How To Solve Y = 5x -3 For x = -4,0 & +4 ?
回答 (6)
✔ 最佳答案
y = 5x - 3 (x = -4)
y = 5(-4) - 3
y = -20 - 3
y = -23
y = 5x - 3 (x = 0)
y = 5(0) - 3
y = 0 - 3
y = -3
y = 5x - 3
y = 5(4) - 3
y = 20 - 3
y = 17
y = - 20 - 3 = - 23
and
y = 20 - 3 = 17
Substiute you X values into the equation then work it out from there.
when x = -4:
y = (5*-4) - 3
y = -23
when x = 0:
y = (5*0) - 3
y = -3
when x = 4:
y = (5*4) - 3
y = 17
* denotes multiplication
Put -4 and 4 in for x in the equation.
y = 5 (-4) -3
y=5 (4) -3
