There are 20 boys in the class. The ratio is 4:3 so that means 4 out of 7 are boys and 3 out of 7 are girls. Divide 35 by 7 and you get 5. 5 times 4 is 20. 5 times 3 is 15. add them together and you have 35 students in total. So 20 students are boys and 15 students are girls.
Answer:
D. Ernesto
Step-by-step explanation:
12 - (-10) - 5 x 3
12 - (-10) - 15
12 + 10 - 15
First make x the subject of the relation:-
f(x) = 2x - 4
2x = f(x) + 4
x = (f(x) + 4) / 2
Now replace x by the inverse f-1(x) and f(x) by x :-
f-1(x) = (x + 4) / 2
Answer:
y <= -2x + 1
