What is 5y-45?
5y-45 = -40
40 plus 9 equals 5y plus 9?
40 + 9 = 5y + 9 Since 9 is present on both sides of the equation,therefore we can strike it off on both sides,the remaining equation being 40 = 5y or 5y = 40 5y = 40 or y = 40/5 Therefore,y = 9 .
What is 0 equals 5y plus 20-x in slope intercept form?
0 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 4
What is the elimination method for 11x equals 5y plus 80 and 9x-15y equals 120?
A: 11x = 5y + 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 3x - 5y = 40 A - B: 8x = 40 x = 5 Now we can plug that value of x into one of the original equations to solve for y: 11(5) - 5y = 80 55 - 5y = 80 -5y = 25 y = -5
How would you turn 8x-5y equals -40 into slop intercept?
To convert the equation 8x - 5y = -40 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, you need to solve for y. First, isolate y by subtracting 8x from both sides to get -5y = -8x - 40. Then, divide by -5 to get y = 8/5x + 8, which is the slope-intercept form of the equation. The slope is 8/5 and the y-intercept is 8.
