The rate of change is constant in the graph. Find the rate of change. Explain what the rate of change means for the situation.
A. -(100)/(3); value drops $100 every 3 years.
B. –1; value drops $1 every year.
C. –100; value drops $100 every year.
D. –3; value drops $3 every year.
Answers
Answer:
A. -(100)/(3); value drops $100 every 3 years.
Step-by-step explanation:
The rate of change here, is the how much the value of the refrigerator increases per unit of time, in years. Since, the value of the fridge decreases, the rate of change is negative.
It is a linear graph i.e. the instantaneous rate of change and average rate of change are the same. Now, all you have to do is pick any two arbitrary points, preferably the x-intercept and y-intercept for simplicity and find the change in y and the change in x. The change in y and x will be the difference of the x and y coordinate of the points you chose. It does not matter which order you subtract in. Just remain consistent between your 2 points. The change in y is your rise, the change in x is your run. Slope is rise over run. So then divide.
Δy=400-0= $400
Δx = 0-12 = -12 yrs
Rate of change = rise/run = 400/(-12)=100/-3= -33.333 $/yrs
Answer:
The rate of of change is -100/3, or -33.33. This means that every year, the resale value of a refridgerator goes down by about $33.33
Step-by-step explanation:
rate of change formula : f(b)-f(a)/b-a
200-300/6-3
= -100/3
=-33.33

Answers
Answer:
7 grams of protein
Step-by-step explanation:
C = 9f + 4p + 4c
Plug the given information into the given formula
179 = 9(3) + 4p + 4(31)
Use PEMDAS
179 = 27 + 4p + 124
Combine like terms
179 = 151 + 4p
Subtract both sides by 151 to isolate variable p
179 - 151 = 4p
28 = 4p
Divide both sides by 4 to isolate variable p
28 ÷ 4 = p
7 = p

Which number line shows the solution to inequality 3x – 3 < 12?
Answers
Answer:
A
Step-by-step explanation:
The Graph "A" show the value of x in inequality 3x – 3 < 12
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
What does open circle and close circle shows in graph?A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".
According to the question
Given inequality 3x – 3 < 12
Solving for x
3x – 3 < 12
3x < 12 + 3
3x < 15
x < 5
Open circle will be used to show the greater than sign
Therefore,
Graph A shows the inequality .
Hence, the Graph "A" show the value of x in inequality 3x – 3 < 12

A shop contained some refrigerator and televisions. The total number is 800, and 45% of them were refrigerator, and 65[infinity] of the televisions, were sold last week , how many fewer refrigerators were sold than televisions
Answers
Answer:
The answer is below
Step-by-step explanation:
A shop contained some refrigerators and televisions. The total number is 800, and 45% of them were refrigerators. If 60% of refrigerators were sold and 65% of televisions were sold last week. How many fewer refrigerators were sold than televisions?
Solution:
The number of refrigerators = 45% of 800 = 0.45 * 800 = 360 refrigerators.
The number of televisions = 800 - 360 = 440 televisions.
number of refrigerators sold = 60% of 360 = 0.6 * 360 = 216 refrigerators
number of televisions sold = 65% of 440 = 0.65 * 440 = 286 televisions
The number of fewer refrigerators that were sold than televisions = 286 - 216 = 70
