Answer:
(-2, 3)
Step-by-step explanation:
The +5 represents shifting 5 units up, so we can add 5 to the y coordinate.
This gives us (-2, -2+5)=(-2, 3)
Find the center and radius of a circle that has a diameter with the given endpoints.
(7, -5) and (-1, 10)
Answer:
center: (3, 2.5)radius: 8.5 unitsStep-by-step explanation:
The center of a circle is the midpoint of any diameter. The midpoint of a segment has coordinates that are the average of the coordinates of the segment end points.
The length of the radius is the distance from the center to an end point of a diameter. Alternatively, it is half the length of the diameter.
__
Center = (A +B)/2 = ((7, -5) +(-1, 10))/2 = (6, 5)/2 = (3, 2.5)
Radius = 1/2|AB| = 1/2√((7 -(-1))² +(-5 -10)²) = 1/2√(64 +225) = 1/2√289
= 17/2 = 8.5
The center of the circle is (3, 2.5), and the radius is 8.5 units.
__
Additional comment
The differences of diameter end point coordinates are 8 and 15, suggesting the Pythagorean triple {8, 15, 17} will come into play. It does.
Find the midpoint of the line segment with end coordinates of: (−4,−2) and (−2,−10).

The ordered pairs for two points are listed in the table. What is the equation, in slope-intercept form, of the line that contains these points?
A. y = -6x + 2
B. y = -6x - 2
C. y = -2x + 6
D. y = -2x - 6
Answer:
D) y = -2x - 6
Step-by-step explanation:
Given:
[tex]\mathsf{(x_1,y_1)=(3,-12)}[/tex][tex]\mathsf{(x_2,y_2)=(-3,0)}[/tex][tex]\mathsf{slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0--12}{-3-3}=-2}[/tex]
Using the point-slope form of a linear equation: [tex]\mathsf{y-y_1=m(x-x_1)}[/tex]
[tex]\implies \mathsf{y-(-12)=-2(x-3)}[/tex]
[tex]\implies \mathsf{y=-2x-6}[/tex]
if the cost of 56m cloth is 10rs, find the cost of 15m cloth?
Answer:
2.67857142855
Step-by-step explanation:
every M of cloth costs 0.17857142857rs (10/65=0.17857142857)
So, 15m of cloth costs 2.67857142855rs (0.17857142857*15= 2.67857142855)
Answer:2.7rs
Step-by-step explanation:
First find the cost of one m:
We can set it up as a fraction in the form of cloth (mm)/cost(rs)
=
56m/10rs
let x be the cost in rs of 1m:
1m/x
This is kind of like a ratio where 56/56=1 so therefore 10/56 (because whatever you do to the top you do to the bottom) will give us x or in other words the cost of 1 meter of cloth:
so after dividing both 56 and 10 by 56 we get:
1/0.18 (it would be a longer decimal but always try to round it if you can!)
That mean 1m of cloth costs 0.18 rs
So now let’s apply the same rule as before (treating the fraction as a ratio and doing the same on both top and bottom and let’s apply it again to find the cost of 15 meters!)
1m * 15
————-
0.18 * 15
=
15m
———-
2.7rs
therefore the cost of 15 m is 2.7rs
confirm with your teacher wether they want you to round it or not however.
Hope this helps!

Step-by-step explanation:
as the question told you, if there're 5 counselors, there's a maximum for students of 15. and for 15 counselors, there's a maximum for students of 45. we can easily see that every one counselor can only have 3 students. therefore, you should draw each dot with respect to the counselors' amount, but because two points determine one line, all you need to do is draw (5,15), (15,45) and line them from 0 to 50.

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?
The selection of the committee members is an illustration of combination
There are 150150 different ways of selecting the committee
How to determine the total selectionThe number of members (n) is:
n = 15
The members on the committee are (r):
r = 4
So, the number of selection is:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15!}{(15 - 4)!4!}[/tex]
Evaluate the differences
[tex]^{15}C_4 = \frac{15!}{9!4!}[/tex]
Expand
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10 * 9!}{9!4!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10}{4!}[/tex]
[tex]^{15}C_4 = 150150[/tex]
