What’s the question? Maybe then I can help.
Answer:
It can be factorised
Step-by-step explanation:
Given
x²y² + 36 - 4x² - 9y² ( rearranging )
x²y² - 4x² - 9y² + 36 ( factor first/second and third/fourth terms )
= x²(y² - 4) - 9(y² - 4) ← factor out (y² - 4) from each term
= (y² - 4)(x² - 9)
Both factors are a difference of squares and factor in general as
a² - b² = (a - b)(a + b)
Thus
y² - 4
= y² - 2² = (y - 2)(y + 2) , and
x² - 9
= x² - 3² = (x - 3)(x + 3)
Hence
x²y² + 36 - 4x² - 9y² = (y - 2)(y + 2)(x - 3)(x + 3)
Answer:
the number will have the three decimal places is 19.3
Step-by-step explanation:
The computation of the number will have three decimal places is as follows
If we go through the options
We multiplied the larget number given in the options i.e. 19.3
So,
= 84.12 × 19.3
= 1,623.516
This represent that it contains the three decimal places
Therefore the number will have the three decimal places is 19.3
Hence, the same is to be considered
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
-3x-2y=2
step 1
Find the y-intercept
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
-3(0)-2y=2
-2y=2
y=-1
The y-intercept is the point (0,-1)
step 2
Find the x-intercept
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
-3x-2(0)=2
-3x=2
x=-2/3=-0.667
The x-intercept is the point (-0.667,0)
step 3
Find the third point
For x=2
substitute
-3(2)-2y=2
-6-2y=2
-2y=8
y=-4
The third point is (2,-4)
step 4
Plot the points and graph the line
see the attached figure
Note Just two points was enough to draw the line.
PATHOGEN: in biology, a pathogen in the oldest and broadest sense, it is anything that can produce disease. A pathogen can also be referred to as an infectious agent, or a germ.
