Question

calcule as raizes das funções :
m) y=2/3x-4/7
n) y=-5/8x+9/4
0) y=8/7x-5

Answer 1

calcule as raizes das funções :
m)
y=2/3x-4/7

2/3x-4/7=0
2/3x=4/7
x=4/7•3/2
x=12/14
x=6/7

n)
y=-5/8x+9/4

-5/8+9/4=0
-5/8x= -9/4
x=-9/4•(-8/5)
x=72/20
x=18/5

0)
y=8/7x-5

8/7x-5= 0
8/7x=5
8x=5•7/8
x=35/8



bons estudos!
