b= 1/2
perpendicular slopes are those that are opposite signs and reciprocal of the original given slope
We take the function as a sequence
Term 1 ⇒ 5
Term 2 ⇒ 4
Term 3 ⇒ 3.2
Between terms, there is a common ratio of ⁴/₅
We get it from here:
Term 2 / Term 1 =

Term 3 / Term 2 =

=

When a sequence has a common ratio between term, the sequence is a Geometric Sequence

Where

is the first term,

is the common ratio, and

is the term number
We have:

and

The formula for the function is
Answer: He bought 1 magazine and 3 comic books.
Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.

Percentage of students who offered burger = 40%
The answer to this is no solution because it is in simplest form.
3x²-x+1 and 2x²+5x-4 can not be factored anymore. The expression given was in simplest form and could not be factored anymore. A trinomial expression is the form of ax²+bx+c. Factoring trinomials help you to put the equation in simplest form.
I hope this helps!!!!!
