The sum of cubes formula:
The following equations should be the true choices to solve for this.
x + y = 86 (total number of items)
2x + 5y = 330 (total cost)
Answer:
x equals 1 and 5
Step-by-step explanation:
x^2-6x+5
Factor: (x-1) (x-5)
The Zeroes: 1 and 5
The zeroes are the numbers that make the equation equal to zero.
Answer:
Please see attached graph.
Step-by-step explanation:
The equations for straight lines are given as:
i) y = x +4
ii) y= x-4
Yon can form a table for values of x and y that are true for an equation and use these values as coordinates ( x,y ) to plot the graphs and view the lines to select the correct labels for the equations.
For i)
y= x+4
x y coordinates
-3 1 (-3,1 )
-2 2 (-2,2)
-1 3 (-1,3)
0 4 ( 0,4)
1 5 ( 1,5)
2 6 ( 2,6)
3 7 ( 3,7)
Plot the points on a graph tool and draw the line. Do the same for the second equation to view both graphs as shown in the attached graph.
