Answer:
(5,1)
Step-by-step explanation:
Given :
Solution :
Equation 1 : y=x-4
Equation 2 : y = -x+6
We will use substitution method
Putting the value of y from equation 1 in equation 2
⇒
⇒
⇒
⇒
⇒
Now substituting value of x in equation 1 to get value of y
⇒
⇒
⇒
Thus the solution of given system of equations is (5,1)
We have also solved it by graphing the equations
You can refer the attached figure.
Answer:
The number is log 47base9
Answer:
a.No
b.-7/2, it is at (4,-7/2)
c.-5?4, it is at (2,-5/4)
d.All real numbers except 6
e.3
f.-1/2
Step-by-step explanation:
a. Plug it in! f(5)=((5)+3)/((5)-6)=-8, so no!
b. Plug it in! f(4)=((4)+3)/((4)-6)=-7/2
c. Plug it in! f(2)=((2)+3)/((2)-6)=-5/4
d. If it were to be 6, then it would be 3/0 which would be undefined.
d.f(-3)=((-3)+3)/((-3)-6))=0/8
f.f(0)=((0)+3)/((0)-6)=-1/2
Answer:
0
Step-by-step explanation:
There is no 7
