Step-by-step explanation:

Answer: (f+g)(x)=x²-x-3

Step-by-step explanation:

(f+g)(x) means f(x)+g(x). Since we are given f(x) and g(x), we can add them together.

(f+g)(x)=2x-1+x²-3x-2                [combine like terms]

(f+g)(x)=x²-x-3

Now, we know that (f+g)(x)=x²-x-3.

Answer:

x=20°

Step-by-step explanation:

This is actually simpler than it seems. Try redrawing (or maybe just imagine) that the only inscribed angle is x with the two lines going to the 40°. If we let 40°=θ, then: x=θ/2

This is actually true for any situation with inscribed angles, so you could use this to find w, y, and z as well.

Anyways x=(40°)/2=20°, so x=20°

Answer:

C. 10.4 million liters.

Step-by-step explanation:

1. First, you want to create an equation to help you solve this.  You know that there are 5,000 school buses and they use 40 liters of fuel per week.  So, you know that 5,000 · 40x would be the amount of fuel for x weeks (where x is the number of weeks).

2. To figure out how many liters would be used in 52 weeks, simply put 52 in for x.  So, the expression is 5,000·40(52).

3.  Multiply 40(52) to get 2,080.  Your expression now looks like this: 5,000·2,080

4. Multiply 5,000(2,080) to get your answer of 10,400,000 liters.

Answer:

2 and 178

Step-by-step explanation:

If we take an instance of a number 'x', according to the question we find that x+x*89=180(Because they are complementary)

We get, = 89x+x=180

=> 90x=180

=> x=180/90

=> x =2

So, we found that x=2 , hence the other angle is going to be 2*89=178

This is correct as 2+178=180(as they are supplementary to each other)

Hope this answer helps, Please mark me as brainliest, Thank you!

Answer:

Step-by-step explanation:

The two-point form of the equation of a line is useful for this.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  q = (195500 -98000)/(6.00 -2.55)(p -2.55) +98000

  q = 97500/3.45(p -2.55) +98000

  q ≈ 28269.9p +25934.8

__

For a supply of 145000, the price would need to be ...

  145000 = 28269.9p +25934.8

  119065 = 28270p

  119065/28270 = p = 4.21

A price of $4.21 will result in a supply of $145,000.

__

The slope is the additional amount supplied for each dollar increase in price.

__

The price value that results in a supply of zero is ...

  0 = 28270p +25935

  -25935 = 28270p

  -25935/28270 = p ≈ -0.92

The p-intercept is about -$0.92.

y+5=2(x-6)

y+5=2x-12

y=2x-17

Answer:

Step-by-step explanation:

2y = x + 11

y = 1/2x + 11/2

perp. -2

y + 5 = -2(x - 6)

y + 5 = -2x + 12

y = -2x + 7

Answer:

500 markers

Step-by-step explanation:

Multiply 5000 by 1/10

[tex]5000*\frac{1}{10} \\\\= \frac{5000}{10}\\[/tex]

Simplify (dividing the numerator and denominator by 10)

[tex]\frac{5000}{10} \\= \frac{500}{1}\\= 500[/tex]

Answer:

2,6,18,54

How I got this answer:

Each term after the first is found by multiplying by a fixed, non-zero number called a common ratio.

step by step:

2×3=6

6×3=18

18×3=54

The common ratio is 3.

Answer:

The confidence interval will decrease

Step-by-step explanation:

Generally the confidence interval is mathematically represented as

[tex]\= x \pm z_c * \frac{s}{\sqrt{n} }[/tex]

Here [tex]z_c[/tex] is called the critical value of [tex]\frac{level \ of \ significance }{2}[/tex] obtained from the normal distribution table , s is the standard deviation , n is the sample size (number of measurements )

Now looking at the formula we that if the increase the sample size that the confidence level would decrease

So if the n is increased to 10  

   The  confidence interval would decrease

Answer:

Step-by-step explanation:

[tex]20 - \frac{x}{3} = \frac{x}{2} [/tex]

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

[tex]6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x[/tex]

Using the addition property add 2x to both sides of the equation

That's

[tex]3x + 2x = 120 + 2x - 2x \\ 5x = 120[/tex]

Divide both sides by 5

[tex] \frac{5x}{5} = \frac{120}{5} [/tex]

We have the final answer as

Hope this helps you

Answer:

C

Step-by-step explanation:

The only possible outcomes on a standard number cube (aka a die or dice) are {1,2,3,4,5,6}

It is not possible to roll a 7 or larger, so we say the probability is 0. A probability of 0 means "impossible".

Answer:

200,000

Step-by-step explanation:

Answer:

$65

Step-by-step explanation:

So we already determined that the total cost C to drive m miles is:

[tex]C=0.25m+40[/tex]

And we want to find the total cost of driving 100 miles.

So, substitute 100 for m and solve for C:

[tex]C=0.25(100)+40[/tex]

Multiply:

[tex]C=25+40[/tex]

Add:

[tex]C=\$ 65[/tex]

Therefore, it will cost $65 to drive 100 miles.
