Answer:
The equation would be y = x + 5, in which x is the number of weeks and y is the number of books he has.
Step-by-step explanation:
We know this because even at 0 weeks, he still has 5 books. Therefore we put this as the constant at the end. Then we can add the number of weeks since the rate is one book per week.
Answer:
We know that the multiplicative rate of change of a function is the number by which each next term of an exponential function is increasing or decreasing. We can find multiplicative rate of change by dividing any term of the function by its previous term.
The area of the model is 80 square foot
Step-by-step explanation:
Let the area of the house model be 'a'
The scale = 1:50
The area of the house= 4000 square foot
Area of the model =4000/50
a = 80 square foot
The area of the model is 80 square foot
-4x < 20
Divide -4 on both sides and the x would be by itself and 20/4 = 5. Since it is a negative, the sign would switch to >
This would be the inequality : x > 5
Numbers in the solution set would be any number greater than 5
ex: 6, 10, 15
Answer:
{-8,28}
Step-by-step explanation:
|10-x|=18
The absolute value has two solutions, one positive and one negative.
10-x = 18 and 10-x = -18
Subtract 10 from each side
10-10-x = 18-10 10-10-x=-18-10
-x = 8 -x = -28
Multiply each side by -1
x = -8 x = 28
