Answer: x=-2+2 sqrt 6 divided by 5
Hoor this helps
Step-by-step explanation:
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.
Answer:
32 is 40% of 80.
Step-by-step explanation:
80×4÷10=320÷10=32
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
