<h2>GOOD LUCK ON SOLVING THAT KIDDO! </h2>
Answer:
1. Not a direct variation
2. Direct variation (constant= -4)
3. Direct variation (constant= -1)
Step-by-step explanation:
A direct variation is a function of the type
y = k*x, where k can be any real number
First case
1. y=4x+9
The term 9 interferes with the expression (it creates an offset for the value)
2. 2y=-8x
It is a direct variation, y = -4x
3. x+y=0
It is a direct variation, y = -x
The value of (x,y) is (1.2 , -4.7) , Option D is the right answer.
The complete question is
On a coordinate plane, a line is drawn from point a to point b. point a is at (7, negative 2) and point b is at (negative 8, negative 9). what are the x- and y-coordinates of point c, which partitions the directed line segment from a to b into the ratio 5:8? round to the nearest tenth, if necessary. x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 (–2.2, –6.3) (–2.4, –6.4) (2.7, –0.7) (1.2, –4.7)
<h3>What are Coordinates ?</h3>
Coordinates are the location of a point in an (x,y) plot.
The given data is
Coordinates of
A = (7,-2)
B = (-8,-9)
m:n = 5:8
The coordinates of partition has to be determined
The formula used is

(x,y ) = (1.2 , -4.7)
Therefore Option D is the correct answer.

Answer
Eli:180 Freda:260 Geoff:360
Step-by-step explanation:
First you need to make a ratio. to make the ratio you need to add up all the years of age then divide 80 by it which is 20. Now we can say 1 year being alive is 20 candy (1:20). Now we plug in numbers (9:180) (13:260) (18:360).
