Question

I need help. Please explain everything I need to know in order to answer this.

Answer 1

x=-8

Step-by-step explanation

`f(x)=-(1)/(2)x+6`

Step 1

there is a value for x , that when you replace it inthe equation you obtain 10,then

`\begin{gathered} f(x)=-(1)/(2)x+6=10 \\ -(1)/(2)x+6=10 \end{gathered}`

Step 2

solve for x

`\begin{gathered} \text{isolate x} \\ -(1)/(2)x+6=10 \\ \text{subtract 6 in both sides} \\ -(1)/(2)x+6-6=10-6 \\ -(1)/(2)x=4 \\ \mu ltiply\text{ each side by -2} \\ -(1)/(2)x\cdot-2=4\cdot-2 \\ x=-8 \end{gathered}`

so, the answer is x=-8
