Answer:
<em>y=7x+1</em>
Step-by-step explanation:
<u>Linear modeling</u>
Consists of finding a linear equation that represents a situation in real life.
Jenny starts her stamps collection with only 1 stamp.
Then she collects 7 stamps per day.
Let's call
y=total amount of stamps in Jenny's collection
x=number of days
Knowing Jenny collects 7 stamps per day, then in x days, she collects 7x stamps. The total amount can be obtained by adding the first stamp she had. Thus, the model is:
y=7x+1
2464829438
The next number is 2,464,829,439
Answer:30
Step-by-step explanation:
Answer: 3
The first two zeros are not sig figs, but the next three zeros are sig figs
Answer:
(0 , 1), (4, 9).
Step-by-step explanation:
y = x2 – 2x+1
y = 2x+1
Substitute y = 2x + 1 into the first equation.
2x + 1 = x^2 - 2x + 1
x^2 - 2x - 2x = 0
x^2 - 4x = 0
x(x - 4) = 0
x = 0, 4.
When x = 0, y = 1.
When x = 4, y = 8 + 1 = 9.
