End fraction is a lot of math lol but try the 16=6 x
Well 4/4 is equivalent to 1 so do 4/4+3/4
your answer would be 7/4
Answer:
b
Step-by-step explanation:
1. the function will approach negative infinity as x approaches neg/pos infinity because -x^4 (highest power) will result in both ends pointing down. this rules out a and d.
2. skip the Maxima/minima part
3. to test for zeroes, list all possible zeroes using rational zero theorem. then use synthetic division to test out the differing zeroes between b and c.
we find -5 leaves us with remainder of 0, so it is a zero where as -7 leaves us with some remainder that isn't 0, so it is not a zero.
the only option with the function approaching negative infinity with a zero at -5 is b
A mathematical equation is an expression containing at least one variable and an equals sign with a mathematical expression on each side of it.
Let's take as x and y the age of the man and of his son
We will do a system, so we can satisfy all the request:
1. sum of ages = 2 (difference)
2. product = 675
semplify the first equation
x + y = 2x -2y
now let's choose one of the incognite (x) and we solve for it
x - 2x = - 2y - y
- x = - 3y
x = 3y
Let's substitute this solution in the second equation
note: x = 3y, so in the second equation x * y = 3y * y
Now let's solve the second equation
3y * y = 675
3y² = 675
y² = 675 / 3 =
y² = 225
y = 15
Son's age is 15
Man's age is 15 * 3 = 45 (See the first equation [x = 3y])
