Hello!
To find the vertex of f(x), we can simplify this function into standard form.
f(x) = (x - 8)(x - 2)
f(x) = x² + -10x + 16
With the equation in standard form, we use the formula: x = -b/2a. Then, we substitute the value of x into the equation to solve for the y-value.
x = -(-10) / 2(1)
x = 10 / 2
x = 5
Then, we substitute x = 5 into the original equation.
f(x) = (5 - 8)(5 - 2)
f(x) = -3(3)
f(x) = -9
Therefore, the vertex of f(x) is (5, -9).
Answer:
(y+3) (x^2+3)
Step-by-step explanation:
x^2y + 3x^2 + 3y + 9
I will factor by grouping
Taking the first two terms I can factor out x^2
Taking the last two terms I can factor out 3
x^2y + 3x^2 + 3y + 9
x^2(y+3) + 3(y+3)
Now I can factor out (y+3)
(y+3) (x^2+3)
Since(x^2+3) and (y+3) cannot be factored , this is completely factored
Answer: Ithink it’s 3, 5, 9
The answer is $2,062.50
$1,100=1/3 + 1/5 of his money
therefore 1,100 = 5/15 + 3/15 = 8/15
I want to know what 15/15 is equal to
therefore I must first determine 1/15
1,100/8 = 137 1/2 = 1/15
The entire sum of money is 15/15 so it is 137 1/2 * 15 = $2,062.50
Yes, -6.8 is a rational number because we can express it as a fraction.
All integers are rational, but rational numbers are not integers.
Integers are positive, negative numbers and zero.
Hope it helps!
Good luck! :)
