25q + 10d = 33
B) q + d = 6
0.25q + 0.1d = 33
C) q + d = 33
25q + 10d = 6
D) q + d = 33
0.25q + 0.1d = 6

Answer: D) .
Step-by-step explanation:
We know that $1 = 4 quarters
⇒ 1 quarter =
$1 = 10 dimes
1 dime =
Let 'q' be the number of quarters and 'd' be the number of dimes.
Since, Martin has a combination of 33 quarters and dimes worth a total of $6.
Answer:
q + d = 33 0.25q + 0.1d = 6

f(x)=-2x^2+420x-4000
in form
f(x)=ax^2+bx+c
vertex (highest or lowest point, depending on graph)
vertex is -b/2a that is the x value
to find the profit, plug that x value back in
f(x)=-2x^2+420x-4000
-b/2a=-420/(2)(-2)=-420/-4=105
x min valu is 105
input to find profit
f(105)=-2(105-10)(105-200)
f(105)=-2(95)(-95)
f(105)=18050
max profit is $18050
Answer:
$18050 Is your answer

The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation thus option (B) is correct.
What is a linear function?
A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given points,
Let's take two-point (1,1) and (2,1.5)
The slope associated with the above points will be as,
(1.5 - 1)/(2 - 1) = 0.5
Thus, the line will be y = 0.5x + 0.3
Hence "The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation".
