5y-45 = -40
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 .
8x-5y = -40 -5y = -8x-40 y = 1.6x+8 which is now 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
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
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
5y-45 = -40
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 .
8x-5y = -40 -5y = -8x-40 y = 1.6x+8 which is now 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
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
If you mean: 4x+5y = 40 then y = -0.8x+8 whereas as -0.8 is the slope and 8 is the y intercept of a straight line equation

Father's age is 5 times his son's age. 4 years back the father was 9 times older than son. Find the fathers present age. a) 45 years b) 40 years c) 50 years d) 35years Cute , he's 40 & the kid is 8 Mathematic explanation: x = father's age y = son's age x = 5y x-4 = 9(y-4) x-4 = 9y-36 x = 9y-32 5y = x = 9y-32 5y = 9y-32 4y = 32 y = 8 x = 5y = 40
First, put the equation in slope-intervcept form y=mx + b 5y=4x + 40 The y intercept is where x=0 so- 5y= 4(0) +40 solve for y y intercept = (0,8) For the x intercept, y=0 0=4x+40 -4x=40 x= -10 xintercept =( -10.0)
5 times y is the same as 5y in algebra
