y=−12x+. HELP PLEASE

Answer and Step-by-step explanation:

(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.

(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

Answer:

3 stamps were left over

Step-by-step explanation:

Division

When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.

But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.

Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.

1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.

How many?

Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over

Answer:

x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.

Step-by-step explanation:

2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2

(2x - 3) • 2 = x + 9

4x - 6 = x + 9 Add 6 to both sides

4x = x + 9 + 6

4x = x + 15 Subtract x from both sides

4x - x = 15

3x = 15 Divide 3 on both sides

x = 15/3

x = 5

Answer: 84

Step-by-step explanation: 48÷4= 12 so 12 times 7 is 84

Answer:

 c^2 = a^2 +b^2

 c^2 = (20 ft)^2 +(21 ft)^2 = 442 ft^2

 c = √(442 ft^2) = 21,02 ft

The length of the missing side is 21,02 ft.

Answer: 4

Step-by-step explanation:

first you remove the parentheses it should look like this (4x+8-3x=12) then you collect the like terms (like terms have the same variable to the same power) it should look like this(x+8=12). then you move the constant to the right then last you calculate it should look like this x=12-8). then you subtract 12 by 8 and 4 is what you get.

Answer:

standard error of the mean (S.E) = 0.06

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 500

Given variance of the Population = 900

The standard deviation of the Population = √900 = 30

The standard error of the mean is determined by

[tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06[/tex]

Step-by-step explanation:

No

Carbon monoxide concentrations sample in air from a large city are not normally distributed. This is often so because of the time of the day and that of the night. There exists different concentrations during the day, with respect to during the night. The companies and factories work during the day, so does most vehicles. This means that there tend to be a higher concentration during the day, than there will be during the night.

b)

Assuming that Y' is approximately normal, we can say that

P(Y' > 14) = P(Z > [√100(14 - 12)/9]) and this is equal to

P(Z > 2.22) = 0.013

Answer:

The equivalent expression is 6x+8.

Step-by-step explanation:

Given expression is:

1.5(3x + 4) + 0.25(6x + 8)

We will solve the expression and combine alike terms.

4.5x + 6 + 1.5x + 2

6x + 8

Therefore,

The equivalent expression is 6x+8.

The equivalent expression is 6x+8 is the correct answer

What is an equivalent expression for 1.5(3x + 4) + 0.25(6x + 8)?

Answer:

x = 20

Step-by-step explanation:

First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:

2x + 8 + 6x + 12 = 180

Next, we can combine like terms to simplify the equation:

8x + 20 = 180

Now, we can subtract 20 from each side:

8x = 160

Finally, we divide both sides by 8 to find the value of "x":

x = 20

Answer:

A=x2 - 2x -35

Step-by-step explanation:

x+5 x-7

The solution is Option D.

The area of the rectangle is A = x² - 2x - 35

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the value of A is

The length of the rectangle L = x + 5

The width of the rectangle is W = x - 7

And ,

The area of rectangle = L x W

Substituting the values in the equation , we get

The area of rectangle = Length of rectangle x Width of rectangle

The area of rectangle = ( x + 5 ) ( x - 7 )

On simplifying the equation , we get

The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )

The area of rectangle A = x² - 7x + 5x - 35

The area of rectangle A = x² - 2x - 35

Therefore , the value of A is x² - 2x - 35

Hence , the area of rectangle is x² - 2x - 35

Answer:

a. ∛(x+4)/3

Step-by-step explanation:

y = 3x³ -4

step 1: x = 3y³ - 4   (swap x and y)

step 2: 3y³ = x + 4

            y³ = (x + 4) / 3

            y = ∛(x+4)/3    (solve y)
