X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer: He added 4 to a negative 42 and said it was 46 but its supposed to simplify to -38. X=3/5
Answer:
(1,4),(2,12)
----------
The form is y = ab^x
12 = ab^2
4 = ab^1
------------
Divide the 1st by the 2nd to get:
3 = b
--------
Substitute that into the 2nd equation to solve for "a":
4 = a*3^1
a=(4/3)
-------------
EQUATION:
y = (4/3)*2^x
==================
Step-by-step explanation:
Answer: 16 different ways
Step-by-step explanation:
Add 1/3 on both sides
a= 1
