Answer:
y=6x
Step-by-step explanation:
g=-9/2
c=0
y=-9/2x
3/4x*-9/2
y=6x
First, you need to get delta which is b squared minus 4ac. If delta is higher than cero, the polynomial has two solutions, if it is less, the polynomial has no real solutions and if it is the same, it has one solution.
Although that is only for second grade ecuations
Answer:
circle area
Step-by-step explanation:
A full circle contains 360 degrees. So, an arc of 360 degrees would just be a circle.
Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
Domain = -4<=x<=5
Range = -4<=y<=4
Yes it is a function because each input maps to exactly one output.
