Answer:
Step-by-step explanation:
<u>Given:</u>
- Tickets cost $12 at the door, number of tickets d
- Tickets cost $8.50 if purchased in advance, number of tickets a
- Minimum target from tickets sold $1050
<h3>Part 1</h3>
<u>Required inequality to meet the goal:</u>
<h3>Part 2</h3>
<u>If a = 36 then minimum value of d:</u>
- 12d + 36*8.5 ≥ 1050
- 12d + 306 ≥ 1050
- 12d ≥ 1050 - 306
- 12d ≥ 744
- d ≥ 744/12
- d ≥ 62
Minimum 62 tickets must sell
The slope intercept form is
y=ax+b
So
11x-2y=-6 /+2y
11x=2y-6 /+6 both sides
11x+6=2y (changing sides)
2y=11x+6 /:2 divide by 2 both sides
y=
- its the result
Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8
Answer:
no if the diameter was 7.2 inches the circumstance would be 22.62 :)
