The region describes a rectangle. F(x,y) is optimized at the intersecting points around the rectangle.
You can try plugging in (-3,-5) , (-3,4), (4,4) , (4,-5) and see which one gives you the largest value.
The max value of f(x,y) is at point (4,-5)
---> 4(4) - 7(-5) = 16 + 35 = 51
Answer:
x=32
Step-by-step explanation:
Multiply both sides by 4.
(x/4)*(4) = (8)*(4)
Answer:
Both 4x^2 and 64 are perfect squares
Step-by-step explanation:
If you are looking for the difference of squares, the two terms both have to be squares. We know that 64 is a square because it is 8 x 8. Also, we can say 4x^2 is a square because it can also be written as (2x)^2. We are basically looking for an option that tells us that they are square. This is option 1.
The second option is invalid because being an even number does not mean the number is a square.
The third option does not help the case much either. Just because there is a common perfect square factor, does not mean the numbers themselves are perfects squares.
Answer:
30%
for example for 100 the 30% of 100 is 30
but the 1/4 of 100 is 25
Step-by-step explanation:
MARK ME BRAINLIEST PLS I NEED IT
I'm assuming you mean, what equals x.
Well, if 7x = 94, we know that 7 x's = 94.
Therefore, is you divide 94 by 7, you will get your answer.
