If: 20x+5y = 15 Then: y = -4x+3
4x2 - 7x - 15?
(4x + 5)(x - 3)
What is 4x2-13x-12 divided by 4x plus 3?
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
How do you factor this expression completely 3x2 4x-15?
(3x - 5)(x + 3)
What is the constant of this expression 5-4x plus x-3?
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
Three more than the product of a number and 4 is 15 Find the number?
3+4x=15 4x=15-3 4x=12 x=12/4 x=3 The check is: If x=3 then, 3+ (4 X 3)=15 3+12=15
Darius is asked to solve the equqtion x plus 5 equals 4x over 3?
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15
How do you solve 20x plus 5y equals 15?
If: 20x+5y = 15 Then: y = -4x+3
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
Is 4x plus 12 and 4x plus 3 equal?
8x + 15
Factor 8x2 plus 15 plus 26x?
8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
How do you factor 4x2 4x-15?
If that's - 4x, the answer is (2x + 3)(2x - 5) If that's + 4x, the answer is (2x - 3)(2x + 5)
What is the factor for thetrinomial 4x squared -7x -15?
(4x + 5)(x - 3)
What is 7x - 4x plus x - 15?
To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.
