Answer:
Up to 10
Step-by-step explanation:
- Cost of fish = $3.99
- Limit of money = $40
- Number of fish = x
<u>Inequality:</u>
- 3.99x ≤ 40
- x ≤ 40/3.99
- x ≤ 10.02
Answer:
Step-by-step explanation:
= x - 5 ( x ≥ 3 )
(
)² = ( x - 5 )²
x - 3 = x² - 10x + 25
x² - 11x + 28 = 0
(x - 4)(x - 7) = 0
= 7
= 4
Check the answer:
1). x = 7
= 7 - 2
√4 = 2
2 = 2
2). x = 4
= 4 - 5
1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.
Answer:
21, 34, 55
Step-by-step explanation:
13+8=21
21+13=34
34+21=55
Given the stated equation we know that that quadratic formula has 2 as its degree. This meats it has 2 roots. A linear equation has a degree of 1. A linear equation has 1 root. To know if they intersect, the must have one root in common. To know this, solve the two equation simultaneously. If they result to an answer then they intersect.
6. No, the conclusions wrong because 20 out of 50 peoples favourite is drawing which means 20/50 which equals 0.4 times 100 which is 40% not 60%
7. Yes, the conclusion is right because 5/50 is equal to 0.1 times 100 which is 10%
