Answer: Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
Step-by-step explanation: (8b-4r)-(2b-r)
Open the bracket
=8b-4r-2b+r
Collect the like terms and simplify
=8b-2b-4r+r
=6b-3r
Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.

Answer:
C) y = 2x +8
Equation of the straight line passing through the point (-2,4) and having slope m =2
y = 2x +8
Step-by-step explanation:
<em>Step(i):-</em>
<em>Given that the points are (-2,4) and (6,20)</em>
<em>The slope of the line</em>
<em> m = </em><em></em>
<em> m =2</em>
<u><em>Step(ii):-</em></u>
Equation of the straight line passing through the point (-2,4) and having slope m =2
y - 4 = 2( x-(-2))
y = 4 + 2x +4
y = 2x +8

Answer:

Step-by-step explanation:
In Store A the price of mayonnaise went down from $5.82 to $5.23.
Total decrease in mayonnaise price in Store A = $5.82-$5.23 = $0.59
In Store B the price of mayonnaise went down from $8.77 to $2.43.
Total decrease in mayonnaise price in Store A = $8.77-$2.43 = $6.34
In Store C the price of mayonnaise went down from $8.71 to $3.64.
Total decrease in mayonnaise price in Store A = $8.71-$3.64 = $5.07
Cumulative decrease in mayonnaise price across all stores:
$0.59 + $6.34 + $5.07 = $12
Average decrease in mayonnaise price across all stores =
= $4
