5x-4=-20
Answer:
y = 
Step-by-step explanation:
Given
Ry - wy = t ← factor out y from each term on the left side
y(R - w) = t ( divide both sides by (R - w ) )
y = 
Answer:
Ok y= 2x + b
b referring to any number less than -2 and more than -2
so y=2x+4 can work
Step-by-step explanation:
parallel lines in slope-intercept form have the same slope, i.e. the same 'm' value or coefficient of <em>x</em><em> </em> but different interceptions
Answer:
d) 9 years
Step-by-step explanation:
let present age as 'x'.
then, x=2x-3(x-6)
x=2x-3x+18
x= -x+18
2x=18
x=18/2
x=9
Answer:
BC= 2√5
CD= 2√10
DE= 2√5
BE= 2√10
slope of BC = 2
slope of CD = 1/3
slope of DE = 2
slope of BE = 1/3
Step-by-step explanation:
formula for distance = √(x2-x1)²+(y2-y1)²
formula for slope = (y2-y1)/(x2-x1)
