X-y=7
so you have to rewrite the equation in the form of mx+b=y
so ... x-y=7
-x -x
-y=7-x then simplify
-y(-y)=-(7-x) multiply both sides by -1
y=-7+x
which is the same y= x-7
y=x+-7
Answer:
(0,-4) (1,-2) (2,0)
Step-by-step explanation:
2x-y = 4
solve for y
subtract 2x from each side
-y = -2x+4
multiply by -1
y =2x-4
three points
let x= 0
y = -4
(0,-4)
let x = 1
y = 2(1) -4
y = -2
(1,-2)
let x =2
y = 2(2) -4
y =4-4
(2,0)
G(x) = (1/4)^x
Find g(-3) this means to replace x with -3
G(-3) = (1/4)^-3
Apply the negative exponent rule :
A^-b = 1/a^b
G(-3) = 1/(1/4)^3
G(-3) = 1/ (1/64)
G(-3) = 64
Answer: 64
