Answer:
x=4
y=1
Step-by-step explanation:
4x=7y+9
4x+y=17
7y+9+y=17
8y=17-9
8y=8
y=1
so
4x=7*1+9
4x=16
x=16/4
x=4
Answer:
below
Step-by-step explanation:
f(3)=2
f(20)=0
f(8)=4
f(0)=-1
if f(x)=9 then x=4
if f(x)=4 then x=8
f(x)=0 then x=20
Answer:
Option D is correct.
Step-by-step explanation:
Given that
A ray is a defined term we have to give the reason of the above statement.
A ray is a line or a part of a line that has one endpoint which we defined and other goes on infinitely in only one direction.
One of the example is a sun's ray of light in space. Light from the sun originates and travels from the sun, and its path extends infinitely.\
Hence, we say that "A ray is a defined term because it travels forever in one direction"
Option D is correct.
