We are given the points
<span>(0,-4),(1,0),(2,2)
The standard form a quadratic function (in terms of x) is
y = Ax2 + Bx + C
Subsitute the points
-4 = 0 + 0 + C
C = -4
0 = A + B - 4
2 = 4A + 2B - 4
Solve for A and B
A = -1
B = 5
The function is
y = -x2 + 5x - 4</span>
300 is the original amount and 0.5 is the rate (a percent) which is deacying because it is less than 1
Answer:
the area = 25
Step-by-step explanation:
a= side length x side length
a = 5 x 5
a = 25
Answer:
i guess this question miss the options to follow.
In any case the answer
You can see that 6 washes is 30 dollars so that would make each wash $5 and all other answers can be proven wrong or not proven to be true.
