I think that it is b sorry if I’m wrong
the initial equation is:

So we can solve the equation to find the possible solution of the equation so:

So the only possible solution of the equation is 6, so solution is option C
Single solution.
They have different slopes and must therefore have 1 solution.
<em>f(-5) = 15 (A)</em>
- Step-by-step explanation:
<em>f(x) = - 2x + 5</em>
<em>replace x = - 5</em>
<em>f(-5) = -2(-5) + 5
</em>
<em>(-)(-) = +
</em>
<em>f(-5) = 10 + 5
</em>
<em>f(-5) = 15 (A)</em>
