Answer:

y = 2x-4

all the equations are the same as the slope-intercept form is the same for all the equations

Step-by-step explanation:

slope-intercept form:

y = mx + b

2x-3 = y+1

<h3>i) move y to the left-hand side and change its sign</h3>

-y+2x-3 = 1

<h3>ii) move 2x-3 to the right-hand side and change its sign</h3>

-y = 1-2x+3

<h3>iii) add the numbers</h3>

-y = (1+3)-2x

-y = 4-2x

<h3>iv) change the signs on both sides of the equation </h3>

y = -4+2x

<h3>v) use the commutative property to reorder the terms</h3>

( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )

y = 2x-4

What is the value of a for the following circle in general form?<br> x2 + y² + ax + by+c=0
motikmotik

Answer:

Step-by-step explanation:

x2+y2+ax+by+c=0

Step 1: Add -by to both sides.

ax+by+x2+y2+c+−by=0+−by

ax+x2+y2+c=−by

Step 2: Add -x^2 to both sides.

ax+x2+y2+c+−x2=−by+−x2

ax+y2+c=−bax+y2+c+−y2=−by−x2+−y2

ax+c=−by−x2−y2

Step 4: Add -c to both sides.

ax+c+−c=−by−x2−y2+−c

ax=−by−x2−y2−c

Step 5: Divide both sides by x.

ax

x

=

−by−x2−y2−c

x

a=

−by−x2−y2−c

x

y−x2

Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. An equation y = m x + b represents Dave’s we
vovangra [49]

Answer:

y = 0.1x+200

Step-by-step explanation:

First, let's establish that:

x is independent

y is dependent

Basically, the value of y will depend on what x is.

The problem states that the slope of the line is Dave's comission, so since he makes 10% of comission, we can make the slope as 0.1x (mx)

The problem also states that the y intercept (b) is Dave's base salary, and earlier in the problem it states that his base salary is $200 a week. Therefore, b=200

now, the equation is:

y=0.1x+200

Hope this helps!
