HOW WOULD I DO THIS??????????????
1 answer:
Answer:
i)
ii) (f-g)(x)=2x-5
iii) (f+g)(-1)=3
Step-by-step explanation:
f(x)=3x+1
g(x)=x+6
we are asked to determine
i) (f.g)(x) = f(x).g(x)
ii) (f-g)(x)=f(x)-g(x)
=(3x+1)-(x+6)
=3x+1-x-6
(f-g)(x)=2x-5
iii) (f+g)(x) = f(x) + g(x)
= (3x+1)+(x+6)
= 3x+x+1+6
(f+g)(x)=4x+7
(f+g)(-1)=4(-1)+7
=-4+7
(f+g)(-1)=3

Answer:
you can put the number on one side of the equation then the "x" part on the other side.
with c) 4x = 6-10
4x = -4
x = -4/4
x = -1
with d) 7x - 1 = 4x + 8
7x - 4x = 8 + 1
3x = 9
x = 9/3
x = 3

1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
x+11+3x+19=90
4x+30=90
4x=60
x=15
15+11 = 26
15x3+19 = 64
Ans: B
Hope this helps
