The equation we have right now is basically y = 1/2x + 3. We can switch the x and y variables. Our new equation is: x = 1/2y + 3. Next, we solve for y.

Firstly, we subtract 3 from both sides. This gives us x - 3 = 1/2y. Next, we multiply both sides by 2 to isolate y. This gives us 2(x - 3) = 1/2y. Then, we have 2x - 6 = y.

The answer is f(x) = 2x - 6

A regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. The polygon area can be expr

Marat540 [252]

Answer:

Option (D)

Step-by-step explanation:

Formula to get the area of a regular polygon in a circle will be,

Area = $n[\frac{1}{2}\times (\text{Base})\times (\text{Height})]$

= $n[\frac{1}{2}\times (\text{s})\times (\text{h})]$

Here 'n' is the number of sides.

If n increases, h approaches r so that 'rh' approaches r².

In other words, if the number of sides of the polygon gets increased, area of the polygon approaches the area of the circle.

Therefore, Option (4) will be the answer.

If \\(z_1=3+2i\\) and \\(z_2=4+3i\\) and are complex numbers, find \\(z_1z_2\\)

Dmitry_Shevchenko [17]

$z_1z_2=(3+2i)(4+3i)=3\cdot4+2i\cdot4+3\cdot3i+2i\cdot3i$

$z_1z_2=12+8i+9i+6i^2$

$i^2=-1$ , so

$z_1z_2=12+8i+9i-6=\boxed{6+17i}$

Write the equation for the line that passes through the coordinates (2,7) and (0, 1) in slope-intercept form

Bumek [7]

Answer:

y = 3x + 1

Step-by-step explanation:

y2 - y1 / x2 - x1

1 - 7 / 0 -2

-6 / -2

= 3

y = 3x + b

1 = 3(0) + b

1 = 0 + b

1 = b

y = 3x + 1
