Answer:
A and B
A and C
Step-by-step explanation:
Common internal tangents intersect the segment joining the centers of the two circles.
Tangent I is common internal tangent to circles A and B as the line joining the centers of circles will intersect the tangent I.
Tangent I is also a common internal tangent to circle A and C.The line joining the centers of circles A and C intersects tangent I .
Tangent I is not a common internal tangent to circles B and C,
The distance between the points (4, 3) and (1, -1) on the coordinate plane will be 5 units. Then the correct option is C.
<h3>What is the distance between two points?</h3>
The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D² = (x - p)² + (y - q)²
The points are given below.
(4, 3) and (1, -1)
Then the distance between the points will be
D² = (4 - 1)² + (3 + 1)²
D² = 3² + 4²
D² = 9 + 16
D² = 25
D = 5 units
Then the correct option is C.

Answer:
B
Step-by-step explanation:
If you arrange a statistics in order from least to greatest, the middle number is the median.
If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.
Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.
Since they are arrange in order we check each:
Jon = average of 6 and 7, (6+7)/2 = 6.5
Leroy = average of 6 and 8, (6+8)/2 = 7
Simon = average of 5 and 6, (5+6)/2 = 5.5
Leroy's median is the greatest (7).
First you take 7143-6997 to get her units used( it’s 146) since you know that the first 100 units cost 24p per unit so take 100 Times 24 p to get 2400p then take the remaining 46 units times 16 to get 384p.
Add 2400p+384p to get 2784p for her bill
Answer:
Step-by-step explanation:
Your first equation is y=10x+20
Your slope is 10 and your y-intercept is 20 in this first equation
Your second equation after it has changed, your new equation is y=30x+45
Your slope is 30 and your y-intercept is 45 in this second equation
I hope this helps!
