The first step is to change the equations into y format. y= mx + b.
The y- intercept of this graph is at the point (0,2). Since the line is going down, the slope is negative. Therefore it would be: y+2 = -(x-4)
If changed it would be y= -x + 2.

2(4x - 1) + 3(3 - 2x) = 0

LUCKY_DIMON [66]

2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2

How many meters is one centimeter cubed? Also, how many meters cubed are in one liter?

enot [183]

1 m = 100 cm
1 m^3 = 1^6 cm^3

so 1 cm^3 = 10^-6 m^3

and 1 L = 1000 cm^3 = 10^-3 m^3

What binomial do you have to add to the polynomial:

marshall27 [118]

Answer:

a) $-2x^2+5xy$

b) $-3y^2+5xy$

Step-by-step explanation:

Given polynomial : $2x^2+3y^2-5xy+1$

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable x is:

$-2x^2+5xy$

$(2x^2+3y^2-5xy+1)+(-2x^2+5xy)$

$=2x^2+3y^2-5xy+1-2x^2+5xy$

$=2x^2-2x^2+3y^2-5xy+5xy+1$

$=3y^2+1$

Given polynomial : $2x^2+3y^2-5xy+1$

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable y is:

$-3y^2+5xy$

$(2x^2+3y^2-5xy+1)+(-3y^2+5xy)$

$=2x^2+3y^2-5xy+1-3y^2+5xy$

$=2x^2+3y^2-3y^2-5xy+5xy+1$

$=2x^2+1$
