we have

f(x)=-(x+3)^{2}+7

we know that

The function is a vertical parabola open downward

The vertex is the point (-3,7)

The vertex is a maximum

The range is the interval-----------> (-∞,7]

That means

All real numbers less than or equal to 7

therefore

<u>the answer is the option</u>

All real numbers less than or equal to 7

What’s is the value of n? HELP ASAP PLEASE
earnstyle [38]

Answer:

The answer should be 69°

Step-by-step explanation:

Each line is being cut by a transversal, that means that the degree on the other side of it, added with the given degree will add up to 180°

1. On the right, you need to find the interior angle where 160° is outside so you subtract 180° from 160° to find the angle inside. That gives you 20°

2. On the top left you have 131° so 180°-131°=49°

Next you add the angles you have and then subtract it from 180 to get the interior angle with n° outside.

3. 20°+49°=69°

4. 180°-69°=111°

Then you do the same thing as the beginning which would be n°+111°=180°

5. n°+111°=180°, that means n=69°

Hopefully that clears it up for you :)
