What is the prime factorization of 1,260? A. 2 × 2 × 3 × 3 × 5 × 7
B. 4 × 5 × 7 × 9
C. 2 × 3 × 5 × 6 × 7
D. 2 × 3 × 5 × 7

Answers

A. 2*2*3*3*5*7

Whilst B and C both also yield 1,260, they aren't broken down in to their prime factors. In B, 4 can be broken down in to 2*2 and 9 in to 3*3, and in C, 6 can be broken down in to 2*3

And D just doesn't total 1,260

SOMEONE PLEASE HELP!!

Answers

Remember, one whole circle is 360 degrees. This means that the side that looks to be the same as 43 degrees is 43 degrees. The side that looks the same as (6x+5) should be (6x+5).

Now just set up your equation like this and solve:

43+43+6x+5+6x+5=360

Hope I could be of help! :)

Translate the word phrase into a variable expression. please helpEight less than the quotient of x and 3.

A.
3x – 8

B.x/3-8


C.x-8/3


D.8-x/3

Answers

Quotient means the answer to a division problem. 8 less than the quotient indicates that we have to subtract 8 AFTER we do the division... so your expression would be

(x ÷ 3) - 8 or

x/3 - 8

Answer B

Which of the following are point-slope equations of the line going through (-5, 6) and (1, 1)? Check all that apply.

Answers

Here, first we need to calculate the slope of the line, 
m = y2 - y1 / x2-x1
m = 6 - 1 / -5-1
m = 5/-6
m = -5/6

Now, Take first coordinate: y - 6 = -5/6 (x + 5)
Second coordinate: y - 1 = -5/6 (x - 1)

In short, Your Answers would be Option A & E

Hope this helps!

What is the inverse of y=4x-2

Answers

y=4x-2\n \nreverse \ the \ x \ and \ y \ to \ get \n \n x=4y-2 \n \n solve \ for \ the \ new \ y \ to \ get \n \n4y =x+2 \ \ / :4 \n \ny=(x)/(4) + (2)/(4) \n \ny=(1)/(4)x + (1)/(2)\n \n The \ answer \ is : \n \n y=(1)/(4)x + (1)/(2)
 y=4x-2

change:

x = 4y - 2
4y = x + 2
y = x/4 + 1/2   <--- inverse

It takes 8 minutes for Byron to fill the kiddie pool in the backyard using only a handheld hose. When his younger sister is impatient, Byron also uses the lawn sprinkler to add water to the pool so it is filled more quickly. If the hose and sprinkler are used together, it takes 5 minutes to fill the pool. Which equation can be used to determine r, the rate in parts per minute, at which the lawn sprinkler would fill the pool if used alone?
