At firt we should solve what is h(0)
h(0)=0^2+2
h(0)=2
So then you should take the h(0) answer to g(x) and the result is g(2)= -2-5=-7
A=adult
c=children
total lumber=30
total number=adults+children
a+c=30
total cost=50
total cost=acost+ccost
acost=a times cost per adult=a times 3=3a
ccost=c times cost per child=c tiems 1=1c=c
total cost=3a+c
50=3a+c
equiaotn are
a+c=30
3a+c=50
multiplyu first by -1 and add
3a-a+c-c=50-30
2a=20
a=10
sub
10+c=30
c=20
answer is A
Answer:
See explanation below
Step-by-step explanation:
When solving a linear inequality, the main difference resides in the following:
When we change the signs of the terms (either from positive to negative or from negative to positive) we have to change the sign of the inequality (if the sign was ≥, we change it to ≤, if the sign was ≤, we change it to ≥). Therefore we have to be more careful while doing this.
