Answer:
x - 9
Step-by-step explanation:
(f ÷ g)(x) = f(x) ÷ g(x), that is
← factorise the numerator
= 
← cancel the common factor (x - 10) on numerator/denominator
= x - 9
Answer:
b = 24 meter
Step-by-step explanation:
Using Pythagoras theorem:
a² + b² = c²
Here given: a = 10 m, b = ?, c = 26 m
<u>Insert values</u>
10² + b² = 26²
b² = 26² - 10²
b² = 676 - 100
b² = 576
b = √576
b = 24
Answer: infinitely many solutions
Step-by-step explanation: A system of two equations can be classified as follows:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer: 0.09
Step-by-step explanation:
From the question, in a physical education class, there are 21 boys and 9 girls. Each day, the teacher randomly selects a team captain randomly.
The probability that the team captain will be a girl two days in a row assuming no student is absent will be:
Boys = 21
Girls = 9
Total = 21 + 9 = 30
P(pick a girl) = 9/30 = 3/10 = 0.3
P(pick a girl 2 days in a row) = (0.3)²
= 0.09
Answer:
34
Step-by-step explanation:
because line BC divides line DA and line AE into parts with the same ratio to each other (since BC is parallel to DE). This means that (42/21)*17 will give us the length of AB, when we do so, we get 34 as the length of AB.
