<h3>What is a linear equation?</h3>
Linear equation are equation in which the highest power of the variable is equals to 1.
Suzan is saving money to buy a bike . She already have $63 and is going to save an additional $9 per week. The cost of the bike is $198.
Let
w = number of weeks
The linear equation that can be used to represent the situation using 9, w and 163 is as follows:
using the slope-intercept form,
y = mx + b
where
m = slope
b = y-intercept
Therefore,
The solved equation to find the number of weeks is as follows:
- 9w = 198 - 63
- 9w = 135
- w = 135 / 9
- w = 15

Find how fast she runs 1 km:
18/2 = 9 minutes.
So we know have K = 9t
Subtract 18 from both sides:
K-18 = 9t -18
Rewrite the right side:
K-18 = 9(t-2)
Loge 70.81 = a
Log to the base e is also written as ln
ln 70.81 = a
