I need to graph -3x+2y=4

1 answer:

5 0

-3x + 2y = 4
2y = 3x + 4
y = 3/2x + 2

so ur slope is 3/2 and ur y int is (0,2)

ur x int can be found by subbing in 0 for y and solving for x
-3x + 2(0) = 4
-3x = 4
x = -4/3...so ur x int is (-4/3,0)

so plot ur x and y intercepts (0,2) and (-4/3,0)....and start at (-4/3,0) and since ur slope is 2, go up 2 spaces and to the right 1 space, then up 2 spaces, and to the right 1 space...keep doing this and u should cross the y axis at (0,2)

8. Is the following statement true or false? Justify your conclusion. If a and b are nonnegative real numbers and a + b =0, then

atroni [7]

Answer:

If $a + b = 0$ then $a = 0$ and $b =0$

a | b | a + b (answer)

0 | 0 | 0

0 | 1 | 1

0 | 2 | 2

1 | 0 | 1

2 | 0 | 2

1 | 1 | 2

2 | 1 | 3

Step-by-step explanation:

Considering the following conditions for the real numbers:

$a\geq 0\\b\geq 0$

Following the rules of these in-equations, it is possible to deduce:

$a + b \geq 0$

Then, if the proposed statement is:

$a + b = 0$

The conditions above shall comply the requirements established, but first, analyzing the statement:

If $a \geq 0$ and $b \geq 0$ then $a + b \geq a$ , $a + b \geq b$ and $a + b \geq 0$ .

If $a = 0$ and b a non negative real number, then $a + b \geq b$ , but because to $a = 0$ , then $a + b = b$ . Due to the commutative property of sums, the same behavior will be presented if $b = 0$ and a a non negative real number.

According to that, if $a + b = 0$ , then $a = 0$ and $b = 0$ .
