Answer:

(1,-3), (2,-2)

Step-by-step explanation:

The graph passes through (3, -1) and (0, -4)

The slope is:

(-4 - (-1))/-3 = -3/-3 = 1

The y-intercept is given: -4

The line is:

y = x - 4

See the graph

The points plotted as well and those on the line are:

(1,-3)
(2,-2)

Hello :
answer : D
because : x=0 and y = 0 satisfait : 4x-3y = 6x+y
4(0) -3(0) = 6(0) +0

Which complex number is a distance of sqrt17 from the origin on the complex plane?

lions [1.4K]

Let z=x+iy be a complex number. The distance from this complex number to the origin is

$\sqrt{(x-0)^2+(y-0)^2}=\sqrt{x^2+y^2}.$

Consider all options:

A. z=2+15i, then $\sqrt{2^2+15^2}=\sqrt{229}.$

B. z=17+i, then $\sqrt{17^2+1^2}=\sqrt{290}.$

C. z=20-3i, then $\sqrt{20^2+(-3)^2}=\sqrt{409}.$

D. z=4-i, then $\sqrt{4^2+(-1)^2}=\sqrt{17}.$

Answer: correct choice is D.

If the probability of an event happening is 86/99, what are the odds against it happening?

Firdavs [7]

P(Event Happening) + P(Event Not Happening) = 1

P(Event Not Happening) = 1 - P(Event Happening)

P(Event Not Happening) = 1 - 86/99

P(Event Not Happening) = 13/99

What is the sum of r+s, when r = –14.1 and s = 18.3?

Basile [38]

$Subtitute\ the\ values\ of\ r=-14.1\\and\ s=18.3\ to\ the\ expression\ r+s:\\\\r+s=-14.1+18.3\\---------\\use\ commutative\ property:a+b=b+a\\\----------\\\\=18.3+(-14.1)=18.3-14.1=\huge\boxed{4.2}$
