Answer: Slope is 1 because if we have x by itself, we assume it is only one.

y-intercept because according to the slope intercept formula, (y=mx+b), it is in the correct spot.

A digital camera for 249.99 at 4%sales tax

Answers

1) Before tax = $249.99
100% = 1 = 249.99
4% = 0.04
100% + 4% = 104% = 1.04 multiplier
1.04 x $249.99 = $259.9896 =  $259.99 After Tax

2) After tax = $249.99
100% = 1
4% = 0.04
1 + 0.04 = 1.04
104% = $249.99
$249.99 / 1.04 = $240.375 = $240.38 Before Tax
Sales tax is: $249.99* (4/100)

$249.99+ $249.99* (4/100)= $259.99

The price after tax is $259.99~

4x -30≥ - 3x + 12    

add 30 to bot size

4x - 30 + 30 ≥ -3x + 12 + 30

simplify

4x  ≥ -3x +  42

add 3x to bot  sides

4x +3x ≥ -3x+42+3x

simplify

7x ≥ 42

divide   bot sides by 7

7x/7 ≥ 42/7

simplify

Multiply and simplify the product. 2i(4 – 5i)

Answers

Answer:

10 + 8i.

Step-by-step explanation:

2i(4 – 5i)     Distribute the 2i:

= 2i*4 + 2i * -5i

= 8i - 10i^2          Note i^2 = - 1 so we have:

8i - 10* -1

= 8i + 10

= 10 + 8i.

mark has 312 books in his bookcases. He has 11 times as many fiction books as nonfiction books. How many fiction books does Mark have? please tell me how you got answer step by step? thank you

Answers

Answer: 286


Step-by-step explanation:

Let the number of non fiction books be 'x'

Then the number of fiction books = 11x

Total books in Mark's bookcase= 312

According to the given situation the equation will be

x+11x=312\n\Rightarrow12x=312..............[\text{combine like terms}]\n\Rightarrow\ x=26.......[\text{divide 12 on both sides}]

Hence, the number of non fiction books=26

and the number of Fiction books =11*26=286

Let number of non/fraction books =x
Then number of fiction books=11x
So, we form the equation x+11x=312
12x=312 x=26 so mark has 26*11=286 fiction books
