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

Answer:</h2>
By process of elimination, we can eliminate:
- <em>A:</em> <em>y = 3x - 1</em>
- <em>C: y = 3x + 1</em>
- <em>B: y = -3x</em>
<em>A and C</em> don't work because the given line has it's y-intercept at the origin, therefore, no y-intercept is written. <em>B </em>is not it either because the line <em>does not</em> go <em>down</em> from <em>left to right</em>, therefore, the slope is <em>not</em> negative.
The answer is <em>D: y = 3x</em> because since the line goes <em>up</em> from <em>left to right</em>, the slope is positive, and the y-intercept is the origin, so the equation will have no b.
Step-by-step explanation:
6) D= [-1,4]
R= [-2,3]
7) D= [-3,4]
R= [-5,7]
8) i do not know how to read this...
Hello :
for exemple ; x = 3t+2 y = -2t +7
