Answer:

Step-by-step explanation:2a-b

Answer:

2a-b

Step-by-step explanation:

We can start by grouping our A's and B's, while making sure to keep their individual signs.

For our A's, we get 3a-a and for our B's, we get 2b-3b.

When we simplify our A's, we get 2a and when we simplify our B's, we get -b.

After grouping them back together, you end up with 2a-b.

Parallel

Step-by-step explanation:

If you graph these on a graph the beginning part is the same however the second part (the 2 and 30) are different which would just show how far to space the lines because those are  the y-intercept and the fraction part is the slope

Answer:

This is a really complicated variable for me. I am very good at math though.

Step-by-step explanation:

Answer:

x = 2; K = 0.98

Step-by-step explanation:

At time, t = 0, Volume of Water = 3,000 litres

After t hours , the Volume of water in the tank = Vt

At the end of every hour there is a x% less water in the tank then at the start of the hour

After 1 hour, volume of water left Vt = V1

V1 = 3,000 - 3000 × (x/100)

V1 = 3,000 - 30x

After 2 hours, Volume of water left is V2

V2 = (3,000 - 30 x) - (3,000 - 30 x) × (x/100)

V2 = (3,000 - 30 x) - (3000x - 30x²)/100

V2 = {100(3000 - 30x) - x(3000 - 30x)} /100

V2 = {(3000 - 30x)(100 - x)}/100

Recall, V2 = 2881.2

Therefore

{(3000 - 30x)(100 - x)}/100 = 2881.2

(3000 - 30x)(100 - x) = 288120

300000 - 3000 x - 3000 x + 30 x² = 288120

30 x ² - 6000 x + 11880 = 0

Dividing both sides by 30

x² - 200 x + 396=0

Factorizing:

(x -198)(x-2) = 0

x = 198 or x = 2

Since the percentage by which the water reduces cannot be greater than 100, x = 2 is chosen.

Step 2: Solving for k

Given that Vt=KtV0

K = Vt/V0

At t = 1

V1 = 3000 - 30x

V1 = 3000 - 30 × 2

V1 = 3000 - 60

V1 = 2940

K = 2940/3000

K = 0.98

Answer:

y = -x - 4

Step-by-step explanation:

Plug in the point and slope into the equation y = mx + b, and solve for b:

y = mx + b

-6 = -1(2) + b

-6 = -2 + b

-4 = b

Then, plug in b and the slope into y = mx + b

y = -1x - 4

y = -x - 4 is the equation of the line

Answer:

5 1/4

Step-by-step explanation:

Answer:

C) (0,5)

Step-by-step explanation:

f(x) is y and x is x

The table is providing you with points

y-y over x-x gives you a slope of -5

Use the points and turn it into a point-slope equation and convert to y-intercept equation

y-15=-5(x+2)

y-15=-5x-10

y=-5x+5

So the y-intercept is 5 or (0,5)

Answer:

Step-by-step explanation:

Answer:

800 spectators

Step-by-step explanation:

Using the survey provided above, we can see that the survey population is a total of 150 spectators by adding up all of the spectators. Since only 50 spectators attended 5 or more games then that means that the percentage of the survey population that attended 5 or more games is ...

50 / 150 = 0.3333 or 33.33%

Therefore, if we are supposing that 2,400 spectators attended at least one game this season then we can multiply this population by the percentage of people who tend to attend 5 or more games in order to actually calculate the total number of people who will attend 5 or more games this season.

2,400 * 0.3333 = 800 spectators

By the first principle

[tex]f\:'\left(x\right)=\lim _{h\to 0}\left(\frac{f\left(x+h\right)-f\left(x\right)}{h}\right)[/tex]

Answer:

n = 6

Step-by-step explanation:

2.3 × [tex]10^{9}[/tex] = (1 × 10³)(2.3 × [tex]10^{n}[/tex] )

(1 × 10³)(2.3 × [tex]10^{n}[/tex] ) = (1)(2.3) × (10³)( [tex]10^{n}[/tex] ) = 2.3 × [tex]10^{3+n}[/tex]

2.3 × [tex]10^{3+n}[/tex] = 2.3 × [tex]10^{9}[/tex] ⇒ 3 + n = 9 ⇒ n = 6

Answer:

x = 5 which mean that if you replace 5 with the x you will get 90 as your answer.

Step-by-step explanation:

Answer:

x=5

Step-by-step explanation:

∠17x+5≅∠18x

17x-18x=-5

-x=-5

x=5

17x5+5=90°

18x=90°

13x - 14 = -118

13x = -104

x = -8

Answer:

28!

Step-by-step explanation:

28 - 18 = 10,

10 x -2 = -20

Answer:

11<x

x>11

first u subtract 4 on both sides

which leaves u with 11 on the left and x on the right

I think It's 11 I'm not sure
