Answer:
but theres no graph
Step-by-step explanation:
X² - 16xy + 64y²
= x² - 2*8xy + (8y)²
= (x - 8y)²
The relationship between fractions and decimals is that with a fraction you are dividing whereas a decimal is treated like a number.
i.e. 1/4=0.25
Think of decimals as 100 being the whole or 1 so split 100 into 4 and you get 25 or 0.25
"y varies directly as x" means y = kx
you do not know what k is yet, other than that it is some constant number.
Now plug in the given values, y=12 when x=4, in the equation
12 = 4k
=> k = 3
Now rewrite the equation with the k value you just found
y = 3k
Substitute 18 in place of x
y = 3(18)
y = 54
The way to solve radicals include:
- Determine the prime factors of the number under the root.
- Write the prime factors in groups.
- Simplify any multiplication and exponents.
- Simplify the radical until no further simplification can be done.
<h3>How to illustrate the information?</h3>
It should be noted that your information is incomplete. Therefore, an overview will be given.
When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol.
For example, 3√(8) means to find the cube root of 8
