Answer:
1 meter to centimeters: 1 meter x 100
1 meter to kilometers: 1 meter ÷ 1,000
Step-by-step explanation:
The first equation, 8x - 9y = - 23
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = ( , 3) and (x₂, y₂ ) = (- 4, - 1 )
m = = (- 4)/- =
partial equation is y = x + c
to find c substitute either of the 2 points into the partial equation
using (- 4, - 1 ), then
- 1 = - + c ⇒ c =
y = x + ← in slope- intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearrange the slope- intercept equation into this form
multiply through by 9
9y = 8x + 23 ( subtract 9y and 23 from both sides )
8x - 9y = - 23 in standard form

Answer:
$262.50
Step-by-step explanation:
7 Months is approximately 30 weeks.
25 x 30 = $750
10% = $75
5% = $37.50
60% = (75x6) = $450
$450 + $37.50 = $487.50
$750 - $487.50 = $262.50
