Answers

Answer 1
Answer:

Answer:

f(-6) = -49

Step-by-step explanation:

f(-6) = -(-6)^2 - 13 = -(36) - 13 = -49.

Blue Skies Equipment Company uses the aging approach to estimate bad debt expense at the end of each accounting year. Credit sales occur frequently on terms n/60. The balance of each account receivable is aged on the basis of three time periods as follows: (1) not yet due, (2) up to one year past due, and (3) more than one year past due. Experience has shown that for each age group, the average loss rate on the amount of the receivable at year-end due to uncollectibility is (a) 3 percent, (b) 9 percent, and (c) 28 percent, respectively. At December 31, 2019 (end of the current accounting year), the Accounts Receivable balance was $48,700 and the Allowance for Doubtful Accounts balance was $920 (credit). In determining which accounts have been paid, the company applies collections to the oldest sales first.

State an equation you could use to find the value of x. Then find the value of x in simplest form.

Answers

You can use the Pythagorean Theorem:

a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)

So the equation is 2x^2=98 (simplest form) and x=7

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a bicycle is on sale at $12 more than half of the regular price and the selling price is $75.

The regular price of the bicycle will be calculated as below:-

( P / 2 ) + 12 = 75

P  + 24 = 150

P = 150 - 24

P = 126

Therefore, the regular price of the bicycle will be $126.

89
97

Answers

The answer is 89 because you distribute the 8 to the 10 and then to the 9. 80+9=89
152 because 8x10=80 and 8x9=72 so 80+73=152
