I 2x +1 I < -4

Answers

the absolute value of a number is always positive. Therefore you cannot have an absolute value equal to a negative number.

the answer would be "no solution"

To increase an amount by 3% what single multiplier would you use

Answers

The multiplier would be 1.03 because 1 is a whole and you are increasing by 3 therefore the answer would be 1.03

If you were decreasing an amount then you would take that amount away from 100. Eg - decrease an amount by 50%. What multiplier would you use? The answer to this would be 0.50 because you are taking away 50 from 100.

Hope this helps :)

Dan pays £714.73 a year in his car insurance. The insurance company reduces the price by 4.1%. How much does the insurance cost now? Give your answer to 2 DP.

Answers

Answer:

£682.57

Step-by-step explanation:

Dan pays £714.73 a year in his car insurance.

The price was reduced by 4.1%

To find the new cost of the insurance, we simply need to find 4.15% of £714.73 and then subtract that from the initial price of the insurance (£714.73)

4.5% of 714.73 is:

$(4.5)/(100) * 714.73$ = £32.16

Then, the cost of the insurance now is:

£714.73 - £32.16 = £682.57

The insurance now costs £682.57

Final answer:

To calculate the new price of the insurance, we first calculate the discount, which is 4.1% of the original price (£714.73). Then, subtract this discount from the original price. Understanding percentage reduction is fundamental in calculating such discounts.

Explanation:

To calculate the new cost of car insurance, we will subtract the 4.1% reduction from the original price of £714.73. The percentage reduction can be calculated using the formula: Discount = Original Price x (Percentage / 100).

In our case, the discount is given by: Discount = £714.73 x (4.1 / 100).

Then, we subtract this discount from the original price to obtain the new price of insurance: New Price = Original Price - Discount.

Insurance premiums are a significant factor in personal finance, but factors like discounts can make them more affordable. It is crucial to understand the concept of percentage reductions to comprehend how discounts significantly affect the final cost for services such as insurance.

Help please! absolute value equations!

Answers

Answer:

n = -1 n = -7

Step-by-step explanation:

5| 2n+8| +3 = 33

Subtract 3 from each side

5| 2n+8| +3-3 = 33-3

5| 2n+8| = 30

Divide by 5

5/5| 2n+8| = 30/5

| 2n+8| = 6

An absolute value equation has two solutions, one positive and one negative

2n+8 = 6 2n+8 = -6

Subtract 8 from each side

2n+8-8=6-8 2n+8-8 = -6-8

2n = -2 2n = -14

Divide by 2

2n/2 = -2/2 2n/2 = -14/2

n = -1 n = -7

Solve the following system of equations . Enter the y-coordinate of the solution . Round your answer to the nearest tenth. 5x+2y =7. -2x+6y=9

Answers

5x + 2y = 7
multiplying this equation by 2
10x + 4y = 14 ...(A)

-2x + 6y = 9
multiplying this equation by 5
-10x + 30y = 45 ... (B)

Add (A) and (B),
10x-10x + 4y +30y = 14+45

0 + 34y = 59

y = 59/34
y = 1.7
