Use the formula SA=a+1/2ps
a=area of the base
p= perimeter of the base
s= slant height
Usually when the line is going down the slope will be represented as a negative number. Remember rise/run. The slope of this line would be -2/2. If it needs to be simplified it would be -1. If answer choices are all positive best bet would be 1! Hope this helps!
Answer:
B.
Step-by-step explanation:
The easiest way is to substitute 8 for x in the first equation,
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.
