Answer:
x = 19
Step-by-step explanation:
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60 Use dist property
Subtract 3x from both sides
-3 = 3x - 60
Add 60 to both sides
57 = 3x
Divide both sides by 3
19 = x
Answer:
Ef=52
Step-by-step explanation:
By the mids segment theorem if a line sgement has endpoints on the midpoints of 2 sides of a triangle then it is half the size of the third side.
That means
2(4x+8)=9x-5
8x+16=9x+5
11=x
Then plug it back in to EF
4(11)+8
44+8
52
If you are adding the same number in a sequence, then it is arithmetic. If you are multiplying by the same number, it is geometric. Since here you are adding the same number (4), it means that the series <span>1 + 5 + 9 + 13 + 17 + . . </span><span>is arithmetic. </span>
Answer:
Step-by-step explanation:
The standard form for the equation of a circle is

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5). We will use these to solve for r-squared, then plug back in what we need to write the equation.
which simplifies to
and
so

Filling in the equation:
