What is the value of x?

Mathematics
1 answer:
vaieri [72.5K]3 years ago
4 0

Answer:

x=54

Step-by-step explanation:

These angles are vertical angles, which means they are equal

2x+2 = 3x-52

Subtract 2x from each side

2x+2-2x = 3x-52-2x

2 =x-52

Add 52 to each side

2+52 = x-52

54=x

vaieri [72.5K]
A ∪ B is {1, 2, 3, 4, 5, 7}

Set up the union notation of set {1,2,3,4} and {2,5,7}.
{1,2,3,4}∪{2,5,7}

The union of two sets is the set of elements which are in either sets.

I can't get to get this right can you please help me​

Answer:

(-7,4]\text{ or }\{x|-7

Step-by-step explanation:

The domain is the span of x-values covered by the function.

From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.

However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.

Therefore, the domain is, in interval notation:

(-7,4]

We use parentheses on the left because we do not include -7. And we use brackets on the right because we <em>do </em>include the 4.

And in set notation, this is:

\{x|-7

Molly runs each morning once around a circular path in her neighborhood. if the diameter of the path is 1.4 miles, how far does
Lemur [1.5K]
To work out the distance of the path, you need to find out the circumference.
Formula for circumference = pi multiplied by the diameter

So you simply do:
pi multiplied by 1.4 miles

And you should get:
4.39822971503... miles

Simply round the result to an appropriate value (e.g. 3 decimal places).

Answer: 4.398 miles (to 3dp)
Hope the answer helps :)
