y=1-7x
Step-by-step explanation:
7x+y=1
The first thing to do is get the y by its self. So u cancel the 7x out by-7x and bring it to the other side.
7x-7x = 0
Now all we have left is: y=1-7x

Answer:
1) 5
2) (3 , 24)
Step-by-step explanation:
Question 1
f(x) x= 1 2 * 5¹ = 10
f(x) x= 2 2 * 5² = 50
f(x) x= 3 2 * 5³ = 250
multiplicative rate of change = 50/10 = 5
check: 250/50 = 5
Question 2
f(x) = 2 * 4ˣ
(3 , 24) f(3) = 2 * 4³ = 2 * 64 = 128 ≠ 24
