Clara simplifies (8b--r) and says the result is 6b-5r what error did clara make? a. clara incorrectly combined the b coefficients. the correctly simplified expression is 10b-5r b. clara incorrectly combined the r coefficients. the correctly simplified expression is 6b-3r c. clara incorrectly combined the r coefficients. the correctly simplified expression is 6b-5r d. clara incorrectly combined the b coefficients. the correctly simplified expression is-10b-5r pls 7 minutes remaining..

The correct answer is A. She incorrectly combined the b coefficients. The only symbols that have an effect on a number is the symbol BEFORE the number. Thus, in 2b-r, they would separate into 2b and -r.

Using this knowledge, combine like terms the right way.

8b+2b=10b

-4r-r=-5r

The correct equation is 10b-5r

Hope this helps!

B. Clara incorrectly combined the r coefficients. The correctly simplified expression is 6b-3r

Step-by-step explanation:

Simplifying the expression by opening the brackets we get:

8b - 4r-2b+r

A negative coefficient multiplied by a negative coefficient results to a positive coefficient.

Combining like terms together:

8b-2b-4r+r

=6b-3r

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

there is no graph so i cant sorry
