3X - 4Y = 9
-3X + 2Y = 9
first step is try to get rid of one of the variables and solve for the other one. In this example you dont need to manipulate the equations to get one variable to cancel.
the x term cancels out. add both equations
-2y = 18
y= - 9
now we plug the y term back into an original equation and solve for x
3x - 4(-9)=9
3x=-27
x=-9
hope that helps
Yes 128 more than the product of v and 25 is the same
Answer:
yes
Step-by-step explanation:
according to cyclic quadrilateral properties the oppoaite angles are supplementry
So first, plot your point at (0,0) then use rise over run. From (0,0) go up 3 units then right 4 units, and keep going. Then when you go down go -3 units and left 4
Answer: 1/20
Step-by-step explanation: = 1+8:36= 9 hours and 36 minutes
= 9+ 36/60= 9 3/5 hours
=48/5
Decrease per hour= 12/25 divided by 48/5
= 12/25 times 5/48= 1/20
Ans 1/20
