Answer:
Y=168
Step-by-step explanation:
Y varies directly as X
Y=kx
K is a constant
28=k2
K=28/2 =14
Y=14x
Y=14×12
Y=168
Answer:
y+9=3/4(x-8)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=3/4(x-8)
y+9=3/4(x-8)
is strictly increasing on [0, 5], so

and

so the integral is bounded between

A day
= £9.20x7
= £64.40
6 days
£64.40x6= £386.40
The wages he has after he shared it with his mom
£386.40/7x5
= 55.20x5
= £276
£1932/£276= 7
It will take him 7 weeks to afford a car worth £1932.
