1/4 is adding to the 1 so it would be farther down on a number line because you are subtracting more

What is the equation of the graphed line written in standard form? 2x – y = –4 2x – y = 4 y = 2x – 4 y equals StartFraction one-

svp [43]

Answer:

The answer is "2x-y=4"

Step-by-step explanation:

Given:

$2x-y=-4\\2x-y=4\\y=2x-4\\y=\frac{1}{2}(x-4)\\$

The Formula of Slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

by replacing the (2,0) and (0,-4) coordinates in the above formula:

$\to m= \frac{-4-0}{0-2}\\\\ \to m= \frac{-4}{-2}\\\\ \to m= \frac{4}{2}\\\\ \to m= 2\\\\$

if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.

Equation of the line:

$\to y=mx+c$

apply m and c value in the above equation:

$\to y=2x-4\\$

Subtract by 2x on both sides of the equation we get:

$\to y-2x= 2x-4-2x\\\\\to y-2x=-4\\\\\boxed{\boxed{2x-y=4}}\\\\$

Simplify the expression.<br> -5+i /2i

Andrei [34K]

Answer:

$\frac{1+5i}{2}$

Step-by-step explanation:

We know i×i=i^2 which has value of -1.

We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).

Also multiplying by i/i does not change the value of the fraction because i/i=1.

Numerator × i gives (-5+i)i=-5i+i^2=-5i-1

=-1-5i.

Denominator × i gives (2i)i=2i^2=-2.

So the simplified version of this fraction given is:

$\frac{-1-5i}{-2}=\frac{1+5i}{2}$

The last simplification come from me multiplying fraction by -1/-1.

How are integers and their opposites related? give an example with numbers.

alukav5142 [94]

Answer:

Integers are the set of whole numbers and their opposites. Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign. an example with numbers is 17positive and 17 negative both are 17 (clicks/jumps/etcetera) away from 0. There is no 0 positive or negative.
