The equation of line a is y= -8/5x + 4/3 line b is perpendicular to a what is th slope of line b

The slope of line b is  

Step-by-step explanation:

∵ The equation of line a is y = x +

→ Compare it with the form of the equation above to find m

∴ m =

∴ The slope of the line a is  

∵ Line b is perpendicular to line h

∴ The product of their slopes = -1

→ To find the slope of b reciprocal the slope of line a and change its sign

∵ The reciprocal of and opposite sign of   is

∴ The slope of line b is  

To check your answer multiply the slopes they must give you -1

∵  ×    = -1

∴ The answer is correct

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
