Your multiplying by -4 each time
-1x-4=4
4x-4=-16
-16x-4=64
Perimeter = 26 Explanation: count the sides of the shape then add them all
(2308*10)/100=230.3 so he would have to pay 230 hundos (and 30 singles)
To answer this, you need to know the general form of an absolute value function. the equation for this is f(x<span>) = </span>a|x<span> - </span>h<span>| + </span>k, and in this equation, the vertex is (h, k).
with that information, you can see that your vertex will be (-5, 7). you must take the negative for 5 because the general equation states that your h value is usually subtracted from x. to check your vertex, try plugging it into your general equation:
f(x) = a|x - (-5)| + 7
f(x) = a|x + 5| + 7 ... you see that this matches your given equation. this last part here was just to show why your 5 must be negative; your answer is bolded.
The answer is C that can be the x-intercepts of the parabola
