-x})
\\ \\ ( 2^{x})^{3} - (2^{-x}^)^{3}=(2^{x} -2^{-x})(2^{2x}+2^{-2x}+1)
\\ \\ ( 2^{x})^{3} - (2^{-x}^)^{3}=(2^{x} -2^{-x})((2^{2x}+2^{-2x})+1)
$

$\\ \\ ( 2^{x})^{3} - (2^{-x})^{3} =(4)((18)+1)= 76
\\ \\ 2^{3x}-2^{-3x} =76

A printer will produce Katie wedding invitations for $210. The price to produce 120 invitations is $290. The printer uses a line

VMariaS [17]

Thank you for asking this question. Here is your answer:

M = y2 - y1/x2 - X1 = M

= 290 - 210/120 - 80

M = 80/40

M = 2

Now we will consider y intercept

y = mx + b

210 = 2(80) + b

210 = 160 + b

b = 210 - 160

= 50

Now we will combine everything in order to get the answer.

y = 2x + 50

y = 2(60) + 50

y = 120 + 50

y = 170

So the final answer for this question is $170.

If there is any confusion please leave a comment below.
