Answer:

BE = 39/5 or 7.8

Step-by-step explanation:

As <ABC = <DBE trigonometric function is angle BAC and angle BED

so sin (<ABC) = sin(<DBE) and AC and BC , BD and BE

so AC/AB = DE/BE = 13/BE = 5/3

So now we cross multiply

BE = 13 × 3 over 5

13 × 3 = 39

and over 5 means

39/5 = 7.8

Given f(x) = 2x - 2/4 the quantity of 2x minus 2 divided by 4, solve for f−1(3).
olga_2 [115]

The answer is that f-1(3) = 7.

In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.

f(x) = (2x - 2)/4 ----> Switch x and f(x)

x = (2f(x) - 2)/4 -----> Multiply both sides by 4

4x = 2f(x) - 2 ----0-> Add 2 to both sides

4x + 2 = 2f(x) ------> Divide both sides by 2

f-1(x) = (4x + 2)/2

Now that we have the inverse function, we can put in 3 and find the answer.

f-1(x) = (4x + 2)/2

f-1(3) = (4(3) + 2)/2

f-1(3) = (12 + 2)/2

f-1(3) = (14)/2

f-1(3) = 7

Please help me! Answer ASAP!
MaRussiya [10]
This would be the Transitive Property of Congruence.

This property of congruence states that if two angles/segments/polygons are both congruent to something else, then they are congruent to each other.

Hope this helps! :)

Write the point-slope form of each graph. Use the red point to write your equation. State the point and slope.
Vinil7 [7]
Answer:

First Graph:

Slope = - 4/5

Point-Slope Form: y - 3 = - 4/5 (x + 2)

Point: (-2, 3)

Second graph:

Slope = 4

Point-Slope Form: y + 6 = 4 (x + 1)

Point: (-1, -6)

Step-by-step explanation:

First graph has two points: (-2, 3) & (8, -5)

Use the two points to find the slope using the Slope-Formula

Slope-Formula: y2 - y1/x2 - x1

m = slope

m = - 5 - 3/8 - - 2

m = - 8/10

m = - 4/5

The slope of the line will be - 4/5

Now for Point-Slope Form, we’ll need to use the two points with the slope to identify the Point-Slope Form of the graph

Two points: (-2, 3) & (8, -5)

Slope: - 4/5

Point-Slope Formula: y - y1 = m (x - x1)

Point-Slope Form: y - 3 = - 4/5 (x + 2)

The point will be: (-2, 3)
