Answer:
d) 4(s + 4.5) and (s + 4.5) + (s + 4.5) + (s + 4.5) + (s + 4.5)
Step-by-step explanation:
since you know that one side is (s+4.5) and a square has 4 congruent sides the answer would be 4(s + 4.5) and (s + 4.5) + (s + 4.5) + (s + 4.5) + (s + 4.5)
Answer:
The change in the total cost for each book printed is $10
The cost to get started is $1250
Step-by-step explanation:
In the linear equation y = m x + b, where
- m is the rate of change per unit
- b is the initial amount (value y at x = 0)
∵ y represents the total cost of publishing a book in dollars
∵ x represents the number of copies of the book printed
∵ y = 1250 + 10 x
- Compare it with the linear equation y = m x + b
∴ m = 10
∴ b = 1250
∵ m = Δy/Δx
- That means m is the change in the total cost per book
∴ The change in the total cost for each book printed is $10
∵ b is value y at x = 0
- That means b is the cost to get started before print any book)
∴ The cost to get started is $1250
1/6 x = 2/3 |multiply both sides by 6
x = 12/3
x = 4
To find the coordinates of points A and B, go to Desmos and graph the given equation.
The word gradient means slope.
The slope is the coefficient of x in the equation. See it?
The gradient is 2.
Answer:
x > 5
Step-by-step explanation:
isolate x by subtracting 7 from both sides
x > 12 - 7
x > 5
