Hi there!

To derive an equation given the points, we can use the slope formula:

Plug in the corresponding coordinates:

Simplify:

Therefore, we have:
y = -4x + b
Plug in the x and y values for a coordinate to solve for b:
2 = -4(1) + b
2 = -4 + b
b = 6
The equation is:
y = -4x + 6. The correct answer is D.
Answer:
A
Step-by-step explanation:
Answer:
D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
The formula for the cost of the total sales is: 8a+5c where a is the number of adult tickets and c is the number of child tickers.
If he keeps 15% the formula is: 0.15(<span>8a+5c) </span>
Plus or minus 3. (The 1st answer)
x^2 means (-3*-3) which equals 9
x^2 means (3838) which also equals 9
6*9=54
