Which is the equation in slope-intercept form for the line that passes through (-2, 15) and is perpendicular to 2x + 3y = 4?
Ilya [14]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 3y = 4 into this form

Subtract 2x from both sides

3y = - 2x + 4 ( divide all terms by 3 )

y = - \frac{2}{3} x + \frac{4}{3} ← in slope- intercept form

with slope m = - \frac{2}{3}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{3} } = \frac{3}{2}, hence

y = \frac{3}{2} x + c ← is the partial equation of the perpendicular line

To find c substitute (- 2, 15) into the partial equation

15 = - 3 + c ⇒ c = 15 + 3 = 18

y = \frac{3}{2} x + 18 → B

6 to power 8 / 6 to power of 6 equals what does the slash mean. How do I calculate
artcher [175]

Step-by-step explanation:

From your problem statement, I believe the equation will look like this:

\frac{6^{8}}{6^{6}}

The slash means "divided by" -- you should use division to solve this equation.

For division involving exponents with the same base, you can use the following rule:

\frac{A^{x}}{A^{y}} = A^{x - y}

Subtituting 6 for A, 8 for x and 6 for y, we get the following:

\frac{6^{8}}{6^{6}} =6^{8 - 6} = 6^{2} = 36

What is the inverse function of d(x) = 2x - 4?
zysi [14]

Answer:

d^{-1}(x) = \frac{x+4}{2}

Step-by-step explanation:

let d(x) = y and rearrange making x the subject, that is

2x - 4 = y ( add 4 to both sides )

2x = y + 4 ( divide both sides by 2 )

x = \frac{y+4}{2}

Change y back into terms of x, so

d^{-1}(x ) = \frac{x+4}{2}

This circle is centered at the origin, and the length of its radius is 2. What iS
Igoryamba

Answer:

Step-by-step explanation:

If the center of the circle is at the origin, the general formula for the circle is

x^2 + y^2 = r^2.

Since r  = 2 units in this particular problem, the equation of the circle is:

x^2 + y^2 = 2^2,  or  x^2 + y^2 = 4
