Answer:
(3,2)
(-9,-6)
Step-by-step explanation:
Given that the graph is a direct variation.
The equation of variation is:
Since point (6, 4) is on the graph
Therefore, the equation connecting x and y is:
Therefore, the points that are also on the graph are:
(3,2) and (-9,-6)
Answer:
Step-by-step explanation:
LET ORANGES=X
PEARS ARE 3 TIMES =3X
LET CHILDREN=Y
IF WE GIVE 5 ORANGES PER CHILD WE NEED 5Y ORANGES.SO THIS =X
X=5Y........................I
IF WE GIVE 8 PEARS PER CHILD WE NEED 8Y PERARS...THERE ARE STILL 21 PEARS LEFT OUT AFTER THIS THAT IS
8Y+21=3X....................II
SUBSTITUTING FOR X FROM EQN.I..
8Y+21=3*5Y
15Y-8Y=21
7Y=21
Y=3
X==5Y=5*3=15..
SO CHILDREN =3
ORANGES=15
PEARS=3*15=45
THANKYOU AND PLEASE AMRK IT BRAINLIEST
A would be 1 as b would be -4
Answer:
15
Step-by-step explanation:
The first ratio is 1:3
12/36 = 3
So,
5 x 3 = 15
