You know that D is 35° cause of the angle next to F. and <E=180-(120+35) so E is 25°
Answer:
f(-7)=0.
f(2)=-9/5.
f(3) doesn't exist because 3 isn't in the domain of the function.
Step-by-step explanation:
is the given function.
We are asked to find:


.
f(-7) means to replace x in the expression called f with -7:
Evaluate
at 



So f(-7)=0.
f(2) means to replace x in the expression called f with 2:
Evaluate
at 



So f(2)=-9/5
f(3) means to replace x in the expression called f with 3:
Evaluate
at 


Division by 0 is not allowed so 3 is not in the domain of our function.
♠Answer♠
Now , X = √( 40² + 9² )
√(1600 + 81)
√1681
41

Since line AB is multiplied by 3 to get line XY, you would multiply 2 by 3 to get 6. The answer is J, or 6. Hope this helps!
<span> Add x to both lenght and width and you get 25+x and 10+x. Set up equation with new area </span>
<span>(25+X)(10+X)=1000 </span>
<span>solve using quadratic formula
