Answer:
f(x) = x + 4
Step-by-step explanation:
Given
y - x - 4 = 0 ( add x to both sides )
y - 4 = x ( add 4 to both sides )
y = x + 4 ( let y = f(x) )
f(x) = x + 4
Answer:
I do but i need to remember my user give me a sec
The food service gave out 80 samples, which is 4 fewer than 70% of the total number of samples they prepared. Lets make x the total number of samples they prepared.
So lets write it as an equation
80 = (70% of x) -4
70% converts to a decimal by moving the decimal point 2 spaces up, so it is 0.7
80 = 0.7x-4
Add 4 to both sides of the equation
84 = 0.7x
Divide both sides by 0.7 to isolate the x
x = 120
The food service prepared 120 samples.

A. None of the answers are correct
Step-by-step explanation:
∠3 is a verticle angle to ∠1
linear pair means they add up to 180
complementary mean they add up to 90
