Answer:

(2x−5)(x−3)

Step-by-step explanation:

Break the expression into two groups

(2[tex]x^{2}[/tex]-5x) + (-6x+15)

Factor out an x from the first group

x(2x-5)

Factor out -3 from the second group

-3(2x-5)

Factor out the common term and combine

x(2x-5)-3(2x-5)

(2x-5)(x-3)

Answer:

k = 0.5

Step-by-step explanation:

There is a proportional relationship between the amount of time in shelling peas 'x' and the weight of the peas 'y'.

Therefore, y ∝ x

⇒ y = kx

Here, k = proportionality constant

From the given table,

If family spends the time 2 minutes (x-value) in shelling 1 pound of peas (y-value),

1 = k × 2

k = [tex]\frac{1}{2}[/tex]

k = 0.5

Therefore, proportionality constant for the relationship is 0.5.

K’: (0, 1)

L’: (-3, 1)

M’: (-2, 3)

N’: (-1, 3)

You are reflecting across the x = 2, so the line is vertical on 2 like |. It’s as many points away on each side for the other side. Ex. K is 2 points to the right of x = 2 so then it would be 2 points to the left of x = 2.

Answer:

d =  103

e =  22

f = 55

Step-by-step explanation:

ok so the angles on the other side 22 and 103 are equal to 2 of the angles on the other side

the whole line is equal to 180

103 + 22 = 125

180 - 125 = 55

d =  103

e =  22

f = 55

Answer:

d = 103

e= 22

f= 55

Step-by-step explanation:

the opposite side of d equals 103 and they are adjacent which means they have the same measure

same goes to e the opposite side of it equals 22

and then for f a full line measure equals 180

so 103+22= 125

180-125= 55

there you have it :)

The cost of 5.7 pounds of the grain is given by the proportion A = $ 3.99

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

We can use a proportion to solve this problem. Let "A" be the cost of 5.7 pounds of the grain. Then we can write:

2.2 pounds / $ 1.54 = 5.7 pounds / A

To solve for "A", we can cross-multiply and simplify:

2.2 pounds x A = $ 1.54 x 5.7 pounds

A = ($ 1.54 x 5.7 pounds) / 2.2 pounds

A = $ 3.99

Hence , 5.7 pounds of the grain will cost $ 3.99

Given:

Total of raffle tickets = 30

Number of tickets Jason bought = 10

Number of prizes = 3

To find:

The probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away.

Solution:

Total of raffle tickets = 30

Number of prizes = 3

So, number of total outcomes is

[tex]n(S)=^{30}C_3[/tex]

Number of tickets Jason bought = 10

So, number of favorable outcomes is

[tex]n(A)=^{10}C_3[/tex]

Now,

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability}=\dfrac{n(A)}{n(S)}[/tex]

[tex]\text{Probability}=\dfrac{^{10}C_3}{^{30}C_3}[/tex]

[tex]\text{Probability}=\dfrac{\dfrac{10!}{(10-3)!3!}}{\dfrac{30!}{(30-3)!3!}}[/tex]

Answer:

2

Step-by-step explanation:

the answer is 2 bc if we put the y axis as how many cats in kiki's house and x axis as how many dogs were in kiki's house, we would use this equation y=kx

the k would be our unit rate and y would be our cats, x would be dogs, so we divide y to x meaning 4 divided by 2. the unit rate would be 2.

Given:

Scott and Nikki each have a full 1.5-gallon container of liquid laundry detergent.

Lid on Scott's container can hold 3 fluid ounces of detergent.

Lid on Nikki's container can hold 4 fluid ounces of detergent.

To find:

The number of lids full of detergent Scott have more than Nikki.

Solution:

We know that,

1 gallon = 128 fluid ounces

1.5 gallon = 192 fluid ounces

Lid on Scott's container can hold 3 fluid ounces of detergent. So, number of lids full of detergent Scott have is

[tex]\dfrac{192}{3}=64[/tex]

Lid on Nikki's container can hold 4 fluid ounces of detergent.  So, number of lids full of detergent Nikki have is

[tex]\dfrac{192}{4}=48[/tex]

Difference between number of lids is

[tex]64-48=16[/tex]

Therefore, Scott have 16 lids more than Nikki. Hence, the correct option is B.

Answer:

I think its (0,-3)

Step-by-step explanation:

I took the coordinates you gave me and placed they X axis where the X was and put the Y axis where the Y was and got that answer

The required slope of the line is -3 for the equation y + 1 = -3(x-5) the line contains the point (5,-1).

The equation for a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To put the equation y + 1 = -3(x - 5) into slope-intercept form, we need to solve for y. We can do this by subtracting 1 from both sides of the equation, which gives us y = -3(x - 5) - 1. We can then distribute the -3 on the right side of the equation to get y = -3x + 15 - 1. Finally, we can simplify this to get y = -3x + 14.

In this equation, m = -3 and b = 14. We can verify that this is the correct equation by substituting the coordinates of the point (5,-1) into the equation and solving to see if the equation is true. When we substitute the values into the equation, we get -1 = -3(5) + 14, which is true.

Therefore, the slope of the line is m = -3.

Answer:

2 and 8

Step-by-step explanation:

Well. Boy A gets 1 orange, so the other must get 4. So say boy A gets 2 oranges now, so the other must get also double the amount of oranges, which is 8.

1:4

If you changed the 1 to a 2, you have x2 (you can only x or ÷, in ratio) on the other side. Whatever you do to this side, you do to the other side. So it becomes

2:8

Add the numbers together to find the total number of parts. You get 10 in this ratio, so it must be the answer.
