The expression Z₁ -Z₂ is 4 - (4√3 -16)i.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
The given expression Z₁ = 4 - 4√3i.
And Z₂ = -16i
Subtract Z₂ to Z₁:
Z₁ -Z₂
= 4 - 4√3i - (-16i)
= 4 - (4√3 -16)i.
Therefore, Z₁ -Z₂ is 4 - (4√3 -16)i.

#2. A field of grass feeds 36 cows for 4 days. How
many days would the same field feed 20 cows?
162 cow-days
Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.
Please consider marking brainliest! :)
Using the principle of proportional relationship, it will take 20 cows 7.2 days.
Setting up the relationship thus :
36 cows = 4 days
Hence, if they eact at the same rate ;
1 cow = 36 × 4 = 144 days
Hence, for 20 cows, it will take;
144 days ÷ 20
= 7.2 days
Hence, 20 cows will feed on the grass for 7.2 days

What is the slope and y-intercept of the function represented by the table
slope =
y-intercept =
Answer:slope = -2/3
Y inter. =7
Step-by-step explanation:
To get the slope= y-y divide x-x which is = 3-5 divide 6-3
= -2/3
So the equation will be :
Y=mx+b
Y=-2/3x+b
Now to get the b which is the yinter. We have to put a “x” and a “y “
Lets put (3,5)
5=-2/3 x (3) +b
5= -2 + b
7=b
Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?
Distribute –4 to get –8x + 4 > 5 – 3x.
Distribute –4 to get –8x – 1 > 5 – 3x.
Subtract 2x from both sides of the inequality.
Add 1 to both sides of the inequality.
Answer:
Step-by-step explanation:
Distribute –4 to get –8x + 4 > 5 – 3x.
We can actually deduce here that the correct first step in solving the inequality –4(2x – 1) > 5 – 3x is: A. Distribute –4 to get –8x + 4 > 5 – 3x.
What is inequality?An inequality refers to the relationship that exist between two expressions that shows that they are not equal to each other. The signs used in an inequality are:
≠ ‘not equal to’, > ‘greater than’, < ‘less than’, etc.We see here that the first step is to use -4 to multiply the digits in the bracket. If that happens, we will have: –8x + 4 > 5 – 3x.
Then solving the inequality:
-8x + 3x > 5 - 4
-5x > 1
x < -1/5
Thus, we see that option B: Distribute –4 to get –8x + 4 > 5 – 3x. is the correct answer.

Mathematically;
density = mass/volume
Thus;
density = 13 pounds/ 102 in^3
density = 0.1275
To the nearest hundredth, this is 0.13 pounds per in^3

Answer:
The greatest common factor of 128 and 192 is 64, because 64 is the highest number that is divisible by both numbers.
The greatest common factor of 128 and 192 is 64 because 64 is the highest number that is divisible by both numbers.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.
Given that the two numbers are 128 and 192. The greatest common factor is the largest number which is divided into both numbers.
128 = 2 x 2 x 2 x 2 x 2 x 2 x 2
192 = 2 x 2 x 2 x 2 x 2 x 2 x 3

Pablo created the bar model and equation after paying a $9.79 lunch bill with a $20 bill.
A bar diagram. The top bar contains 20.00. The bottom bars contain c and 9.79.
20.00 = c + 9.79
What is the value of c, and what does it represent in this problem?
The value is $10.21, and it shows the cost of Pablo’s lunch.
The value is $29.79, and it shows the cost of Pablo’s lunch.
The value is $10.21, and it shows the change Pablo received.
The value is $29.79, and it shows the change Pablo received.
Answer:
The value of "c" represents the amount of change that Pablo will receive
Step-by-step explanation:
If you pay 9.79 in lunch with a 20 dollar bill, you would have 10.21 in change.
Let's use the equation given to us:
20.00 = c + 9.79
now let's subtract 9.97 on both sides of the equation:
20.00 - 9.79 = c + 9.79 - 9.79
we're left with:
10.21 = c
this is how much money we're left with after we pay for lunch, which is the change given to us. Therefore,
c = the amount change Pablo will have after he pays for his lunch
