99×5/100=4.95
99+4.95=103.95
Answer:
y = 1/2x -2
Step-by-step explanation:
The slope of the equation is over 1 and to the right by 2 so Rise/run = 1/2
The y-intercept is -2
Answer:
7x + 3y = 44
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides
7y = 3x + 5 ( divide all terms by 7 )
y =
x +
← in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = -
+ c ⇒ c = 3 +
= 
y = -
x +
← in slope- intercept form
Multiply through by 3
3y = - 7x + 44 ( add 7x to both sides )
7x + 3y = 44 ← in standard form
