Answer:
There are 2 variables in the equation. The variables are y and n
You can isolate r to one side of the equation by dividing by adding three, dividing by s, multiplying by a and you get:
r=a(3+k)/s
Answer: 4 m
Step-by-step explanation:
Let the amount each dimension was increased by be x.
Now we can set up a equation.
(2+x)(4+x) = 48
8 + 2x + 4x + x^2 = 48
x^2 + 6x - 40 = 0.
We can factor the left side of the equation.
(x+10)(x-4) = 0.
Therefore, x equals either -10 or 4. Since you can't increase a dimension by a negative amount, x must equal to 4.
The correct answer is option B which is the function will be
f(n) = -6.25+0.75n.
<h3>What is a function?</h3>
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given series is as follows:-
-5.5, -4.75, -4, -3.25, ...
When we use the function:-
f(n) = - 6.25 + 0.75n
f(1) = -6.25 + 0.75 x 1 = -5.5
f(2) = -6.25 + 0.75 x 2 = -4.75
f(3) = -6.25 + 0.75 x 2.25 = -4
Therefore the correct answer is option B which is the function will be
f(n) = -6.25+0.75n.
