Step-by-step explanation:
14 1/8 - 12 5/9
1/8x4/4=4/36
1/8= 4/36
5/9x4/4= 20/36
14-12= 2
2-20/36= 1 20/36
Answer:
x=6
Step-by-step explanation:
since y=5x/2-7, and y=4x/3
so 5x/2-7=4x/3
5x/2-4x/3= 7
15x-8x/6=7
7x/6=7
x= 7*6/7= 6
F(x)=3x^2 - 2x +1
f(-1)=3(-1)^2-2(-1)+1
f(-1)=3( 1 ) +2+1
f(-1)=3+3
f(-1)=6
