Ok use why they told you.
17=A+B+C & A=B-3 &C=2+B
we only what to work with one variable at a time.
lucky for us we have an idea of what "A" & "C" are. we can plug those into our first equation respectively.
SOLVE FOR B
17= (B-3)+B+(2+B)
17=B-3+B+2+B
17=3B-1
17+1=3B
18=3B
18/3=B
6=B (this means he won 6 B titles)
SOLVE FOR A
A=B-3
A=6-3
A=3
SOLVE FOR C
C=2+B
C=2+6
C=8
CHECK
17=A+B+C
17=3+6+8
17=17
1. 1,450:24. Then simplify: 725:12 or D.
2. 3:1.8 is the answer :)
The curve passes through y-axis at
Substituting
into
we have:
The y-intercept is -24
Answer:
(3, $42)
\
Step-by-step explanation:
Geraldo gets paid the same hourly rate from day to day. This rate is the slope of the line representing his earnings. It is m = rise/run, which here is
m = $84/(6 hr), or m = $14/hr. Thus, the equation representing his earnings is y = ($14/hr)x.
The ordered pair (3, $42) satisfies this equation. None of the other three do.
