Answer:

  A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

Step-by-step explanation:

We presume the first transformation is a translation 4 units right and 1 unit up:

  (x, y) ⇒ (x+4, y+1)

The second transformation negates the x-coordinate, so the two transformations together have the rule ...

  (x, y) ⇒ (-(x+4), y+1)

Then the transformed points are ...

 A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

maksim [4K]

Answer:

$200L+$100B ≥$5000

Step-by-step explanation:

Given :

Hyun Yong wants to donate more than $5000 in laptops and bicycles.

Each laptop that he donates is worth $200, and each bicycle that he donates is worth $100.

To Find : An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.

Solution :

L denotes the number of laptops.

Since cost of each laptop is $200

Thus cost of L laptops = $200L

B denotes the number of bicycles.

Since cost of each bicycle is $100.

Thus cost of B bicycles = $100B

Now, he wants to donate more than $5000 in laptops and bicycles

So, inequality will be : $200L+$100B ≥$5000

Hence, An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal:

$200L+$100B ≥$5000

Can someone help me with this
frez [133]

Answer:

8 laps

Step-by-step explanation:

Assuming in the equation given than n represents the number of laps run and t represents the time in minutes, when we plug in 16 in for t and simplify we get:

n=5/10*16

n=1/2*16 (Simplify the fraction by dividing top and bottom by 5)

n=16/2 (Multiply the fractions together by writing 16 as 16/1 and multiplying straight across)

n=8

What is the average rate of change for f(z) = -2z^2 - 12z -19 over the interval [ -4, -2 ]?
marusya05 [52]

Answer:

Average rate of change = 0

Step-by-step explanation:

f(z) = -2z^2 - 12z - 19

a = -4 and b = -2

[f(b) - f(a)] / (b-a)

[-2(-2)^2 - 12(-2) -19] - [-2(-4)^2-12(-4)-19] / (-2 -(-4))

(-8+24-19) - (-32+48-19) / 2

(-8+24-19+32-48+19) / 2 = 0/2
