The answer is y=3 since there is no slope so the value of x will not affect your graph
Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
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
Answer:
a = 9
b = 2
Step-by-step explanation:
Given : a = 9
a = b + 7
9 = b + 7
b = 9 - 7 = 2
