This polynomial will be 3 with the leading coefficient of 1
Answer:
16 = <u>3x</u>
Step-by-step explanation:
It is an equilateral triangle. The formula for the perimeter of an equilateral triangle is P = 3a.
In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
The slope is the same as rate of change. In a linear graph, it is the change in y over the change in x.
Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
