Y varies directly as z, y=180, z=10 , find ywhen z=14
FinnZ [79.3K]

<h2>y = 252</h2>

Step-by-step explanation:

To find the value of y when z = 14 we must first find the relationship between them

The statement

y varies directly as z is written as

y = kz

where k is the constant of proportionality

when y = 180

z = 10

180 = 10k

Divide both sides by 10

k = 18

The formula for the variation is

y = 18z

When z = 14

y = 18(14)

<h3>y = 252</h3>

Hope this helps you

Find the image of U'( -8 , 1) after a translation along &lt; 2 , 0 &gt; and a reflection in the x axis
Lana71 [14]

Given:

The point is U'(-8,1).

It is translated along <2,0> and reflected across the x-axis.

To find:

The image of U'.

Solution:

The given point is U'(-8,1).

It is translated along <2,0> . So, the rule of translation is:

(x,y)\to (x+2,y+0)

U'(-8,1)\to U_1(-8+2,1+0)

U'(-8,1)\to U_1(-6,1)

Then, it is reflected across the x-axis. So, the rule of reflection is:

(x,y)\to (x,-y)

U_1(-6,1)\to U''(-6,-1)

The image of U'( -8 , 1) is U''(-6,-1).

Therefore, the correct option is A.
