x=1 answer =1
Given:
(x₁,y₁) = (-2,4)
(x₂,y₂) = (0,2)
Determine the slope of the function
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 4) / (0 + 2)
m = -2/2
m = -1
Determine the equation
y - y₁ = m(x - x₁)
y - 4 = -1(x - (-2))
y - 4 = -1 (x + 2)
y - 4 = -x - 2
y = -x - 2 + 4
y = -x + 2
f(x) = -x + 2
The correct answer is first option
Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.
So it would be y=3+5 so you really just add 3+5 and that’s 8 so it would be y=8
