Answer:

(8, 20)

Step-by-step explanation:

Let's input each values of the ordered pair given as options to see which one satisfy the equation y = 16 + 0.5x

==>Option 1: (0, 18)

18 = 16 + 0.5(0)

18 = 16 + 0

18 ≠ 0

Option 1 is incorrect.

==>Option 2: (5, 19.5)

19.5 = 16 + 0.5(5)

19.5 = 16 + 2.5

19.5 ≠ 18.5

Incorrect.

==>Option 3: (8, 20)

20 = 16 + 0.5(8)

20 = 16 + 4

20 = 20

CORRECT

==>Option 4: (10, 21.5)

21.5 = 16 + 0.5(10)

21.5 = 16 + 5

21.5 ≠ 21

Incorrect.

The answer is (8, 20)

Answer:

$x=\frac{7}{5}$

$y=-\frac{22}{5}$

Step-by-step explanation:

Given:

The given expressions are.

$6x+y=4$

$x-4y=19$

We need to find x and y values.

Solution:

Equation 1⇒ $6x+y=4$

Equation 2⇒ $x-4y=19$

First solve the equation 1 for y.

$6x+y=4$

$y = 4-6x$ --------(3)

Substitute $y = 4-6x$ in equation 2.

$x-4(4-6x)=19$

Simplify.

$x-(4\times 4 - 4\times 6x)=19$

$x-(16-24x)=19$

$x-16+24x=19$

Add 16 both side of the equation.

$25x-16+16=19+16$

$25x=35$

$x=\frac{35}{25}$

Divide Numerator and denominator by 5.

$x=\frac{7}{5}$

Substitute x value in equation 3 and simplify.

$y=4-6(\frac{7}{5})$

$y=4-\frac{6\times 7}{5}$

$y=4-\frac{42}{5}$

$y=\frac{5\times 4-42}{5}$

$y=\frac{20-42}{5}$

$y=-\frac{22}{5}$ .

Therefore, the value of $x=\frac{7}{5}$ and $y=-\frac{22}{5}$ .

The height of a cylinder is twice the radius of its base.

Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be $2x$ .

Now we will use volume of cylinder formula to our given problem.

$V=\pi r^2h$ , where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

$V=\pi\cdot x^2\cdot 2x$

$V=2x^3\pi$

Therefore, our required volume expression would be $2x^3\pi$ .
