Given two functions f(x)=2x+1 and g(x)=−13x−3 , what is the function rule for (f+g)(x)

Answer:

A will appear to the left of B.  The answer is B) hope this helps

Step-by-step explanation:

If A < B, A will appear to the left of B on the number line.

A number line is a linear line on which points are marked equidistant from each other and used to represent the position of a certain linear number on it.

Let us take an example where A = 2 and B = 3. Here 2 < 3.

We know that 2 is to the left of 3 on the number line.

Now let us take an example of negative numbers. A = -3 and B = -2.

Here, -3 < -2. - 3 is also to the left of - 2.

Therefore we can say that A is always to the left of B.

Therefore, if A < B, A will appear to the left of B on the number line.

Answer:

9.42 feet

Step-by-step explanation:

The distance around the edge of a circle is called the circumference.  The formula for circumference is C = dπ   where d is the diameter.  We are given

d = 3, so we have C = 3π.  We are told to use 3.14 for pi, so we have

C = 3(3.14) = 9.42

Answer:

csc^2(theta)

Step-by-step explanation:

Answer:

-1050

Step-by-step explanation:

I know the answer because descending means going down so 2100 is the big number and its negative to if you do -2100 divided by 2 then you will get -1050.

The equation to represent the submarine's elevation and time is elevation = 2100 - (rate of descent × 2).

To represent the submarine's elevation and time, we can use the equation:

elevation = starting altitude - (rate of descent ×  time)

Where:

In this case, the equation would be:

elevation = 2100 - (rate of descent × 2)

Answer: OPTION B

Step-by-step explanation:

Let's call:

c: the number of cars.

m: the number of motorcycles.

Based on the given information, you can set up the following system of equations:

[tex]\left \{ {{c+m=38} \atop {4c+2m=104}} \right.[/tex]

You can solve it by the Elimination method:

- Multiply the first equation by -4.

- Add both equations to cancel out the variable "c".

- Solve for "m":

[tex]\left \{ {(-4)(c+m)=38(-4)} \atop {4c+2m=104}} \right.\\\\\left \{ {-4c-4m=-152} \atop {4c+2m=104}} \right.\\-------\\-2m=-48\\m=24[/tex]

(24 motorcycles)

 - Substitute m=24 into any of the original equations ans solve for "c". Then:

[tex]c+24=38\\c=38-24\\c=14[/tex]

(14 cars)

The answer is:

Option B.

[tex]Cars=14\\Motorcycles=24[/tex]

We know that the total of tires of all the vehicles was 104, and there were 38 vehicles with 4 tires and motorcyles with 2 tires, so, we can calculate how many cars and motorcyles participated in the ride using the following equation:

Let x be the cars and y be the motorcyles, so:

[tex]x+y=38[/tex]

and,

[tex]4x+2y=104[/tex]

So, isolating x in terms of y from the first equation, we have:

[tex]x=38-y[/tex]

Then, substituting "x" into the second equation we have:

[tex]4(38-y)+2y=104\\152-4y+2y=104\\152-2y=104\\2y=152-104\\2y=48\\y=\frac{48}{2}=24[/tex]

Now, substituting "y" into the first equation, we have:

[tex]x+24=38[/tex]

[tex]x=38-24=14[/tex]

So, there were a total of 14 cars and 24 motorcycles in the ride.

Answer:

soda = 35mg

coffee = 81mg

energy = 83mg

Step-by-step explanation:

coffee + energy + soda = 199

coffee = 11 + (2 * soda)

energy = (soda + coffee) - 33

(11 + (2 * soda)) + ((soda + (11 + (2 * soda))) - 33) + soda = 199

11 + 2s + s + 11 + 2s - 33 + s = 199

22 + 6s - 33 = 199

-11 + 6s = 199

6s = 210

s = 35

soda = 35mg

c  = 11 + 2s

c = 11 + 2(35)

c = 11 + 70

c = 81

coffee = 81mg

e = s + c - 33

e = (35) + (81) - 33

e = 116 - 33

e = 83

energy = 83mg

Final answer:

One serving of soda contains 35 mg of caffeine, one serving of coffee contains 81 mg of caffeine, and one serving of energy drink contains 83 mg of caffeine.

Explanation:

Let's solve this problem step by step:

To find the value of x, we can set up an equation:

Simplifying the equation:

Combine like terms:

Add 11 to both sides:

Divide both sides by 6:

Therefore, one serving of soda contains 35 mg of caffeine. Substituting this value into the previous equations:

Final answer:

The area of a triangular poster with a base of 2 1/2 feet and a height of 1 3/4 feet is calculated using the formula A = 1/2 × base × height, resulting in an area of 2.1875 square feet.

Explanation:

To find the area of a triangle, we use the formula A = ½ × base × height. Given that the base of the triangle is 2 1/2 feet (which is 2.5 feet when converted to a decimal) and the height is 1 3/4 feet (which is 1.75 feet in decimal), we can calculate the area as follows:

A = ½ × base × height

A = ½ × 2.5 ft × 1.75 ft

A = ½ × 4.375 ft²

A = 2.1875 ft²

Therefore, the area of the poster is 2.1875 square feet.

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

x² + (y - 4)² = 25 ← is in standard form

with centre = (h, k) = (0, 4) → A

here (h, k) = ( 9, - 5) and r = 1, hence
