c. \( (50,20) \) d. \( (0,100) \) e. \( (10,36) \)

3) \( -5 x-7=-2 \)

(1 point) Find all solutions \( x \) to each of the following equations. Separate multiple answers with commas. Use no solution or none if there are no solutions. \( 2^{x}=7 \) has solutions \( x=\square \) Hint: Webwork doesn't allow specifying the base of the logarithm, but you can use: \( \log _{B}(C)=\log (C) / \log (B) \) \( 5 \cdot 2^{x}=7 \) has solutions \( x=\square \) \( 5 \cdot 2^{x}+10=17 \) has solutions \( x=\square \) \( e^{x}=7 \) has solutions \( x=\square \) \( 5 \cdot e^{x}=7 \) has solutions \( x=\square \) \( 5 \cdot e^{x}+10=17 \) has solutions \( x=\square \)
