To solve this problem,
⇒ must use PEMDAS and fractional conversions
⇒ I attached an image of what is PEMDAS below
Let's solve:
[tex]2(x+7)-18x+\frac{4}{5} =2x+14-18x+\frac{4}{5} =14-16x+\frac{4}{5}[/tex]
Here we convert 14 into a fraction with a denominator of 5 so that we
can add it to 4/5
[tex]14*1-16x+\frac{4}{5} =14*\frac{5}{5} -16x+\frac{4}{5} =*\frac{14*5}{5} -16x+\frac{4}{5} \\=\frac{70}{5} -16x+\frac{4}{5} =\frac{70}{5} +\frac{4}{5} -16x=\frac{70+4}{5}-16x\\ =\frac{74}{5} -16x=-16+\frac{74}{5} \\=-16+\frac{74}{5}[/tex]
Answer: Thus the expression equivalent to the function given is (C)
Hope that helps!
