Answer: x=4 and x=4
Step-by-step explanation:
Steps: (325000 - 243000) / 243000 * 100
82000 / 243000 * 100
0.337449 * 100
33.7449
Answer: 33.7449%
Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
The linear function that tells the temperature, c, of the compound t minutes after 9:00 a.m. is given by:
c(t) = 10 + 0.8t
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- Initially, at 9:00 a.m., the temperature is of 10 degrees celsius, hence b = 10.
- In 15 minutes, the temperature increased by 12 degrees, hence the slope is of m = 12/15 = 0.8.
Hence, the function is:
c(t) = 10 + 0.8t
