Answer:

m= 3 b= -2

Step-by-step explanation:

The formula is y=mx+b

Plugging in the numbers, we get y=3x-2. When we change the subtraction to addition, we get y=3x+ -2.

Therefore, your answers are m=3 and b= -2

Hope this is helpful to you!

Connie keeps her sports card collection in a 54-page book. Each page has 9 slots for cards.

vesna_86 [32]

Answer:

324 slots.

Step-by-step explanation:

If there is 9 slots per page, and 18 pages in the 54 page book are taken up by football cards, that leaves you with 36 pages left. Again, 9 slots per page, so you multiply 9 x 36 and get 324 slots available for baseball cards.

Complete the table of values for this absolute value function. Then use the drawing tool(s) to graph the function. F(x)-2|x+1|-1

rusak2 [61]

Answer:

Please check the explanation!

Step-by-step explanation:

Given the equation

$f\left(x\right)=-2|x+1|-1$

As some of the absolute rules are:

$\left|a\right|=a,\:a\ge 0$

$\:|-a|=a,\:\quad \:a>0$

NOW, let us solve!

Let us substitute all the table values

Putting x = -4

$y=-2\left|-4+1\right|-1$ ∵ $\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0$

$y=-6-1$

$y=-7$

So, when x = -4, then y = -7

Putting x = -3

$y=-2|-3+1|-1\:$

$y=-4-1$

$y=-5$

when x = -3, then y = -5

Putting x = -2

$y=-2\left|-2+1\right|-1$

$y=-2-1$

$y=-3$

when x = -2, then y = -3

Putting x = -1

$y=-2\left|-1+1\right|-1$

$y=-0-1$

$y=-1$

when x = -1, then y = -1

Putting x = 0

$y=-2\left|0+1\right|-1$

$y=-2-1$

$y=-3$

when x = 0, then y = -3

Putting x = 1

$y=-2\left|1+1\right|-1$

$y=-4-1$

$y=-5$

when x = 1, then y = -5

The graph is also attached below.

The cruise boat can carry up to 45 passengers. The company wants to know the minimum number of passengers needed per cruise to c

denpristay [2]

Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640

Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14

Sales income
Average ticket $ 36 .40

Break-even point = (fixed costs) 
(income per passenger – costs per passenger) 


Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
