Sagot :

[tex]64\text{ = 0.025x + 7 (option B)}[/tex]Explanation:[tex]8=-\sqrt[]{0.025x+7}[/tex]

To determine the next step, we need to slove the expression.

divide both sides by -1:

[tex]\begin{gathered} \frac{8}{-1}=\frac{-\sqrt[]{0.025x+7}}{-1} \\ -8=\sqrt{0.025x +7} \end{gathered}[/tex]

Square both sides of the equation:

[tex]\begin{gathered} 8^2=(\sqrt{0.025x +7})^2 \\ 64\text{ = 0.025x + 7 } \\ 64\text{ - 7 = 0.025x } \\ 57\text{ = 0.025x } \\ Hence,\text{the missing step: }64\text{ = 0.025x + 7 (option B)} \end{gathered}[/tex]
