What is linear equation?
An equation between two variables that gives a straight line when plotted on a graph.
2x + 5xy - 3 = 0
x (2 + 5y) -3 = 0
x ( 2 + 5y ) = 3
2 + 5y = 3 / x
5y = (3/x) - 2
y = ( (3/x) - 2) / 5
According to the graph i don't think it's a linear equation.
No, a function can only have one variable.
Answer:
The answer is C, $75.60.
Step-by-step explanation:
1) Add the price of the two necklaces.
42 + 28 = 70
2) Find what is 8% of 70. (Taxes)
70 x 8 = 560
560/100 = 5.6
3) Add the tax (5.6) to the total cost (70)
70 + 5.6 = 75.6
Answer:
y=1/5x-4
Step-by-step explanation:
So, first we're gonna put this into point slope form, (y-y1)=m(x-x1), then we'll convert it. When you plug the numbers in, you get (y+9)=1/5(x+25)
Then, you simplify!
y= 1/5(x+25)-9
y=1/5x+5-9
y=1/5x-4
Hope this helped!
