Which value is the solution of

Mathematics
1 answer:
pentagon [3]2 years ago
5 0

Answer:

A

Step-by-step explanation:

\sqrt[3]{3x} + 7 = 4 ( subtract 7 from both sides )

\sqrt[3]{3x} = - 3 ( cube both sides to clear the radical )

3x = (- 3)³ = - 27 ( divide both sides by 3 )

x = - 9

Find the midpoint of segment JT when the coordinates are J(-3,18) and T(7,-10). Show all work
nignag [31]
Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2  ).
In this case:
J(-3,18)
T(7,-10)

The midpoint will be:
( (-3+7)/2  ,  (18-10)/2 )=(4/2 , 8/2)=(2, 4).

Answer: the midpoint of segment JT is (2,4)

Sketch the points (0,5,2),(4,0,-1),(2,4,6) and(1,-1,2) o a single set of coordinate axes?
nordsb [41]

Explanation:

As points have three coordinates i.e. x, y and z hence the sketch of the given four points is drawn in 3D shape and for that picture is attached here with this answer.

Points are given in the format as below

(value of x-coordinate , value of y-coordinate , value of z-coordinate)

In the attachment:

Point A = (0,5,2) (in blue color)

Point B = (4,0,-1) (in purple color)

Point C = (2,4,6) (in orange color)

Point D = (1,-1,2) (in black color)

To the nearest​ dollar, the average tuition at a public four−year college was $3088 in 1997 and $3292 in 2000. ​Find, to the nea
Delicious77 [7]

the fees in 1997 was $3088

fees in 2000 was $3292

average rate of increase= (3292-3088)/(2000-1997) = 204/3=68

so average rate of increase is $68 per year

Please help me! I'm spending 50 points on this question and my last two questions never even got answered!
Verdich [7]

Answer:

C.

Step-by-step explanation:

Domain is only affected if certain values can make the result something that either doesn't make sense or is an error. In your situation, it wants you to find the domain of f/g, which is a fraction. The only rule we have for fractions regarding domain is that we simply can't divide by zero, to find the domain for any fraction with variables in the denominator, what I do is take the denominator, set it equal to 0, and solve for x.

So, if we're taking f/g, we have:

\frac{3x^2 + x^4 + 2}{4x - 3}

4x - 3 makes up our denominator, the bottom part of the fraction. So

4x - 3 = 0

4x = 3

x = 3/4

So the denominator is equal to zero when x is equal to 3/4. This would produce an error in any calculator because you can't divide by zero. The domain here is all real numbers except for 3/4.

(For future problems, the only thing to look out for is if your numerator, the top part of the fraction, factors into something that cancels with the bottom. In that case, it wouldn't affect domain because you aren't actually dividing by anything. For example:

\frac{x^2 - 4}{x-2}

If we factor the top, we see that x^2 - 4 = (x - 2)(x + 2). In this case, we have (x - 2) in both the top and bottom of the fraction, so it cancels out, and from there nothing else is restricting our domain. It would be all real numbers in a case like that.)

A) 2-x,when x=5
MrRissso [65]

Answer:

a) 2-5 = -3

b) 3(4) + 2(4) = 20

c) (3(5)+2)(5-4) = 17

Step-by-step explanation:

Substitute the variables for their values and then solve from there. Hopefully this helps, I don't know if I answered your question fully.
