Answer:
yes to both
Step-by-step explanation:
For a relationship to be a function then each value of x must relate to exactly one unique value of y.
This is the case in this table as
2 → 76
4 → 152
6 → 228
All unique values thus a function
To determine if it is linear then the rate of change is constant for each set of ordered pairs. This is measured using the slope formula.
m = 
with (x₁, y₁ ) = (2, 76) and (x₂, y₂ ) = (4, 152 ) ← ordered pair from table
m = 
= 
= 38
Repeat with (x₁, y₁ ) = (4, 152) and (x₂, y₂ ) = (6, 228)
m = 
= = 38
Since rate of change is constant then function is linear
Answer:
Step-by-step explanation:
D
The correct answer is a. 47.10 - 25 + d = 97.43.
This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.
Also, Tina made a deposit of an amount that she can't remember. A deposit is adding a certain amount of money, so you have to +d.
This rules out option B.
The only option left is option A, which makes complete sense.
Answer:
0.02
Step-by-step explanation:
5/69.12=0.0723
3/69.12=0.0434
0.0723-0.0434=0.0289
=0.02
The answer is A. Because you can’t lose the amount of steps you took.
