Hi there!

f(x) = -2x - 3
Plug in 0 for "x" to solve for f(0):
f(0) = -2(0) - 3
f(0) = -3
Since the question is asking you to evaluate f(0) - 7, simply subtract:
-3 - 7 = -10.
Answer:
Emily can deduct $1975 for medical expenses.
Step-by-step explanation:
Emily is itemizing deductions on her federal income tax return and had $5200. Her AGI was $43,000.
We have:
The AGI is =$43,000
Medical expenses amount = $5200
If medical expenses are deductible to the extent that they exceed 7.5% or 0.075 of a taxpayer’s AGI, means = 43,000 * 0.075 = $3225
Now the deductible amount is = $5200 - $3225 = $ 1975
<em>Hence,Emily can deduct $1975 for medical expenses.</em>
