This is the concept of algebra, to get the difference of the expression given we proceed as follows;
(k^2-9k+20)-(k^2-9k+20)
collecting like terms we get:
(k^2-5k^2)+(-9k-9k)+(20-20)
=-4k^2-18k+0
=-4k^2-18k
The answer is (-4k^2-18k)
Step-by-step explanation:
Step 1: Write down the percent divied by 100 like this: percent/100
Step 2: If the percent is not a whole number, then multiple both top and bottom by 10 for every number after the decimal point. (for example, if there is on number after the decimal, then use 10, if there are two then use 100, ect.)
Step 3: simplify.(or reduce) the fraction
Answer:
Step-by-step explanation:
A proportional relationship has equation:
where k is the constant of proportionality.
Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.
We substitute k=-10 into the equation to get:
Therefore the correct choice is
The answer Is 32 Because anything in absolute value with a negative ends positive.
