M = y2 - y1/x2 - x1
m = 4 — -4/6 - 8
m = 8/-2
m = 4/-1
m = -4

Parallel slopes are the same

m = -4
b = ?

Replace x and y values of the point into slope intercept formula
y = mx + b
-9 = -4(2) + b
-9 = -8 + b
-9 + 8 = b
b = -1

Write final equation
y = -4x - 1

Step-by-step explanation:

Agent B sold the highest number (53.85% ) of houses given the number of listed houses.

Find the percentage of houses each agent sold.

For A

x/100 * 150 = 75

cross multiply and find x, that would be 50%

For B

x/100 * 130 = 70

cross multiply and find x, that would be 53.85%

for C

x/100 *145 = 75

cross multiply and find x, that would be 51.72%

Which equation has no solution?
seropon [69]

An equation with no solution will be an equation when simplified, will be an false statement.


1st option: 4(x+3)+2x=6(x+2)


Firstly, foil 4(x+3) and 6(x+2). 4x+12+2x=6x+12


Next, combine like terms. 6x+12=6x+12


Next, subtract 6x and 12 on both sides of the equation, and your answer will be 0 = 0. Because this is a true statement, the 1st option is incorrect.



2nd Option: 5+2(3+2x)=x+3(x+1)


Firstly, foil 2(3+2x) and 3(x+1). 5+6+4x=x+3x+3


Next, combine like terms: 11+4x=4x+3


Next, subtract 4x on each side of the equation to get 11\neq3 . Since this is a false statement, this option has no solution. This is the correct option.
