Easy, if he has $90 in ALL
and he spends $5 and $15
$20 in total
take, 90-20=70
So now he only has $70 left.
If each ride costs $1.50, then he's losing money.
So, y=-1.50x+70
So around the 47th ride he will have no more money.
Answer:
0
Step-by-step explanation:
product is another word for +
decreased is another word for -
____________________________
(7 + 8) - x
so
(7+8) - 15
15 - 15
= 0
Step-by-step explanation:
since it is perpendicular the eqxn be
3×-2y=c
it passes through (-4,-3) so
-12+6=c
c=-6
so eqxn becomes 3x-2y+6=0
Answer:
4w+56
Step-by-step explanation:
4(w) = 4w
4(14)= 56
4w+56
Answer:
15/56x^(-4/7) + 32x^3 + 6.
Step-by-step explanation:
Using the rule for algebraic differentiation:
If y = ax^n, dy/dx = anx^(n-1).
So :
If y = 5/8x^3/7 + 8x^4 + 6x - 9
dy/dx = 5/8* 3/7 x^(3/7-1) + 8*4 x^(4-1) + 6x(1-1)
= 15/56x^(-4/7) + 32x^3 + 6.
