How do you solve 6y3 plus 8y2-15y-20 by factoring?
6y3 + 8y2 - 15y - 20 is an expression, not an equation (or inequality). An expression cannot be solved.The expression factorises to (3y + 4)*(2y2 - 5)
What are the intercepts of the line 3x 15y 60?
x=20 y=-3
What is the algebraic equation for 13 and a number plus seven equals 5 and a number minus 20?
13 + a + 7 = 5 + b - 20. This assumes the two numbers are different.
Solve by the substitution method 15x-20y equals -1 15y equals 2 plus 5x?
Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1
Solve the system using any algebraic method a. -5x-y equals -3 ---- x-4y equals 9 b. x plus y-z equals 7 ---- 2x-3y plus z equals 2 ---- 4x plus 2y-2z equals 20?
y=5x+2 if y equals -4
How do you solve 3xy-4x plus 15y-20?
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
Factorise 15y plus 20?
15 y + 20 = 5(3y + 4)
