Answer:

25

Step-by-step explanation:

"y varies inversely with x" means:

y = k / x

where k is a constant.

When x = 5, y = 10.

10 = k / 5

k = 50

y = 50 / x

When x = 2:

y = 50 / 2

y = 25

Polygon Q(16, 4), R(8, 16), S(4, 4) was mapped to polygon T(–2, 5), U(–4, 8), V(–5, 5). First by the dilation: (x, y) → (0.25x,

Answer:

D M: (x, y) → (x – 6, y + 4)

Step-by-step explanation:

Polygon Q(16, 4), R(8, 16), S(4, 4) was mapped to polygon T(–2, 5), U(–4, 8), V(–5, 5). First by the dilation: (x, y) → (0.25x, 0.25y).

This means that:

Q(16,4)\to (0.25\times 16,0.25\times4)=(4,1)

R(8,16)\to (0.25\times 8,0.25\times16)=(2,4)

S(4,4)\to (0.25\times 4,0.25\times4)=(1,1)

Now we want to find the translation rule that takes

(4,1) to (-2,5)

(2,4) to (-4,8)

(1,1) to (-5,5)

In each case, 6 is subtracted from the first coordinates and 4 added to the second coordinates.

Therefore, the translation rule is:

(x-6,y+4)

Option D is correct.

Answer:

Step-by-step explanation:

For the first 30 hours, Andrew will earn 4(30) = $120.  For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30).  Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:

 

w = 120 + 5(h - 30).  

 

So, if he works 35 hours, he will earn:

 

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

 

If he works 42 hours, he will earn:

 

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

 

I hope this helps!
