Answer:
1. [tex]4x + 5y \leq 60[/tex]
2. 15
3. 12
4. No, because if you put those values into the inequality you get
4 * 9 + 5 * 5 [tex]\leq[/tex] 60 --> [tex]36 + 25 \leq 60[/tex] --> [tex]61 \leq 60[/tex] which is not true.
Step-by-step explanation:
1. if a car costs $4, the total cost of cars is 4x
if a doll costs $5, the total cost of dolls is 5y
you have at most $60 to spend, so the amount you spend has to be less than or equal to 60.
The inequality would be [tex]4x + 5y \leq 60[/tex].
2. At the x-intercept y would be 0, so
4x + 5(0) = 60
4x = 60
x = 15
3. At the y-intercept, x would be 0, so
4(0) + 5y = 60
5y = 60
y = 12
4. Already explained in the answer
