C) The 2 triangles are similar , then we can write:

5x/45 = 20/36 . Cross multiplication:

5x*36 = 45*20
180x = 900   and x = 900/180 , x = 5 (and 5x = 25)

d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:

8x = 60 and x = 60/8 , x = 7.5

Answer:

8w : 3.8974342 ≈ 3.9 or 4 (hope it help)

Step-by-step explanation:

1w : 2

2w : 2 + 10% = 2.2

3w : 2.2 + 10% = 2.42

4w : 2.42 + 10% = 2.662

5w : 2.662 + 10% = 2.9282

6w : 2.9282 + 10% = 3.22102

7w : 3.22102 + 10% = 3.543122

8w : 3.543122 + 10% = 3.8974342

3.8974342 ≈ 3.9 or 4

Jayce is a taxi driver.
REY [17]

Answer:

Jayce's fee (in dollars) for 10th drive on a certain day is K.

Step-by-step explanation:

It is given that M(n) models Jayce's fee (in dollars) for nth drive on a certain day.

We need to find the meaning of M(10)=K.

On comparing M(n) and M(10), we get the value of n is 10.

Since M(n) represents the Jayce's fee (in dollars) for nth drive on a certain day, therefore, M(10) represents the Jayce's fee (in dollars) for 10th drive on a certain day.

M(10)=K

It means Jayce's fee (in dollars) for 10th drive on a certain day is K.

What is the vertex of the graph of g(x)=|x-3|-3
Sedbober [7]

Answer:

(3, -3)

Step-by-step explanation:

The vertex of the most general absolute value function is y = |x|, whose vertex is at (0, 0).   Focusing on the " |x - 3| " tells us that the graph of y = |x| is moved 3 units to the right.  Next, focusing on the " -3 " as it tells us that the resulting graph is shifted 3 units down.  Thus, the vertex of g(x)=|x-3|-3 is at (3, -3).

Find the x- and y- intercepts of <br> y = |x+1| -3 <br><br> Someone help me please
zepelin [54]

Answer:

x-intercepts: (-4,0) and (-2,0) y-intercepts: (0,-2)

Step-by-step explanation:

<u>x-intercept</u>:

y = |x+1| - 3

0 = |x+1| - 3

3 = |x+1|

The numbers -4 and 2 are the x-intercepts because if you add -4 and 1, you get the absolute value of -3, which is 3. If you add 2 and 1, you get the absolute value of 3, which is 3.

<u>y-intercept</u>:

y = |x+1| - 3

y = |0+1| - 3

y = |1| - 3

y = 1 - 3

y = -2
