Novosadov [1.4K]

Answer:

(d) y= (1 1/9)x

Step-by-step explanation:

A proportional relation is described by the equation ...

y = kx

Dividing by x shows how to find the value of k:

k = y/x

For the given values of y and x, the value of k is found to be ...

k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

y = (1 1/9)

Evaluate the given expression if x = 25, y = 10, w = 11, and z = 18.<br><br> (see the image)

hammer [34]

Answer:

Step-by-step explanation:

So we have the expression:

$(x-y)^2+10wz$

And we want to evaluate it when x=25, y=10, w=11, and z=18.

So, substitute these values for the variables:

$=(25-10)^2+10(11)(18)$

First, subtract within the parentheses:

$=(15)^2+10(11)(18)$

Square 15:

$=225+10(11)(18)$

Now, multiply the terms on the right. 10 times 11 is 110:

$=225+110(18)$

Multiply:

$=225+1980$

Finally, add:

$=2205$

So, our answer is D.

And we're done!
