Answer:
The coordinates of k are (-2,-1)
Step-by-step explanation:
Here, we are interested in calculating the coordinates of point k.
Mathematically, we will use the internal division formula for this;
This would be;
(x,y) =( nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
where m = 1 , n = 4
x1 = -2 , x2 = 8
y1 = -4 , y2 = 11
we now make the substitutions into the formula;
(x,y) = 4(-2) + 1(-2)/(1+4) , 4(-4) + 1(11)/(4 + 1)
(x,y) = (-8-2)/5 , (-16 + 11)/5
(x,y) = -10/5 , -5/5
(x,y) = (-2, -1)
Answer:
x+5=5

Step-by-step explanation:
If you are asking what 3x2-48 is, then the rules of Pemdas would be relevant in this.
First we would multiply. So, 3 times 2 is 6.
Then, 6-48 is -42
Yes, 2.8 cm, 4.0 cm, and 2.8 cm could be the side lengths of a triangle ⇒ B
Step-by-step explanation:
In any triangle:
- The sum of any two sides is greater than the third side
- Add the smallest two numbers if their sum is greater than the largest number, then the numbers can formed the lengths of sides of a triangle
∵ The lengths of the segments are 2.8 cm , 4.0 cm and 2.8 cm
∵ The smallest segments are 2.8 cm , 2.8 cm
- Find their sum
∴ The sum of their length = 2.8 + 2.8
∴ The sum of their length = 5.6 cm
The length of the largest segment is 4.0 cm
∵ 5.6 cm > 4 cm
∴ 2.8 cm , 4.0 cm , 2.8 cm can formed a triangle
Yes, 2.8 cm, 4.0 cm, and 2.8 cm could be the side lengths of a triangle
