The triangles are similar. Find the value of the variable.

Vitek1552 [10]

Answer:

y = 27

Step-by-step explanation:

The given are two similar triangles.

We can use the following equation to find the variables:

$\frac{y-3}{32} = \frac{18}{24}$

Cross multiply fractions

32*18 = 24(y-3)

576 = 24y - 72

add 72 to both sides

648 = 24y

divide both sides by 24

27 = y

Find the slope of the line (4,5),(-3,-1)

koban [17]

Step-by-step explanation:

${ \rm{slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }} \\$

• y2 → -1

• y1 → 5

• x1 → 4

• x2 → -3

${ \tt{slope = \frac{ - 1 - 5}{ - 3 - 4} }} \\ \\ { \tt{slope = \frac{ - 6}{ - 7} }} \\ \\ { \boxed{ \tt{ \: slope = \frac{6}{7} }}}$
