The GCF of 16 and 28 is 4.
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:
See the picture attached
Step-by-step explanation:
- The function means that the variable "y" (dependent variable) depends on x(inependent variable), in the following way: .
- When , , when , then .
- The intercept of the function (the value that makes y=0) will be for x=1, and the slope (which is the coefficient that join x, is (-1). Using this information, you can obtain the graph for this function.
G (x) = -11/4 ...
that's your answer
This problem is very easy when you follow the pemdas rule.
As always, you do multiplications before additions and subtractions, so, you do 9x5 and 7x8 first, then, you can add them together.
<span>9×5+101+7×8=?
(9x5)+101+(7x8)=?
45+101+56=?
= 202</span>
