Ksenya-84 [330]

Answer:

<h2>1.5</h2>

Step-by-step explanation:

We are given two points. Let the points be A and B

A ( 8 , -2 ) ------> ( x1 , y1 )

B ( 12 , 4 ) ------> ( x2 , y2 )

Now, let's find the slope of the given points:

slope \:  =  \frac{y2 - y1}{x2 - x1}

plug the values

=  \frac{4 - ( -2)}{12 - 8}

When there is a ( - ) in front of an expression in parentheses , change the sign of each term in the expression

=  \frac{4 + 2}{12 - 8}

Subtract the numbers

=  \frac{4  + 2}{4}

Add the numbers

=  \frac{6}{4}

Reduce the fraction with 2

=  \frac{3}{2}

= 1.5

Hope this helps..

Best regards!!

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
GalinKa [24]

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Find the values of x and y.<br> 2(5x- 5)°<br> (5y + 5)º (7y - 9°<br> (6x + 50)
Amanda [17]

The values of x and y are 15 and 7 respectively

The angles formed from the intersection of two lines at X are equal and vertically opposite angles.

From the figure shown, we can conclude that:

2(5x-5) = 6x + 50 (vertically opposite angle)

Expand

10x - 10 = 6x + 50

10x - 6x = 50 + 10

4x = 60

x = 60/4

x =15

Similarly;

5y + 5 = 7y - 9

Collect the like terms;

5y - 7y = -9 - 5

-2y = -14

y = 14/2

y = 7

Hence the values of x and y are 15 and 7 respectively

One of the factors of 34 is chosen at random. What is the probability that the factor is itself a two digit number?
solong [7]
A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?

The positive whole-number factors of 30 are:

1, 2, 3, 5, 6, 10, 15 and 30.

So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that

P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
