Answer:
Step-by-step explanation:
To create a system of equations, write an equation to model each condition that must be satisfied in the given situation.
It is given that x represents the width of the flower bed and that y represents the area of the base of the birdbath.
Write an equation to represent the condition regarding the planting area in the flower bed. It is given that there is 35 square feet of planting area. The flower bed is 3 feet longer than the width.
x(x+3) - y = 35
Write an equation to represent the condition regarding the cost of the soil and the birdbath. The question gives that the soil will cost $5 per square foot and the birdbath will cost $18 per square foot of the base.
5x(x+3)+18y=150
Combining both of the equations gives the following system of equations.
x(x+3)-y=35
5x(x+3)+18y=150
Answer:
42=2×15+12
Step-by-step explanation:
2×15=30
therefore 30+12=42
20. Let me know if you want a step by step.
The steepest line possible is a vertical line. Its slope is bigger than any
possible number you can think of, because it can change its height by
any amount in zero time. Its slope is 'undefined', meaning that there's
no number that can describe it. Some people would say it's 'infinity',
but that's not a number.
