R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
Answer :
2x - y = 7
-y = -2x + 7
y = 2x - 7 <— slope-intercept form

Answer:
see explanation
Step-by-step explanation:
Using the cofunction identities
tan(90 - A) = cotA and cscA = sec(90- A)
Consider the left side
tanA + tan(90 - A)
= tanA + cotA
=
+ 
= 
= 
=
× 
= secA × cscA
= secA. sec(90 - A) = right side ⇒ verified
Answer:
Eleanor and Peter's total income
= $597.63
Step-by-step explanation:
Eleanor's Income:
Paycheck = $380.48
Eleanor's Expenses:
Birthday gift= $16.50
Peter's income
Paycheck = $120
Sales of his college textbook = $13.65
Check from Peter's father= $100
Peter's total income =Paycheck + Sales of his college textbook + Check from Peter's father
= $120 + $13.65 + $100
= $233.65
Eleanor and Peter's total income
= Eleanor's Income + Peter's total income - Eleanor's Expenses
= $233.65 + $380.48 - $16.50
= $597.63
Eleanor and Peter's total income
= $597.63
