Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.

I'll help you by example. Let's look at the first problem:

"Evaluate 6(z-1) at z-4."

Due to "order of operations" rules, we must do the work inside the parentheses FIRST. Replace the z inside (z-1) with "-4". We obtain

6(-4-1) = 6(-5) = -30 (answer.)

Your turn. Try the next one. If it's unclear, as questions.

Quadrilateral ABCD is located at A(-2, 2), B(-2, 4), C(2,4), and D(2, 2). The quadrilateral is then transformed using the rule (x - 3, y + 4) to form the image A’B’C’D’. What are the new coordinates of A’,B’, C’, D’? Describe what characteristics you would find if the cooresponding vertices we’re connected With line segments

Answers

Answer:

Step-by-step explanation:

Given coordinates are-

A(-2,2) , B(-2,4) , C(2,4) , D(2,2)

Now, this coordinates will be changed using the following formula-

x'=x-3 , y'=y+4

That is , we have to subtract 3 from x-coordinate and add 4 with y-coordinate to get the new points.

So,

A'=(-2-3 , 2+4)=(-5 , 6)

B'=(-2-3 , 4+4)=(-5 , 8)

C'=(2-3 , 4+4)=(-1 , 8)

D'=(2-3 , 2+4)=(-1 , 6)

So, the new coordinates are -

A'(-5,6) , B'(-5,8) , C'(-1,8) , D'(-1,6)

And if we connect the coordinates we will get a rectangular prism.

3x + 7y =47
-4x +7y =19

Answers

3x+7y=47
-1(-4x+7y=19)

Distribute the -1 and add the equations together...you'll get:

7x=28
x=4

Plug X=4 back in...
12+7y=47
7y=35
y=5

a ferris wheel can accommodate 55 people in 15 minutes. how many people could ride the ferris wheel in 6 hours? what was that rate per hour

Answers

15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour.
Then, multiply the number of people per hour by the 6 hours:
6 hours x 220 people =1320 people in 6 hours.

55 per 15 x4 60x 6= 6 hours
55 times 4 times 6 and 1,320 rode on it

What does mean, median, mode, and the other word mean

Answers

Mean: add all the numbers and divide by the number of numbers
so if I had 1, 2, 2, 3, 4, I would add all of them together and get 12 then divide 12 by 5 because there are 5 numbers to get a mean of 2.4

Median: the middle number in a set
in the set 1, 2, 2, 3, 4 the median would be 2 as it is in the exact middle of the set of numbers. ***Be careful! For this, the numbers HAVE to be in numerical order so it has to be 1, 2, 2, 3, 4 NOT something like 1, 2, 3, 2, 4

Mode: the number that appears the most in a set
in the example 1, 2, 2, 3, 4 the mode is 2 because 2 appears more than the other numbers

Hope this helped!!

so mean is when you add all the number you have and divide it how many number.

example: 1,4,5.6 if you add all the numbers the answer will be 16 and divide it 4 so you count how many number you have so 16 divide by 4 = 4.

the median is the one that are in the middle . to find it you have to place the number to least to greater and find the median.

Example: 4,6,10.5,3,1,8

so least to greater will be 1,3,4,5,6,8,10. so when you count the median will be 5 because you count 1,3,4 and you count 6,8,10 so the middle is 5.

the mode is the number that occurs most often in the number like this

Example: 1,2,3,3,4,5, so the number that occurs most often is 3 .
