Step-by-step explanation:

$given \\ (x + \frac{1}{x} ) = 7 \\ now \\ (x + \frac{1}{x} ) ^{2} \\ (7) ^{2} (given) \\ 49 \\ again \\ {x}^{2} + ( \frac{1}{x} ) ^{2} \\ (x + \frac{1}{x}) ^{2} - 2 \times x \times \frac{1}{x} \\ (7) ^{2} - 2 \\ 49 - 2 \\ 47$

3. Tmobile charges 100 dollars for the initial phone line and then 20 dollars for every phone line afterwards.

salantis [7]

A)your equation for t-mobile would be
y=20x+100

Topar equation
y=30x

B) you’d set the two equation equal to each other

20x+100=30x

giving you the answer x=10

C) when x>13

D) when x<14

i’m a bit iffy on the last two but that’s the conclusion i came to
