Answer:
The point on the line is not filled in (so just a white circle) because the sign is an "equal to" sign. The line always faces the opposite side of the jaws, so in the case of x > 4, the line goes right starting from the hollow point above 4.
120
Step-by-step explanation:
Answer:False
first number= 19/5
second number= 2/5
first number= a
second number= b
a+3b=5 equation 1
b+2a=8 equation 2
using equation 2 we have
b=8-2a
using equation 1 we have
a+3(8-2a)=5
a+24-6a=5
24-5=6a-a
19=5a
a=19/5 = first number
so using b=8-2a
we have
b=8-2(19/5)
b=8-(38/5)
b=2/5 = second number
(-6,5)
