Y=40+5x
For an example, say Mia wanted to add $5 into her account each week for 2 weeks.
y=40+5(2)
5(2)=10
y=40+10
y=50
Mia will have a total of $50 in her account if she added $5 for each week for 2 weeks. Same for Juan, his equation will be based off his amount y=15+10x
Answer:
-3n²+n³
Step-by-step explanation:
Since the unknown number is n;
Product of the number and negative three is -3n
square of the number is n²
Taking their sum;
Sum = -3n + n²
Hence the sum of the product of the number and negative three and the square of the number is -3n+n²
If a number n is multiplied by the sum of the product of the number and negative three and the square of the number, hence the required function is;
f(n) = n(-3n + n²)
Expand
f(n) = -3n²+n³
This gives the required function
Answer:
Step-by-step explanation:
Remark
This is just a matter of adding 2 fractions and reducing the result
Givens
f1 = 3/12
f2 = 1/12
Equation
Answer = f1 + f2
Solution
answer = 3/12 + 1/12
The denominators are the same. The answer will have the same denominator
Answer = (3 + 1)/12
Answer = 4 / 12
The answer has a common factor in both the top and bottom of the fraction (4 is the common factor).
Therefore divide the top and bottom by 4
Answer = 4/4 // 12/4
Answer = 1 / 3
