Answers

Answer: x = 24

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Remove parentheses.

12 (2 − 2) + 32 = [tex]x[/tex] + 6 + 2

Step 2: Simplify 2 − 2 to 0.

12 × 0 + 32 = [tex]x[/tex]  + 6 + 2

Step 3: Simplify 12 × 0 to 0.

0 + 32 = [tex]x[/tex] +  6 + 2

Step 4: Simplify 0 + 32 to 32.

32 = [tex]x[/tex] + 6 + 2

Step 5: [tex]x[/tex] + 6 + 2 to [tex]x[/tex] + 8.

32 = [tex]x[/tex] + 8

Step 6: Subtract 8 from both sides.

32 − 8 = [tex]x[/tex]

Step 7: Simplify 32 − 8 to 24.

24 = [tex]x[/tex]

Step 8: Switch sides.

[tex]x[/tex] = 24

a cylinder has a volume of 78 cm what is the volume of a cone with the same radius and height

Answers

Answer:

Volume of cylinder V= bh= 78 cm^3, where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3

Thanks!

Mark me brainliest!

Answer:

Volume (cone) = 26 cm³

Step-by-step explanation:

Given :-

Volume (cylinder) = 78 cm³

To Find :-

Volume (cone) with same height and radius

Solving :-

Find the equation for the volume of the cylinder.

πr²h = 78 cm³

But we know the volume of a cone is 1/3 of the volume of a cylinder.

=> Volume (cone) = 1/3 x 78

=> Volume (cone) = 26 cm³

The given function is f (x) = 5x + 1. The value of the function at x equal to 0 will be calculated as below:-

f (x) = 5x + 1

f (0) = 5 x 0 + 1

f (0) =  0 + 1

f (0) = 1

Step-by-step explanation:

The area = 252 in²

One side = 14 in

The other side = x

Step-by-step explanation:

First let know what is a quadratic functions(s):

A function is called Quadratic if it consist of  only one variable, maximum of three terms, and highest degree of the variable  in that Polynomial is 2.

Now let's go through the answer choices:

[A]  

y *(y+4) - y =6

y² + 4 y - y -6=0

y²+3 y -6=0

Thus, This is Quadratic Function.

[B]

3 x +2 + 6 x -1=0

9 x-1=0

Thus, This is not Quadratic Function

[C]

4 b*(b)=0

4 b²=0

Thus, This is Quadratic Function.

[D]

3 a- 7 =2 * (7 a-3)

3 a - 7=14 a - 6

3 a - 14 a = 7 -6

Thus, This is not a Quadratic Function.

Hence, [A] and [C] are quadratic functions.

A function is a set of ordered pairs in which no two different ordered pairs have the same “x -coordinate”. An equation that produces such a set of ordered pairs defines a function

Algebraically, an ordered pair is a solution to a system of two linear inequalities if and only if it __________.
A.
makes both the top and bottom inequalities false
B.
makes the top inequality true and the bottom inequality false
C.
makes the top inequality false and the bottom inequality true
D.
makes both the top and bottom inequalities true

Answers

Answer:

D.  Makes both the top and bottom inequalities true

Step-by-step explanation:

System of linear inequalities

Consider these two inequalities:

2x+3y > 20

3x-2y > 5

The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because

2*3+3*5=21 and it's effectively greater than 20.

But that pair makes the second inequality false, since

3*3-2*5=-1 is not greater than 5.

Thus, the pair (3,5) is not part of the solution.

If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.

Thus, the correct answer to the question is

D.  Makes both the top and bottom inequalities true
