Answer:
x > 10
Step-by-step explanation:
The inequality is -12x + 3y > 9.
PART A:
The sytem has no solution if inequality does not share a common area. The inequality -12x + 3y > 9 consist the region to left of line -12x + 3y = 9. So for no solution the region to left of equation -12x + 3y = 9 is suitable.
Thus inequality for no solution is, -12x + 3y < 9.
PART B:
For infinite solution the region of both inequality must overlap each other, or the inequality is same with some multiplication of divison factor. So inequality for infinite many solutions is,
Thus inequality for infinite many solution is 12x - 3y < -9.
Answer:
She will buy at least 10 pounds or more.
Step-by-step explanation:
If each pound costs $4 and she is spending $40 worth, she needs to buy 10 pounds in order to spend the minimum of $40. She can buy more than 10 pounds to keep spending more money. 11, 12, 13, 14, 15, and so forth are all possible numbers in pounds she will buy.
Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A = ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
