Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)
141 (The original number) ;1 + 4 + 1 = 6 (Add each individual digit together) ;6 is divisible by 3 ;Then 141 is divisible by 3 ;141 isn't a prime number ;In the same way, 171 is divisible by 9 ; then, 171 isn't a prime number ;
161 = 7 x 23; 161 is divisible by 7 ; then, 161 isn't a prime number ;
Test whether 171 is divisible by 2, 3 , 5 , 7 , 11 , 13 ( <span>an algorithm that tests each incremental </span>m<span> against all known primes < </span> division ) ;
but, 171 isn't divisibile by 2,3,5,7,11,13 ;
Finally, 171 is a prime number ;
Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :
C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
Answer:
<h3>Step 4</h3>
Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4
