Answer:
18/root(14)
Step-by-step explanation:
x=54
y=126
x/root(y)
54/root(126)
54/root(3x3x14)
54/3(root(14))
18/root(14)
<span>x = Joe's age and </span><span>y = James's age
</span><span>Joe is 10 years older than James - equation - x = y + 10
</span><span>In 8 years twice Joe's age will equal three times James's age - equation -
2(x+8) = 3(y+8)
</span>
<span>2(x+8) = 3(y+8) </span>
<span>2(y + 10 +8) = 3(y+8) { substitute y + 10 for x </span>
<span>2(y + 18) = 3(y + 8) </span>
<span>2y + 36 = 3y + 24 </span>
<span>12 = y </span>
<span>Joe is 22 and James is 12.</span>
The difference quotient is just the slope form, in a variation
so that should be (f(x+h)-f(x))/h as x approaches 0
the 2nd option is the differnce quotient, but with the negative distributed
the 3rd option is really f(x)-f(5) because f(5)=61 and that is valid
4th option is wrong because it is (f(x+h)+f(x))/h instead of (f(x+h)-f(x))/h
answer is 4th option
The slope is 1 because there is one x
3W = 384 is the equation and W = 32
