C

$12
If the cost c is at least $12 then it could be equal to 12, or could also be a cost greater than $12. So, c is greater than or equal to 12, expressed as <span>c

$12</span>
Step-by-step explanation:
X + Y = -3
X + 3x +5 = -3
X=-2
X+Y=-3
Y=-3+2
Y=-1
Answer:
The answer to your question is y = x - 23
Step-by-step explanation:
Process
1.- Get the slope of the line
If two lines are parallels, it means that they have the same slope.
y = 1x - 10
Slope = m = 1
2.- Get the equation of the line
y - y1 = m(x - x1)
y + 29 = 1(x + 6) Substitution
y + 29 = x + 6 Expanding
y = x + 6 - 29 Simplifying
y = x - 23
9+4+7+3+10+9=42
42÷6= 34.5. I believe "mean" is the same as avgerage.
