60% is 93.49$ but u are getting 100$ discount so 2nd is ans
Answer:
5 terms
Step-by-step explanation:
nth term of the sequence =n^2 + 20
an= n^2 + 20
1st term when n= 1
1^2 + 20= 20
2nd term n= 2
2^2 + 20=24
3rd term when n= 3
3^2 + 20= 29
4th term when n= 4
4^2 + 20= 36
5th term when n= 5
5^2 + 20 =45
6th term when n= 6
6^2 + 20=56
Hence, terms in the sequence are less than 50 are first 5 terms
SOLUTION
Write out the equation

To solve this system of equation, the aprropriate method will be substitution
Substitute the expression for y into the second equation for y, we have

Expand the paranthesis we have

Divide both sides by 4, we have

Since the value of x has been obtained, we substitute into the first equation

Therefore
x = -3, y= -4
