Answer:
8 animal balloons
Step-by-step explanation:
Using equivalent ratios, or a proportion, you can solve for the number of animal balloons that clown can create in 6 minutes:
Now, set the simplified ratio equal to the time of 6 minutes and the variable of 'b' to equal the number of balloons:
To get equivalent fractions, the numerator and denominator must be multiplied by the same factor:
8 animal balloons in 6 minutes
Remark
Good thing you tried to answer the question. At lease we know how to proceed.
A is wrong, because you can draw a conclusion.
B Remember that CD is constructed so that AB is cut in half. So the distance from CD to B is the same distance as CD to A. Choice B is true.
C is incorrect. CD can be extended to any length as long as CD goes through the point where the two arcs above and below AB meet are joined by C and D, then CD can be any length. In order words, CD can be any length.
D Doesn't have to be. See the answer for C.

Answer:
g(-3)=9
Step-by-step explanation:
Replace all of the (x) with -3
So the new equation
g(-3)= -2(-3)+3
Now simplify
g(-3)= 6+3
Simplify further
g(-3)= 9
Hope this helps!
Answer:
Induction is done by demonstrating that if the condition is true for some n then it must also be true for n+1. If you then show that the condition is true for n=0 then it must be true for all n>0. For this problem:
Step 1: n=1
The sum of the first 1 odd numbers is 1. 12=1. Therefore the condition holds for n=1.
Step 2: induction
If the sum of the first n odd numbers is n2 then the sum of the first n+1 integers is n2+(2n+1)=(n+1)(n+1)=(n+1)2
So the condition is also true for n+1.
Step 3: conclusion
Since the we have shown that the condition is true for n=1 and we have shown that if it is true for n then it is also true for n+1 then it follows by induction that it is true for all n≥1.
