Lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. Her work follows, but the last two lines of work are missing.

Which answers correctly fill in the blanks?

Select two answers: one for blank 1 and one for blank 2.

Answers

Answer:

Blank 1: 2xy(4x-5)=3(4x-5)

Blank 2: (2xy+3)(4x-5)

Step-by-step explanation:

The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.

The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.

The only correct answer are:

Blank 1: 2xy(4x-5)=3(4x-5)

I think it’s exponential because there isn’t a cube root or anything but your still multiplying the numbers so if you were to graph it on a calculator it should pop up as a line but it’s not linear because there’s no addition in the function.

A pet store sells mice, reptiles, and birds.
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
What does P(A or B) = 0.25 mean in terms of this problem?
A. Buying a mouse and buying a bird are mutually exclusive events.
B. The probability that a customer buys neither a mouse nor a bird is
25%.
C. The probability that a customer buys both a mouse and a bird is
25%.
D. The probability that a customer buys either a mouse or a bird is
25%.

Answers

D. the probability that a customer buys EITHER a bird or a mouse.

The correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

What is probability?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given that, a pet store sells mice, reptiles, and birds,

Let event A = A customer buys a mouse.

Let event B = A customer buys a bird.

We need to tell that,

What does P(A or B) = 0.25 mean in terms of this problem,

So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,

Hence, the correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches

Answers

Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

Raleigh went to a gaming arcade for his birthday. His parent gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on the gaming arcade. Each Game in the arcade cost $1.25. Write a linear inequality to represent how many games g Raleigh can play in the arcade

Answers

Answer:

Step-by-step explanation:

Let [tex]g[/tex] denotes number of games that Raleigh can play in the arcade.

Cost of 1 game = $1.25

Cost of [tex]g[/tex] games = [tex]\$1.25g[/tex]

Amount spent in food and drinks = $14.25

Total amount spent by Raleigh = [tex]14.25+1.25g[/tex]

Also, amount with Raleigh = $55

So, the inequality is [tex]14.25+1.25g\leq 55[/tex]

Divide the inequality by 5

[tex]2.85+0.25g\leq 11[/tex][tex]2.85+0.25g\leq 11[/tex]

5) y = -8x -4

6) y = 2x + 3

Step-by-step explanation:

Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.

The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3
