Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.
Answer:
-8(8-7a)
Step-by-step explanation:
56a-64=-8(8-7a)
1. 2 as 4 x 2 is 8 and 4 x 8 is 32 so 32 + 8 = 40
The answer to your question is...
60 times more than a minute!
Answer:
2 weeks
Step-by-step explanation:
Given in the question that,
Equation that represent Lisa's total amount of money
f(x) = 20 - 13x
Equation that represent Joey's total amount of money
g(x) = x² - 10
To find weeks, x, after which they will have same amount of money, we will equate both equation
<h3>20 - 13x = x² - 10</h3>
x² - 10 - 20 + 13x = 0
x² - 30 + 13x = 0
x² + 13x - 30 = 0
(x - 2)(x + 15) = 0
x = 2 or x = -15
Weeks, x, can not be negative so we will reject x = -15
Hence, after 2nd week Lisa and Joey will have the same amount of money save.
