Fraction form: x=7/12
Steps:
64^4x-3
2^6(4x-3)=2^-4
6(4x-3)=-4
4x-3=-2/3
4x=7/3
X=7/12
Suppose you had f=6, g=2, h=3 and you were asked to find
f - g - h
You would do it by substituting the given values for the letters to get
6 - 2 - 3
And this can be simplified to
1
_____
The question at hand is basically the same. You are given values of f(x), g(x), h(x) and asked to find their signed sum.
f(x) - g(x) - h(x)
= (3x+5) - (4x²-2) - (x²-3x+1) . . . . substitute the given values
= 3x + 5 - 4x² + 2 - x² + 3x - 1 . . . use the distributive property to eliminate parentheses. A minus sign in front changes the sign of every term inside parentheses.
= x²(-4-1) +x(3+3) +(5+2-1)
= -5x² + 6x + 6 . . . . . . collect terms . . . . matches the first choice
Answer:
1/3 of the original
Step-by-step explanation:
As an an object is scaled up with the same proportions, one might think ts strength to weight ratio scales up with it. However, since the object as it scales greater in size also increases in weight, the strength to weight ratio actually decreases. If the elephant is scaled up 3 times, then its strength to weight ratio is divided by the same amount and is 1/3 the original or 1/3 as much.
