Answer: 2) 4x - 8 - 8y

Step-by-step explanation:

if xy=4

then y(x-4)(x+2) use foil method with parenthisies to get

y(x²+2x-4x-8) foil again

x²y+2xy-4xy-8y plug 4 in for xy

x²y+2(4)-4(4)-8y solve what u can

x²y+8-16-8y= x²y-8-8y

for x²y if you take out the exponent you have an xy and an x so when u plug in 4 you get 4x ending up with a solution of

4x-8-8y

Hope that helped

Answer:

The number that cannot be the largest possible 6-digit number is;

(D) AAABCB

Step-by-step explanation:

From the question, we have;

A, B, and C = Distinct digits, therefore, A ≠ B ≠ C

The number of digits in the number to be formed = 6 digits

The number of 'A' in the number to be formed = 3

The number of 'B' in the number to be formed = 2

The number of 'C' in the number to be formed = 1

We have;

When A > B > C

The largest possible number = AAABBC

When C > A > B

The largest possible number = CAAABB

When B > A > C

The largest possible number = BBAAAC

When A > C > B

The largest possible number = AAACBB

Therefore, given that when A > B > C, the largest possible number = AAABBC, we have;

AAABBC > AAABCB, because B > C, therefore, within the tens and unit of the two 6 digit numbers, we have, BC > CB

∴ AAABBC > AAABCB and <u>AAABCB</u>, cannot be the largest possible 6-digit number

What is the probability of rolling a number less than 4 on a number cube labeled 1 through 6?

Leya [2.2K]

No matter the number of times you rolled the dice, the probability of getting a number is always 1/6. But here we can choose 4 numbers ( 1 to 4) hence the probability P( 1 or 2 or 3 or 4) = 4/6 2/3 = 0.6667 = 66.67% (A)

katie has red 32% of a book if she has to read 80 pages how many more pages does Katie have left to read

galben [10]

In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
   = 256/10
   = 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
   = 54.4 pages
So Katie has 54.4 pages left to read.

How can you find the slope of a line and use it to<br> solve problems?

ziro4ka [17]

Answer:

Step-by-step explanation:

1) Mark two points on the line in the graph.

2) Determine the rise and run. Rise ---> difference in y-coordinates. (y2-y1)

Run -----> difference in x-coordinates (x2 - x1)

3) Plugin the values in the below mentioned formula.

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

1.If slope = 0, then the line is parallel to x-axis.

2. If slope is undefined, then the line is parallel to y-axis.

3. If slope is +ve, then the line slant upwards and if slope = -ve, then the line slant downwards.

72 is 25% of students that have a cat, how many total students are there?

Lemur [1.5K]

Answer:

the answer is 288 because 72 would be one fourth or 25% of 288. 72 plus 72 plus 72 plus 72 equals 288 equals 100%
