What is the sign of 3 x y 3xy3, x, y when x &gt; 0 x&gt;0x, is greater than, 0 and y &lt; 0 y&lt;0
Colt1911 [192]

Answer:

The sign is negative

Step-by-step explanation:

Given

Expression = 3xy

x > 0

y

Required

Determine the sign

The expression can be split into 3 factors

(3) (x) (y)

If x > 0 then x is positive and If y < 0 then y is negative

So, the expression becomes:

(+3) (+x) (-y)

<em />

Leave only signs

(+) (+) (-)

+ * + = -

So, we have:

(+*+) (-)

(+) (-)

+ * - = -

So, we have:

(+) (-) = -

<em>Hence, the sign of the expression is negative</em>

<em></em>

Take for instance;

x = 2

y = -4

The expression would be:

3 *2 * - 4 =-24 -- negative

What is the graph of y=-(x-2)^3-5
natulia [17]
When x=0,
y=-(0-2)^3-5
y=3

When y=0,
(x-2)^3=5
x-2= +/- 5^1/3
x= +/- 5^1/3 +2
x= 3.70997 or x=0.29002

To find the turning point at y, substitute the information that you have found above.

y=-(3.70997-2)^3-5
y=-9.99994

Find the mid-point next as mid-point is also the turning point.

(3.70997+0.29002)÷2=1.999995

Hence, Turning point is (1.999995, 9.99994)

Plot a graph using turning point, y value and the 2-x values.
