Answer:
A
Step-by-step explanation:
Since we're dealing with perpendicular lines, we take the recipricol of the m value of the original equation.
So the slope we're dealing with is 1/2.
And the equation we have so far is
y = 1/2x + b
Now we solve for b by plugging in the point (4,2).
2 = 1/2(4) + b
2 = 2 + b
b = 0
So the final equation is
y = 1/2x
<span>g(x) = x^2 + 4x + 3
y-intercept: let x=0. Then y=3. y-intercept is (0,3).
roots: set g(x) = 0 and solve for x. x=-1 and x=-3.
-4
axis of symmetry: find x = -b / (2a), which here is x = ----- = -2

Answer:
<em>10 miles</em>
Step-by-step explanation:
Distance d = v t
v - speed/velocity
t - time
<em>d</em> = 
(8) + 
(12) = 6 + 4 = <em>10 miles</em>
If one of the numbers we multiply (factors) has zeros at the end, and the other isn't a fraction: all those zeros will stay in the product.
But there might be additional zeros if the other numbers in the factors (the numbers which aren't 0) mupliply to "end" in zero and this is the case here:
8*5=40.
so the product will be 40 and the zeros of the 5000:
40 000
the number of zeros in the product will be bigger than the number of zeros in the factors if the non-zero parts of the fractions multiply to a number with 0 at the end.
