Answer:
B and C
Step-by-step explanation:
They're congruent
Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...
Answer:
Step-by-step explanation:
f(x) = 2x - 5
When x = -2,
f(-2) = 2*(-2) - 5 = - 4-5 = (-9)
When x = 0,
f(0) = 2*0 - 5 = -5
When x = 5,
f(5) = 2*5 - 5 = 10 - 5 = 5
x -2 0 5
y -9 -5 5
Answer:
infinite solutions
Step-by-step explanation:
-9(x+3) +12 = -3(2x+5)-3x
Distribute
-9x-27 +12 = -6x-15-3x
Combine like terms
-9x -15 = -9x-15
Add 9x to each side
-9x-15+9x = -9x-15+9x
-15 = -15
This is a true statement so it is true for all x
