Answer: 15x^2-8x+1
First Factor
(5x-1)(3x-1)
set each factor equal to zero
5x-1=0   3x-1=0
solve for x
5x=1      3x=1
x=1/5     x=1/3

Which numbers should be multiplied to obtain 175^2 − 124^2?51 and 299

51 and 51

30501 and 30749

2601 and 2601

Answers

you have to multiply 51 and 299 you will gets 15249 wich is the same as 175^2 - 124^2

Your Answer:

A.) 51 and 299

Step-by-step explanation:

In order to find out what other numbers are multiplied to obtain x, our unknown value, we must first square 175² - 124². 175² is equal to 30625 and 124² is equal to 15376. When we subtract 30625 and 15376, we get 15249. Now that we have found out our once unknown value, we will multiply the numbers from the list of choices to see which to values lead up to the product 15249. After multiplying 51 and 299, we find that they equal 15249, our desired answer.

Hope this helps y'all :D

Which number line shows the solution 1/2x-2>0

Answers

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

(1)/(2)x-2>0

Solve for x

(1)/(2)x>2

x>4

The solution is the interval ------> (4,∞)

All real numbers greater than 4

In a number line, the solution is the shaded area at right of x=4 (open circle, the number 4 is not included in the solution)

see the attached figure

Answer

On 4 there is a circle and the line goes to the right

Which statement about scatter plots is true?Associated variables cannot be represented on scatter plots.



A regression line must pass through all the points on the scatter plot.



A regression line cannot help predict future values of variables.



Scatter plots can be used to represent quantitative data.

Answers

Answer:

On the Scatter Plot, the two variables associated with each other when represented in Quantitative form that is in the form of x-values and y-values, it can be drawn in two dimensional coordinate plane, Representation being a line.

1.The Line may pass through all the points , a single point or none of the points.

2. It can also predict the future values that is for given x , we can find y and for given y , we can find x.

So, only option (4) which is,Scatter plots can be used to represent quantitative data is true.

The answer is letter D.

How much milk is in a can 8cm by 12cm<br />

Answers

Knowing the diameter of the can is 8cm, we can figure out the radius by dividing it by 2. The radius is 4cm. To find the volume of the can, multiply pi by radius^2 by height. (3.14)*(4)*(4)*(12)=(3.14)*(16)*(12)= (3.14)*(192)= 603 cm^3.
