Answer:
Total cost = f + ad
Step-by-step explanation:
Given:
Number of days = d
Fixed charges = f
Cost per day = a
Find:
Equation
Computation:
Total cost = fixed cost + (Number of days)(Cost per day)
Total cost = f + ad
X is the amount of distilled water that must be added (in milliliters)
2/(100+x)=9/(1000)
2000=900+9x
1100=9x
122.22=x
x= 122
The answer is 122 milliliters of distilled water must be added
Answer:

Answer:
(-2, 4)
Step-by-step explanation:
~When reflecting a point of the x-axis, the x value (or first number inside the parenthesis) does not change.
The reason the x-value does not change is because you are reflecting over the x-axis, making the point go up or down. That will change the y-value but the x-value only changes if you move to the left or the right. In this case, you can see that the point's x-value is -2, so that will not change. It's current y-value however is -4. When reflecting over an axis, the number that is changing (in this case the y-value) will just be flipped from positive to negative, or vise versa. In this case, -4 will be reflected to be 4, making point C reflected over the x-axis (-2, 4).
Which of the following sequences are not geometric? (check all that apply) a. 2,10,50,250,1250 b. 1,4,9,16,25,36 c. -4,-2,-1,-0.
Romashka [77]
A is geometric because each number is multiplied by 5.
B is not geometric because it is an arithmetic sequence.
C is a geometric sequence because each number is divided by 2.
D is neither geometric not arithmetic because there is no common ratio and there is not a pattern being added or subtracted to each number.
So, your answer should be B and D.
