Answer: [tex]\frac{x+5}{x+3}[/tex]
Step-by-step explanation:
The problem gives you the following expression:
[tex]\frac{x}{x+3}+\frac{3}{x+3}+\frac{2}{x+3}[/tex]
Therefore, to add the fractions with equal denominator, you must rewrite the denominator (x+3) and add the numerators of each one of the fractions.
Then, keeping the above on mind, you obtain the sum shown below (You must remember to add the like terms):
[tex]\frac{x+3+2}{x+3}=\frac{x+5}{x+3}[/tex]
Answer:
The correct answer is (x + 5)/(x + 3)
Step-by-step explanation:
It is given an expression,
x/x+3 + 3/x+3 + 2/x+3
From the above expression we can see that, sum of three fractions
To find the sum
The above expression is sum of three fraction. The denominators are same which is (x + 3)
So we can add numerators
x/x+3 + 3/x+3 + 2/x+3 = ( x + 3 + 2)/(x + 3) = (x + 5)/(x + 3)
Therefore the correct answer is (x + 5)/(x + 3)
a darts competition starts at 6:25, the competition lasts for three and a quarter hours. which watch face displays the time that competition endes ?
They’re aren’t any pictures you provided but I can still assist you a little. It’s starts at 6:25 so you add 3 hours then add 15 minutes.
So add 6 hours + 3 hours = 9 hours, then do 25+15 = 40
So the competition ends at 9:40

Your answer is 5 gallons
Answer:
5
Step-by-step explanation:
1/4 has 3 x's, so we multiply 1/4 by 3 to get 3/4. 3/8 has 2 x's so we multiply 3/8 with 2 to get 3/4. 5/8 has 4 x's, so we multiply 5/8 by 4 to get 10/4. 1 has 1 x so we multiply 1 with 1 to get 1. Adding these up, we get 3/4 + 3/4 + 10/4 + 1 = 16/4 + 1 = 5.

if f(x)=2x-7, then find f(8)
Final answer:
To find f(8) for f(x) = 2x - 7, plug 8 into the equation and simplify: f(8) = 2(8) - 7, which equals 9.
Explanation:
To find the value of the function f(x) at x = 8, you simply substitute the value of 8 into the function. Given f(x) = 2x - 7, substituting 8 for x gives us:
f(8) = 2(8) - 7
Now, multiply 2 by 8:
f(8) = 16 - 7
Then, subtract 7 from 16:
f(8) = 9
Therefore, the value of the function f(x) when x = 8 is 9.

What are the various methods of solving systems of equations and how do we find the solutions(s)?
Answer:
1-ELIMINATION.
2- SUBSTITUTION.
3- GRAPHING.
Step-by-step explanation:
Methods:
1- Elimination:
- Line up the variables.
- To cancel out one of the variables, you need to make that the coefficient of that variable opposite. For example:
[tex]\left \{ {{3x+y=1} \atop {-3x+4y=3}} \right.[/tex]
As you can see, the coefficient of x in the first eqation is 3 and -3 in the second option.
- Add the equations.
- Solve for the the variable that is still present.
- Substitute the value of the variable obtained into one of the original equations.
- Solve for the other variable.
2- Substitution:
- Solve for one of the variables from any of the equations of the system.
- Substitute into the other equation for that variable.
- Solve for the other varible to find its value.
- Substitute the value obtained into any of the original equations and solve for the other variable.
3- Graphing:
- Rewrite the equations as equtions of the line slope intercept form ([tex]y=mx+b[/tex], where m is the slope nd b the y-intercept).
- Graph each line.
- Then:
If there ir an intersection point of the two lines, then that point is the solution to the system
If the lines are the same, there are infinitely many solutions.
If the lines are parallel, then there is no solution

Write an equation in slope-intercept form for the graph of the line shown???????
the answer is y=3x-1
the 3 comes from the point moving 3 up and 1 right and the -1 comes from the y intercept
Answer:
y = 3x - 1Step-by-step explanation:
The slope-intercept form of the equation of a line:
y = mx + b
m - slope
b - y-intercept
From the graph we have the y-intercept: (0, -1). Therefore b = -1.
y = mx - 1
From the graph we have the second point (1, 2). Put the coordinates of this point to the eqution:
2 = m(1) - 1
2 = m - 1 add 1 to both sides
3 = m
Finally we have
y = 3x - 1
evaluate f(x) = 1/3 x for x = 4
The answer is:
[tex]f(4)=\frac{4}{3}[/tex]
Why?Evaluating a function means substituting the variable (x in this case) by the given value (4 in this case), so where is an "x" we should rewrite with the number 4.
So, evaluating the function for [tex]x=4[/tex] we have:
[tex]f(4)=\frac{1}{3}(4)=\frac{1}{3}*4=\frac{4}{3}[/tex]
Have a nice day!
Answer: [tex]f(4)=\frac{4}{3}[/tex]
Step-by-step explanation:
To solve the problem shown above, you only need to substitute x=4 into the given fucntion.
By definition, the value of x (which is this case is 4) is called the input value and the value obtained when you susbtitute it into the function is called the output value.
Keeping the above on mind when you susbtitute x=4 into the function, you obtain the result shown below:
[tex]f(x)=\frac{1}{3}x\\\\f(4)=\frac{1}{3}(4)\\\\f(4)=\frac{4}{3}[/tex]

[tex]\bf \begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\\\ x&-\frac{3\pi }{10} \end{array}\implies \cfrac{180}{x}=\cfrac{\pi }{~~-\frac{3\pi }{10}~~}\implies \cfrac{180}{x}=\cfrac{\frac{\pi}{1} }{~~-\frac{3\pi }{10}~~} \\\\\\ \cfrac{180}{x}=\cfrac{\pi }{1}\cdot \cfrac{10}{-3\pi }\implies \cfrac{180}{x}=-\cfrac{10}{3}\implies 540=-10x\implies \cfrac{540}{-10}=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill -54=x~\hfill[/tex]
What is the surface area of the triangular prism?
[Not drawn to scale]
54 square feet
67.5 square feet
81 square feet
85.5 square feet
Answer:
The answer is the third
The surface area of prism = 81 ft²
Step-by-step explanation:
∵ The triangular prism has 5 faces
- Two triangles ⇒ bases
- 3 rectangles ⇒ side faces
* to find the surface area of it, we will find the area of
each face and add them together
- Area of bases:
∵ The bases are right angle triangles with base 6 ft and height 4.5 ft
∵ Area triangle = 1/2 × base × height
∴ Area one base = 1/2 × 6 × 4.5 = 13.5 ft²
∴ Area two bases = 13.5 × 2 = 27 ft² ⇒ (1)
- Area of the first rectangle with dimensions 3 ft and 6 ft
∵ Area rectangle = L × W
∴ Area 1st rectangle = 3 × 6 = 18 ft² ⇒ (2)
- Area of the second rectangle with dimensions 3 ft and 7.5 ft
∴ Area 2nd rectangle = 3 × 7.5 = 22.5 ft² ⇒ (3)
- Area of the third rectangle with dimensions 3 ft and 4.5 ft
∴ Area 3rd rectangle = 3 × 4.5 = 13.5 ft² ⇒ (4)
Add (1) , (2) , (3) and (4)
∴ The surface area of prism = 27 + 18 + 22.5 + 13.5 = 81 ft²

based on the graph below, how would you describe the curve?
Answer:
It's A.
Step-by-step explanation:
For every value of x there is one value of y - we can draw a vertical line through any value of x and it will pass through only one value of y.
Therefore it is a one-to-one function.
Answer:
Option A
Step-by-step explanation:
The curve given is an increasing curve cutting x axis once and y axis once.
Any vertical line cuts only once the curve. Hence this is a function only.
We find that for every y in the range there is only one x corresponding to that.
Hence this curve is not a many to one curve. It is not linear because it is not a straight line. It is a function.
Hence only correct option is
a) The curve is a one to one function.

How does f(x) = 9x change over the interval from x = 4 to x = 5?
Answer: A
put x = 3 into f(x)=6x and you get f(x) = 18
Put x = 4 into f(x) and you get f(x) = 24
Subtract those two. 24 - 18 = 6
Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.
Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,
6(x+1) = 6x + 6.
+6, it increases.
Answer:C: f(x) increases by factor of 9

jack rolled a die 3 times and got 2 each time. What is the probability he will get 2 on the next roll?
if the die has six sides, the probability that he will roll 2 again is 1/6 since there’s only one 2 out of the six sides
The probability jack will get 2 on the next roll is 1/6.
What is probability?It is the ratio that determines how likely a certain event can occur within a set of possible events.
The probability that jack might roll a 2 can be shown below:The given dice has 6 sides.
The number 2 occurs only on one side of a die.
Therefore, if he were to roll the dice one more time, the probability that he would get 2 can be given by 1/6.
Therefore, the probability that jack will get 2 on the next roll is 1/6.

explain what opposites are and give examples of real world situations
Answer:
Opposites in the numbers world refer to numbers that have the same absolute value, but one is negative, while the other is positive.
For a real world example, consider if you have your friend 5 dollars. The amount you have in the transaction is the opposite of the amount he has in the transaction.
The opposite of a number X is that number that when added to X produces zero. The opposite of X is denoted with −X.
The opposite of a number has the same absolute value as the number but an opposite sign. For example, the opposite of 1 is equal to −1 because 1 + (−1) = 0.
The opposite of zero is zero. This is the only number whose opposite is equal to itself. So zero is the neutral element with regard to addition.
In turn, the opposite of a complex number corresponds to a rotation of 180°.

Answer:
Choose the best estimate for the capacity of a bath tub
A. 5 ml
B. 500 ml
C. 50 cl
D. 500 L
Step-by-step explanation:
The best estimate for the capacity of a bathtub is 500 Liters (500L) as it provides a measure that is comparably similar to the actual volume of a bathtub.
Explanation:The best estimate for the capacity of a bathtub would be 500 Liters (500L). This is because the capacity of a bathtub is usually much larger than a litre. Option A and B provide measurements in millilitres, which are much smaller units (a liter is 1,000 millilitres), and thus would not be sufficient to measure a bathtub's capacity. Option C is calling for centilitres, where 1 centilitre is equivalent to 10 millilitres, still way smaller than a bathtub's capacity. Hence, 500L (500 Litres) is the most reasonable estimation for the capacity of a bathtub.
