what is the answer to this
3a+2b-a-3b
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.

2.3×10⁹=(1×10³)(2.3×10^n)
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

1. During which parts of the graph does Arthur’s distance from home decrease?
2. When is Arthur waiting for bagels? Explain how you know.
3. If Arthur’s pace had not been constant after leaving the bagel shop, which part of the graph would change? Explain how that part of the graph would change.
Answer:
1. During part 2. The y-axis (line going up) represents his distance. At part 1, his distance stays the same because he is sitting in the park. At part 2 we see the line go down, which means his distance from home is decreasing.
2.At part 3. His distance stays the same, which represents him waiting in line. We know this because the line stays at the same distance and the time increases(this is the x-axis)
3. There would be another part of the graph. If he had stopped again, there would have been another straight line with the distance the same and the time increasing.

Linda's Video Store sold three times as many
Titanic tapes as Godzilla tapes. The price of a
Titanic tape is $20 and the price of a Godzilla
tape is $15. If her total sales for these tapes was
$2250, what is the total number of cach video that
she sold?
Answer:
T=90 G=30
Step-by-step explanation:
T=3G
20T+15G=2250
20(3G)+15G=2250
60G+15G=2250
75G=2250
Divide by 75
G=30
T=90 3(30)

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)

Find from first principles the derivative of cos x
Answer:
Please see the explanation.
Step-by-step explanation:
Let
[tex]f\left(x\right)=cosx[/tex]
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]
[tex]=\lim _{h\to 0}\left(\frac{cos\:\left(x+h\right)-cos\:x}{h}\right)[/tex]
[tex]=\lim _{h\to 0}\left[\frac{cos\:x\:cos\:h-sin\:x\:sin\:h\:-\:cos\:x}{h}\right][/tex]
[tex]=\lim _{h\to 0}\left[\frac{-cos\:x\left(1-cos\:h\right)-sin\:x\:sin\:h\:}{h}\right][/tex]
[tex]=\lim _{h\to 0}\left[\frac{-cos\:x\left(1-cos\:h\right)\:}{h}-\frac{sin\:x\:sin\:h}{h}\right][/tex]
[tex]=-cosx\:\left(\lim \:_{h\to \:0\:}\frac{1-cos\:h}{h}\right)-sin\:x\:\lim \:\:_{h\to \:\:0}\:\left(\frac{sin\:h}{h}\right)[/tex]
[tex]=-cosx\:\left(0\right)-sinx\left(1\right)[/tex]

At time t=0 hours, a tank contains 3000 litres of water. Water leaks from the tank. At the end of every hour there is x% less water in the tank than at the start of the hour. The volume of water, in litres, in the tank at time t hours is Vt. Given that Vt=KtV0 V2=2881.2 work out the value of k and the value of x.
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
Suppose 2,400 spectators attend at leas one game this soccer season. Use ther survey data to estimate the number of spectators who attended 5 or more games this season
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
Jane needs $150 for the hot air balloon ride. She already has $45 and she can earn the rest by working 12 hours at her job. If h represents her hourly earnings, which of the following equations can be solved to find
Jane's hourly earnings? Circle two correct equations.
150 = 12h
12 = 150 - h
150 = 45 + 12h
150 + 45 = 12h
150 = 12h + 45
