Step-by-step explanation:

the point-slope form is

y - y1 = m(x - x1)

where (x1, y1) is a point on the line.

m is the slope of the line, which is always (in any form) the factor of x.

the parallel line has -2/8 as factor of x, which is therefore also the slope of our new line (after all, it has to be parallel, so it must have the same slope).

so, we have

y + 5 = -2/8 × (x - 4)

which can be simplified, of course, to

y + 5 = -1/4 × (x - 4)

The measures of the angles of a triangle are shown in the figure. solve for x

yuradex [85]

Answer:

solution,

x+41+59=180⁰ ( the sum of total angle of triangle is 180⁰)

or, x+ 100=180

or, X=180-100

so , X=80

Step-by-step explanation:

let us check

59+41+80=180

Find the quotient 4.2 ÷7

Nookie1986 [14]

Find the quotient 4.2 ÷7=> 4.2 is our dividend which is a decimal number. 4 as the whole number and 2 is the decimal number.=> 7 is our divisor that will be use to divide with 4.3Let's now start solving:=> 4.2 / 7 = 0.6<span>Thus the quotient of the given data is 0.6 which is also a decimal number same as the divisor.</span>

if r does not equal 0, which of the following polar coordinate pairs represents the same point as the point with polar coordinat

konstantin123 [22]

Answer:

First option

(r, θ - 2π)

Step-by-step explanation:

Polar coordinates are a representation in terms of a given longitude r, and an orientation given by an angle. (Please see attached image)

Since the polar coordinate is cyclic (The values from the angle go from 0 to 2π and then go through the same values again) if we add or subtract 2π, from any value we find ourselves in the same initial position

So, any point can be represented by

(r, θ ± 2π)
