F(x) = - 55x + 330
The domain is the set of possible input-values, i.e. x-values.
You know that f(x) cannot bebigger than 330 not lower than zero, then construct the inequality:
0 ≤ f(x) ≤ 330
0 ≤ - 55x + 330 ≤ 330
Multilply by - 1 and change the inequality signs:
0 ≥ 55x - 330 ≥ -330
Add 330 to all the members
330 ≥ 55x ≥ 0
Divide by 55
6 ≥ x ≥ 0 => 0 ≤ x ≤ 6
The the possible x-values (practical domain) is all the real numbers between 0 and 6 inclusive.
Answer:
4250
Step-by-step explanation:
The decimal points have to be moved 3 times because of the number of 0s in 1000
Type2
i.a=120°
ii.x=130°
iii.a=60°
iv.x=60°
y=50°
type3
i.a=120°
ii.a=80°
iii.2a+3a=180
5a=180
a=36°
iv.a=120°
b=360-110-60-120=70°
50%.
120 students minus 60 males means there are 60 females.
60/120 = 50%
Answer:
Step-by-step explanation:
100% divided by 4 is 25%
25 books were 1/4 of the books total.
the other 3/4 would be 75%
they og ordered 100 books
