Directions: Find each value or measure. Assume that segments that appear to be tangent are tangent ​
SOVA2 [1]

Answer:

x = 7, x = 5

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord.

(1)

27x = 9 × 21 = 189 ( divide both sides by 27 )

x = 7

(2)

12(3x - 5) = 120 ( divide both sides by 12 )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

If D-M-G, DM=2x , MG= x-2 , and DG= 7 , find x
Dmitrij [34]

Step-by-step explanation:

DG is the total measurement of the line. M is a point inbetween D & G

2x + x - 2 = 7

Simplify. Combine likke terms

(2x + x) - 2 = 7

3x - 2 = 7

Isolate the x. First, add 2 to both sides

3x - 2 (+2) = 7 (+2)

3x = 9

Isolate the x. Divide 3 from both sides

(3x)/3 = (9)/3

x = 9/3

x = 3

3 is your answer for x

Can any one give me a fast answer please I need help
icang [17]

Answer:

C = n + 2

Step-by-step explanation:

Well looking at the line on the graph we can see that the y intercept is 2 because the y intercept is the point in the line that touches the y axis.

And the slope is how fat away each points are from each other on a line so we can find the slope by using two points on the line, we can use (1,3) and (2,4).

So we set up the formula like this \frac{y^2-y^1}{x^2-x^1}.

And now we gotta plug in the numbers and solve so the answer is 4-3 = 1 and 2-1 = 1 so the slope is 1.

And we can’t write that as just n.

So the answer is C = n + 2.

For proof look at the image below.
