What’s the explicit equation for 100, 80, 60, 40

Answers

Answer:

20

Step-by-step explanation:

To find the explicit equation for an arithmetic sequence, we can use the formula:

a_n = a_1 + d(n - 1)

where a_n is the n-th term of the sequence, a_1 is the first term of the sequence, and d is the common difference. Plugging in the values for this sequence, we get:

a_n = 100 + (-20)(n - 1)

Simplifying, we get:

a_n = 120 - 20n

This is the explicit equation for the sequence 100, 80, 60, 40, … You can use this equation to find any term of the sequence by plugging in the value of n. For example, to find the fifth term of the sequence, you can plug in n = 5 and get:

a_5 = 120 - 20(5) = 120 - 100 = 20

Amanda’s dad is twice as old as she is today. The sum of their ages is 66. Find the ages of Amanda and her dad.

Answers

Let amanda's age be x and her dad's age be y.

Amanda’s dad is twice as old as she,  therefore 2x=y

The sum of their ages is 66, therefore x+y=66

x+y=66

2x=y,

substitute.

2x+x=66

3x=66

Divide.

x=22.

plug it back in, 22+y=66, y=44.

Amanda's age is 22 and her dad's age is 44.
