Answer:y = 15

Step-by-step explanation:

<u>Concept:</u>

Here, we need to know the idea of similar triangles.

Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

<em>Set up the proportion between the sides</em>

Small / Big = Small / big

10 / 22 = y / 33

<em>Cross-multiply to simplify the proportion</em>

22 · y = 33 × 10

22y = 330

<em>Divide 22 on both sides</em>

22y / 22 = 330 / 22

y = 15

Hope this helps!! :)

Simplify the following expression. 3 2/5x3(-7/5)
Studentka2010 [4]

The simplified expression of 32/5 x 3(-7/5) is  -672/25

<h3>How to simplify the expression?</h3>

The mathematical expression is given as:

32/5 x 3(-7/5)

Evaluate the product of 3 and -7/5

32/5 x 3(-7/5) =  32/5 x -21/5

Evaluate the product of 32 and -21

32/5 x 3(-7/5) =  672/5 x -1/5

Evaluate the product of 5 and 5

32/5 x 3(-7/5) =  672/25 x -1

So, we have:

32/5 x 3(-7/5) =  -672/25

Hence, the simplified expression of 32/5 x 3(-7/5) is  -672/25

What is the equation of the line expressed in slope-intercept form?
Alisiya [41]
(x,y)
x=how far to the right
y=how far up
ok so
y=mx+b
m=slope
b=y intercept or where the line intercept the y axis

it looks like the line intercept the y axis at 2 high so
y=mx+2
we look at our options and we see that there is only 1 equation that has y=mx+2
that is B
B is the answer
