Answer:
x = number of bicycles = 35
y = number of cars = 55
Step-by-step explanation:
Let
x = number of bicycles
y = number of cars
x + y = 80 (1)
2x + 4y = 270 (2)
From (1)
x = 80 - y
Substitute x = 80 - y into (2)
2x + 4y = 270 (2)
2(80 - y) + 4y = 270
160 - 2y + 4y = 270
- 2y + 4y = 270 - 160
2y = 110
y = 110/2
y = 55
Substitute y = 55 into (1)
x + y = 80 (1)
x + 55 = 80
x = 80 - 55
x = 35
x = number of bicycles = 35
y = number of cars = 55
Answer: h(3)= -4 h(-3)=-16
Step-by-step explanation:
Plug in 3 and -3 for x and solve
h(3)= 2(3)-10
h(-3)= 2(-3)-10
25-5x=5(-x+5)
25-5x=-5x+25
-5x+5x= 25-25
0=0
So the answer will be A: there is no solution
