Answer:
y =
x + 
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 )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
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, 7) into the partial equation
7 =
+ c ⇒ c = 7 -
= 
y =
x +
← equation of line
Answer:
64
Step-by-step explanation:
(3x+5)^2 = ax^2 +bx+c
FOIL the left side
(3x+5) (3x+5)
9x^2 +15x+15x+25
Combine like terms
9x^2 +30x+25
a=9
b= 30
c= 25
a+b+c = 9+30+25 = 64
9/8 x 250 = 281 1/4 or 281.25
1 1/6 x 250 = 291 2/3 or <span>291.66</span>
